Call-control and call-quality requirements are in addition to the guidelines above and should be calculated using the bandwidth recommendations in the applicable Cisco Unified Communications SRND at http://www.cisco.com/c/en/us/solutions/enterprise/unified-communication-system/index.html.
  • When both the subscriber and publisher are taking calls, the maximum round-trip latency must be no more than 100 ms. When only the publisher is taking calls, subscriber is idle but replicating with publisher, the maximum round-trip latency must be no more than 150 ms.
  • The network must use the following load-balancing techniques for connections to the Unity Connection servers:
    • The Unity Connection servers are assigned a common DNS name with the publisher server first.
    • All user clients like Jabber, WebInbox etc and administrator sessions connect to the publisher server. If the publisher server stops functioning, the user client and administrator sessions must connect to the subscriber server.


    • Caution

      If failover happens and publisher node of Unity Connection cluster is not completely down then subscriber node will become primary node and user clients (Jabber,Web Inbox etc..) will still connect to publisher node.However, users may experience delay in accessing the voicemail through clients. In this case administrator should configure the RTMT alerts "AutoFailbackInitiated and AutoFailbackSucceeded" to troubleshoot failover. For more information on configuration of these alarms refer Alarm Message Definitions for Cisco Unity Connection Release 11.x guide available at link https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/alarm_messages/11cucalrmmsgdef.html. In order to experience seamless voicemail access experience through user clients(Jabber, Web Inbox etc.. ) for Cisco Unity Connection failover scenario as mentioned above, it is recommended to either deploy the Unity Connection Cluster with maximum round-trip latency for not more than 5ms when both servers are in separate buildings or sites. Or customer should plan to install both servers in same building or sites. Refer section “Cluster Requirements When Both Servers are Installed in the Same Building or Site” of System Requirements for Cisco Unity Connection Release 11.x guide available at link https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/requirements/b_11xcucsysreqs.html
    • Phone systems must attempt to route incoming calls to the subscriber server. If no voice messaging ports are available to answer calls on the subscriber server, the phone systems must route calls to the publisher server.
  • The TCP and UDP ports of the firewall must be open as listed in the IP Communications Required by Cisco Unity connection chapter of the Security Guide for Cisco Unity Connection, Release 11.x, at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/security/b_11xcucsecx.html.
  • Both Unity Connection servers must have the same software and engineering-special versions installed.
  • Both Unity Connection servers must have the same enabled features and configurations.
  • Both Unity Connection servers must be configured to be in the same time zone.
  • Both Unity Connection servers must connect to the same phone system(s).
  • If the Unity Connection servers contain dual NICs, the two NICs on each Unity Connection server must be configured for fault tolerance using a single IP address, or one of the NICs must be disabled. Configuring the two NICs with distinct IP addresses for network load balancing is not supported.
  • For selected servers supported for earlier versions of Unity Connection, a memory upgrade or replacement of hard disks. To determine whether your server requires a memory upgrade or replacement of hard disks, see the applicable server-specific table in the Cisco Unity Connection 11.x Supported Platforms List.

Note

The Unity Connection cluster feature is not supported for use with the SAML SSO feature.

Requirements for Unity Connection Networking

Unity Connection servers can be joined through intrasite networking to form a single site (known as a Digital Network). you may add upto a maximum of ten Untiy Connection server or cluster per site. In addition, two Unity Connection sites can be linked together through intersite networking for a total of up to 20 Unity Connection servers sharing the same directory information

Alternatively, you can use intersite networking to link a single Unity Connection site of up to ten servers with a single Cisco Unity server or Digital Network. (In a Unity Connection cluster, only the publisher server is joined to the network, so a cluster counts as a single server toward the limit of ten in each site.)

HTTPS networking can be used to link up to 25 Unity Connection servers or clusters in a single site network, referred to as HTTPS Unity Connection network.

Requirements for Intrasite Networking

Intrasite networking uses SMTP to provide directory synchronization and message networking among Unity Connection servers.

Unity Connection version 8.x, version 9.x, version 10.x, version 11.x servers can coexist in the same site as long as each 7.x server meets all the applicable requirements in the System Requirements for Cisco Unity Connection Release 8.x at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/8x/requirements/8xcucsysreqs.html.

Intrasite networking has the following requirements:

  • Each version 11.x server in the site must meet all applicable requirements listed in this document.
  • Each server in the site must be able to access the other servers in the site directly through TCP/IP port 25 (SMTP), or SMTP messages must be routed among the servers through an SMTP smart host.
  • If your site includes one or more Unity Connection clusters, you must have a smart host available to resolve the SMTP domain of the cluster to both the publisher and subscriber servers in order for message traffic to reach the cluster subscriber server in the event that the publisher server is down.
  • The virtual directory created by the networked Unity Connection servers must not exceed the maximum total numbers of objects listed in Table 7 in “Directory Object Limits for Unity Connection”.

    Note

    SAML SSO feature is not supported to access all the nodes of Intrasite networking. Only a local administrator can configure the Intrasite networking in Unity Connection..

Requirements for Intersite Networking

You can use intersite networking to link one Unity Connection site to another Unity Connection site. You can also use it to link a Unity Connection site to a Cisco Unity server or Cisco Unity Digital Network. The linked sites are called a Cisco Voicemail Organization.

Intersite networking has the following requirements:

  • Each Unity Connection server or cluster in the Cisco Voicemail Organization must be at version 11.x and must meet all applicable requirements listed in this document.
  • Each Unity Connection site must meet the requirements listed in the Requirements for Intersite Networking.

For more information on virtual servers and the specifications on the memory that must be added, see the Cisco Unity Connection 11.x Supported Platforms List at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/supported_platforms/b_11xcucspl.html.

  • The virtual directory created by the networked sites must not exceed the maximum total numbers of objects listed in Table 7 in the “Directory Object Limits for Unity Connection” .
  • Intersite networking can be used to link a maximum of two sites. (Adding more than one intersite link per site is not supported.)

Note

SAML SSO feature is not supported to access all the nodes of Intersite networking. Only a local administrator can configure the Intersite networking in Unity Connection.

Requirements for HTTPS Networking

You can use HTTPS networking to link one or more Unity Connection servers or clusters to form a well-connected network based on hub-spoke topology. The servers that are joined together in the network are referred as locations (Unity Connection cluster counts as one location in the network). Within a network, each location uses HTTP or HTTPS to exchange directory information and SMTP to exchange voice messages with each other.

HTTPS networking has the following requirements:

  • Each Unity Connection server or cluster in the HTTPS network must be at version 10.x or later, and must meet all applicable requirements listed in this document.

  • Each server in the network must be IP addressable and able to exchange directory information using HTTP on port 8081 or HTTPS on port 8444.

  • The servers in the network must be able to route SMTP messages to the other servers in the network directly through TCP/IP port 25 or through an SMTP smart host.

  • If your network includes one or more Unity Connection clusters, you must have a smart host available to resolve the SMTP domain of the cluster to both the publisher and subscriber servers, which helps divert message traffic to the subscriber server when the publisher server is down.

  • The virtual directory created by the networked Unity Connection servers must not exceed the maximum numbers of objects listed in Table 8 and Table 9 in the “Directory Object Limits for Unity Connection” section.

  • HTTPS networking can be used to link a maximum of 25 Unity Connection locations.

  • HTTPS networking supports single site network only. (Connecting multiple Unity Connection sites in a network is not supported.)

  • HTTPS networking is not supported with intrasite or intersite networking.


    Note

    HTTPS networking is not supported for use with Cisco Business Edition version 3000. Before using HTTPS networking, ensure that directory replication takes place properly in Intrasite or Intersite Networking. Also, the Unity Connection servers should be using appropriate OVA as per topology and directory size.

    Note

    SAML SSO feature is not supported to access all the nodes of HTTPS networking. Only a local administrator can configure the HTTPS networking in Unity Connection.

Requirements for Using Security Assertion Markup Language Single Sign-On (SAML SSO)

SAML SSO allows a user to gain single sign-on access with Unity Connection subscriber web interfaces and across the administrative web applications on the following Unified Communication products:

  • Cisco Unity Connection

  • Cisco Unified Communications Manager

  • Cisco Unified IM/Presence

For more information on accessing web application pages through SAML SSO, see the Quick Start Guide for SAML SSO in Cisco Unity Connection , Release 11.x, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/quick_start/guide/b_11xcucqssamlsso.html.

The SAML SSO feature requires the following third party applications:

  • LDAP Directory.

  • The Identity Provider authenticates an end user and returns SAML assertions. SAML Assertion shows either Yes (authenticated) or No (authentication fails) response. When an end user enters the username and password, the user credentials authenticates on Identity Provider. This further gives access to web applications on the Unity Connection server. The supported Identity Providers are:

    • Microsoft Active Directory Federation Services (ADFS) version 3.0, 4.0 and 5.0

    • Ping Federate version 6.10.0.4

    • OpenAM version 10.0.1

    • Oracle Identity Manager version 11.0

    • F5 BIG-IP 11.6.0

    • Okta 2017.38

  • To enable the SAML SSO feature from Cisco Unity Connection Administration, make sure you have at least one LDAP user in Unity Connection with administrator rights.


    Note

    Unity Connection supports SAML 2.0 protocol for the SAML SSO feature.

The third party products mentioned above must meet the following configuration requirements:

  • Active directory domain controllers/global catalog servers and Active Directory Federated Services (ADFS) can be installed in any hardware virtualization environment supported by Microsoft. (Cisco does not provide technical support for DC/ GCs or ADFS that acts as an Identity Provider).

  • The Identity Provider that you are using must be accessible by its hostname on the network to all the client systems like Unity Connection.

  • The clocks of all entities participating in SAML SSO must be synchronized.

See the third-party product documentation for more information about the above products.


Note

Make sure that Domain Name Server (DNS) is configured on Unity Connection as SAML SSO is not supported with only IP address configuration of Unity Connection.

All web browsers that are currently supported with Unity Connection 11.x, allows SAML SSO access to web client applications.

Requirements for VPIM Networking

Unity Connection supports Voice Profile for Internet Mail (VPIM) version 2 that allows the exchange of voice and text messages with other messaging systems.

VPIM Networking can be used to provide message networking between Unity Connection and the following messaging systems:

  • Unity Connection 11.x and 10.x, 9.x, 8.x, and 7.x..

  • Third-party voice messaging systems that support the VPIM version 2 protocol, as defined in Internet RFC 3801.

For information on using VPIM in Unity Connection Unity Connection in Cisco Business Edition, see the “VPIM Networking” chapter of the Networking Guide for Cisco Unity Connection, Release 11.x, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/networking/guide/b_11xcucnetx.html .

Requirements for Using a Provisioning Application

A supported provisioning application:

  • Unimax Second Nature version 6.8 B0 and later.

Any technical support or troubleshooting required on the provisioning software must be obtained from the manufacturer. Cisco is responsible for providing technical support only on the Unity Connection application.

Requirements for Migrating from Unity Connection 7.x to Version 11.x

During the migration, only user data and, optionally, voice messages are preserved. System-level configuration data (for example, templates and classes of service) must be manually configured.


Caution

Requirements for Unity Connection 11.x are different from requirements for Unity Connection 7.x. The system must meet Unity Connection 11.x requirements to receive support from Cisco TAC.

A migration from Unity Connection version 7.x to 11.x has the following requirements:


Caution

If you try to install version 11.x on an unsupported platform, Unity Connection will not be displayed as an option in the Product Deployment Selection window of the installation program.

Requirements for Migrating from Cisco Unity to Unity Connection Version 11.x Using a Gradual Migration


Caution

Requirements for Unity Connection are different from requirements for Cisco Unity. The system must meet Unity Connection 11.x requirements to receive support from Cisco TAC.

A migration from Cisco Unity to Unity Connection 11.x by gradually moving data has the following requirements:

  • All applicable requirements listed in this document.
  • A Cisco Unity Digital Network in which at least one server is running version 8.0(3) to act as a gateway to Unity Connection. Other servers in the Cisco Unity Digital Network must be running version 8.0(3) or later, or version 7.0(2) with Engineering Special (ES) 36 or later.
  • A server that is supported for use with Unity Connection and that meets Unity Connection 11.x specifications, particularly regarding memory and processor speed. (Not all servers supported for use with Cisco Unity are supported for use with Unity Connection.) For information on supported Unity Connection servers, including specifications on individual servers, see the Cisco Unity Connection 11.x Supported Platforms List available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/supported_platforms/b_11xcucspl.html.

Caution

If you try to install version 11.x on an unsupported platform, Unity Connection will not be displayed as an option in the Product Deployment Selection window of the installation program.

Note that voice cards are not supported for integrations with circuit-switched phone systems.

Requirements for Installing Unity Connection on a Virtual Machine

For information on installing other Cisco Unified Communications applications on the same physical server on which Unity Connection is installed, see the Unified Communications Virtualization wiki at http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-cisco-unity-connection.html.

  • If you are running Unity Connection on a physical server and want to migrate over to Unity Connection 11.x, then it is required to migrate from a physical server to a virtual server since the physical Unity Connection server is not supported for use with Unity Connection 11.x.
  • A physical host that meets Unity Connection specifications and that is supported for use in a virtualized environment. See the Cisco Unity Connection 11.x Supported Platforms List available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/supported_platforms/b_11xcucspl.html.
  • The applicable edition of VMware vSphere ESXi Version 5.0 Update 1, 5.5, 6.0, 6.5, 6.5 Update 2 and 6.7 installed on the host server on which the Unity Connection virtual machine will run.


    Note

    • Updates to ESXi Version 5.0 Update 1, 5.5, 6.0, 6.5, 6.5 Update 2 and 6.7 are supported.


  • For VMware configurations supporting 300GB and 500GB vDisks: The datastore where the Unity Connection virtual machine will reside must be formatted with a VMware VMFS block size large enough to allow for the intended size of the virtual hard disk for the Unity Connection virtual machine. For example, a block size of 1MB limits the maximum virtual hard disk size to 256GB. A block size of 2MB allows 512GB virtual disks.
  • Unity Connection 8.0(2) and later can be run on specification based hardware from Cisco, HP and IBM. However, some restrictions are applied. See http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/collaboration-virtualization-hardware.html for more information.
  • The support for the Input/Output devices on the servers that are running Unity Connection as a virtual appliance has been enhanced to include FCoE and Cisco Converged Network adapters. See http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/collaboration-virtualization-hardware.html for more information.
  • Unity Connection 8.0(2) and later now support FC, FCOE, iSCSI, and NFS SAN environments with some restrictions. See http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-collaboration-storage-design-requirements.html for more information.
  • For list of VMware features that are supported for Unity Connection, see http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-collaboration-storage-design-requirements.html.
  • Accessing a USB key is not supported.
  • Oversubscribing processors and memory is not supported.
  • For VMware vSphere ESXi 5.1 and earlier, at least one processor core must be available for the VMware ESXi hypervisor / scheduler.
  • For VMware vSphere ESXi 5.5 and later, Latency Sensitivity function is included to reduce virtual machine latency. When the Latency Sensitivity value is set to high you do not need to leave any unused processor core for the ESXi hypervisor / scheduler.
  • All virtual disks assigned to the Unity Connection virtual machine must be configured in independent-persistent mode, which provides the best storage performance.
  • A network time protocol (NTP) server must be accessible to the Unity Connection server.
  • When configuring a Unity Connection cluster, you can install Unity Connection on one physical server and one virtual machine, or on two virtual machines, but the two virtual machines must be on separate physical hosts. When using blades as hosts, we recommend that the blades be on separate chassis.
  • If the hyper-threading feature is available on the CPU, you should enable the feature to create logical cores. However, the logical cores do not change the Unity Connection rule that is based on 1:1 mapping of physical cores to vcpu not the logical cores to vcpu.

Directory Object Limits for Unity Connection

This section contains two tables that list directory object limits.

Table 6lists the maximum numbers of certain objects that can be created on a Unity Connection server. For these objects, the limits apply regardless of the platform overlay in use by the server.

If you are using legacy (intrasite or intersite networking) or HTTPS networking to link Unity Connection servers, the limits in Table 6 apply to each Unity Connection server in the site or organization.

Table 7 applies to the virtual directory created by the networked Unity Connection servers. When Unity Connection servers are networked together using intrasite networking, replication between locations creates the virtual directory consisting of the users, administrator-defined contacts, system distribution lists, partitions, search spaces, and VPIM locations that are homed on each location, along with data about the locations themselves. When servers are networked together using intersite networking, the virtual directory for an individual server consists of all users from both sites plus the administrator-defined contacts local to the site to which the server belongs, along with the system distribution lists, partitions, and search spaces on both sites, plus the VPIM locations on the local site.

Table 8 and Table 9 apply to the virtual directory created by the Unity Connection servers connected in an HTTPS network. When Unity Connection servers are linked together using HTTPS networking, replication between locations creates the virtual directory consisting of the users, administrator-defined contacts, system distribution lists, partitions, search spaces, VPIM locations, and VPIM contacts homed on each location along with the data about the locations themselves. The directory object limits for other objects that depend on the platform overlay are listed in the Cisco Unity Connection 11.x Supported Platforms List at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/supported_platforms/b_11xcucspl.html.

The limits in Table 7 apply to the entire site or Cisco Voicemail Organization, regardless of whether the network comprises only two locations or the maximum number of supported locations. (For example, in Unity Connection version 12.x, if the individual server platforms support the limits, you can have 10 locations in one site with 10,000 Unity Connection users each, or 20 locations in two sites with 5,000 Unity Connection users each.)

The limits in Table 8 apply to the entire network assuming that the locations use virtual platform overlay supporting 20,000 users.

  • Searching for Search Spaces in the System Administration slows down
  • Modifying and saving search spaces can take over 6 minutes.
  • Changing/ Saving/ Reordering Search spaces can take upto 20 mins to replicate across the site.

Table 9 lists the maximum number of certain objects in HTTPS network supported with different platform overlays. The limits mentioned in the table apply to the network assuming that all the Unity Connection locations in the network are of same platform overlay.

Note

It is required to connect 1vCPU server as a spoke location in the network.
  • 1vCPU server cannot be connected as a hub in the network.

Maximum Unity Connection locations supported in HTTPS network are determined based on the following criteria:

  • Depth of HTTPS network can reach up to second level.

  • Servers used in the network are of same virtual platform overlay.

  • HTTPS links supported at each location are same as mentioned in Table 9.

  • Maximum of 25 locations can be connected in the network.


For example, if an HTTPS network is created with only 2vCPU servers and each location supports a maximum of 3 HTTPS links then up to 10 locations can be connected in the network. Similarly, the number of Unity Connection locations supported in an HTTPS network is calculated for other virtual platform overlays used by the servers.


Note

An HTTPS Network can be created with a combination of different platform overlays based on the following considerations:
  • The number of locations that can be connected in an HTTPS Network is governed by the highest platform overlay used in the network.

  • The directory size depends upon the lowest platform overlay used in the network.


Available Languages for Unity Connection Components


Note

Languages are not licensed, and Unity Connection does not enforce a limit on the number of languages you can install and use. However, the more languages you install, the less hard-disk space is available for storing voice messages. In the Cisco Unity Connection 11.x Supported Platforms List available at link https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/supported_platforms/b_11xcucspl.html, information on the number of minutes of storage available on each server assumes that you have installed no more than five languages.

This section lists the languages in which Unity Connection components are available.
