Enhanced SRST

This chapter describes the Unified Enhanced Survivable Remote Site Telephony (Unified E-SRST) feature which is an enhancement of the SRST feature that provides advanced services compared to the classic Unified SRST.

Migration from Cisco Unified SRST Manager to Unified E-SRST

Cisco Unified Survivable Remote Site Telephony Manager is End-of-Life (EOL). Hence, provisioning for Unified E-SRST through Cisco Unified SRST Manager is not supported for Unified E-SRST Release 12.2 and later releases. Unified E-SRST is provisioned only using CLI commands (manual provisioning) to support fall back of phones registered to Cisco Unified Communications Manager. For more information on configuring Unified E-SRST see SIP: Configure Unified E-SRST and SCCP: Configure Unified E-SRST.

For information on Cisco Unified Survivable Remote Site Telephony Manager End-of-Life announcement, see Cisco Unified Survivable Remote Site Telephony Manager Product Bulletin.

Cisco Unified SRST Manager is a GUI-based tool that helps to monitor, report, and troubleshoot remote sites. It performs automatic sync up between the Cisco Unified Communications Manager and the Unified E-SRST gateway that helps in adding, deleting, and modifying the users and phones including dial-plan mapping. It also provides centralized management and control of all remote sites. For more information on the Cisco Unified SRST Manager that is End-of-Life, see Administration Guide for Cisco Unified SRST Manager.

Benefits

When you configure Unified E-SRST, it provides the following feature benefits in comparison to the classic Cisco Unified SRST:

  • Voice Hunt Group

    • Shared Lines

    • Mixed Shared Lines (SIP and SCCP Phones)

    • Hunt Statistics Collection

    • Mixed Deployment (SIP and SCCP Phones)

  • Unified E-SRST is supported on Cisco Catalyst 8200L Series Edge Platforms with Cisco IOS XE Bengaluru 17.5.1a and later releases.

Licensing

This section provides information on licensing of Cisco Unified Enhanced Survivable Remote Site Telephony (Unified E-SRST).

Cisco Smart Licensing for Unified E-SRST

Cisco Smart Licensing is a software licensing model that provides visibility of ownership and usage through the Cisco Smart Software Manager (CSSM) portal. CSSM is a central license repository that manages licenses across all Cisco products that you own, including Unified E-SRST. Devices send license usage to CSSM either directly or use an on-premises satellite. Your Smart Account Administrator controls your access to CSSM. Use your Cisco credentials to access the CSSM portal using http://software.cisco.com.

Smart Licensing applies to all platform technology (DNA subscription) and Unified E-SRST feature licenses that the router uses. Unified E-SRST requires one license entitlement (SRST_E_EP) for each configured SIP or SCCP phone.

Starting from Cisco IOS XE 17.18.1a release, the Cisco Smart Licensing is updated to report with flex subscription entitlement tag (SRST_EP_SUB) across all the supported platforms. To maintain the continued support and entitlements to the future application versions, purchase a collaboration flex subscription.

CSSM shows license usage across all registered devices to a virtual account. A Virtual Account License Inventory displays the quantity of licenses that are purchased, those licenses in use, and a balance. An Insufficient Licenses alert is displayed if the license balance is below 0.

For example, consider a smart account in CSSM with 50 SRST_E_EP licenses. If you have a single registered Unified E-SRST router with 20 configured phones, the CSSM licenses page shows Purchased as 50, In Use as 20 and Balance as 30.

For more information on Smart Software Manager, see the Cisco Smart Software Manager User Guide.


Note

The SRST_E_EP license count reflects the total phone count for both the ephones and voice register Pools that are configured in the Unified E-SRST irrespective of registered or nonregistered phones. Reports license usage three minutes after the last configuration change, to avoid unnecessary reporting while configuring Unified E-SRST.


Note

Unified E-SRST Smart Licenses also provide RTU entitlement for routers that are not configured for Smart Licensing.

Smart License Operation

Cisco IOS XE 17.18.1a Release Onwards

Starting from Cisco IOS XE 17.18.1a release, the Cisco Smart Licensing is updated to report with flex subscription entitlement tag (SRST_EP_SUB ) across all the supported platforms.

To maintain the continued support and entitlements to the future application versions, purchase a collaboration flex subscription.

Cisco IOS XE Everest 16.5.1 Release to Cisco IOS XE Fuji 16.9.1 Release

Cisco 4000 Series Integrated Services Routers support Smart Licensing as an alternative to Cisco Software RTU Licensing. Use the license smart enable command to enable Smart Licensing. To disable Smart Licensing, use the no form of the command and re-accept the EULA using the license accept end user agreement command.

Cisco IOS XE Gibraltar 16.10.1 Release Onwards

The Cisco RTU Licensing and the CLI license smart enable command are deprecated. Smart Licensing is mandatory from this release.

Cisco IOS XE Everest 16.5.1 Release to Cisco IOS XE Amsterdam 17.3.1a Release

Routers configured to use Smart Licensing offer a 90-day evaluation period, during which you can use all the features without registering to CSSM. A Unified E-SRST device is associated with CSSM using a registration token. You can obtain the registration token from the virtual CSSM account or from an on-premises satellite. Once registered, the evaluation period pauses and you can use the balance later. You cannot renew the evaluation period on its expiry.


Warning

Unified E-SRST shuts down when the router is unregistered and allowed to pass into the Evaluation Expired state.

To register the Unified E-SRST router with CSSM, use license smart register idtoken command. For information on registering the device with CSSM, see Software Activation Configuration Guide.

Upon successful registration, the device sends an authorization request to CSSM for the licenses in use. For each license type requested, if the Smart Account has sufficient licenses, CSSM responds with Authorized . If the Smart Account does not have sufficient licenses, CSSM responds with Out of Compliance .

Post successful authorization of the request, licenses are bound to the requesting device until the next authorization request submission. An authorization request is sent every 30 days or when there is any change in license consumption, to maintain the registration with CSSM. The authorization expires if you do not update the license request for the router within 90 days. The certificate issued to identify the router at the time of registration is valid for one year and renewed every six months.

Cisco IOS XE Gibraltar 16.12.1 Release to Cisco IOS XE Amsterdam 17.3.1a Release

Cisco 4000 Series Integrated Services Routers supports Specific License Reservation (SLR). SLR allows reservation and utilization of Cisco Smart Licenses without communicating the license information to CSSM. To reserve specific licenses for a device, generate the request code from the device. Enter the request code in CSSM along with the required licenses and their quantity, and generate authorization code. Enter the authorization code on the device to map the license to the Unique Device identifier (UDI).

Cisco IOS XE Amsterdam 17.3.2 and Cisco IOS XE Bengaluru 17.4.1a Release Onwards

This release introduces a new paradigm for tracking license usage across your business. In earlier releases, license authorization was forward looking, binding licenses to a device until the next authorization request. Actual license usage during the proceeding reporting period is sent to CSSM, allowing you to plan ongoing license requirements based on historical usage data. Initial device registration is no longer required to use most platform functionality and deprecates the evaluation period.

Submits the license usage reports periodically according to a minimum reporting policy set for your account. Typically, this period could be once per year. However, you can generate reports more frequently if the use of licensed features varies over time. CSSM acknowledges each Resource Utilization Monitoring (RUM) report to ensure reliable recording of the usage. If the router does not receive an acknowledgment within the minimum reporting period, disables the call processing. Resumes the call processing on receiving a valid acknowledgment.

Submit the reports directly to the CSSM or through a satellite. Cisco Smart Licensing Utility (CSLU) applications can also receive usage reports, providing you with more flexibility in managing your license usage. Also, when a device is not able to communicate directly with a licensing server, a signed usage report can be generated and manually uploaded to CSSM. The acknowledgment generated by CSSM must be uploaded to the device within the license reporting policy period to ensure continued use.

As license reporting is now based on historical usage, the registration process used previously has been replaced with a trust association that also defines the reporting policy set in your account. Establishing trust with CSSM or Cisco Smart Software Manager Satellite uses an identity token similar to earlier registrations. Use the license smart trust idtoken token command to establish the trust relationship within the initial reporting period set for the device. The CLI license smart register command is deprecated from this release.

Current license usage for Unified E-SRST is displayed using the show license summary command: 

Router# sh license summary

Toll Fraud Prevention for SIP Line Side on Unified E-SRST

Unified E-SRST Release 12.6 enhances the existing Toll Fraud Prevention feature by enforcing security on the SIP line side of Unified E-SRST. The feature enhancement secures the Unified E-SRST system against potential toll fraud exploitation by unauthorized users from the SIP line side.

The configuration and characteristics of toll fraud prevention offered on the SIP line side of Unified E-SRST is same as the support available on Cisco Unified SRST. For more information on the feature, see Toll Fraud Prevention for SIP Line Side on Cisco Unified SRST.

Unified E-SRST with Support for Voice Hunt Group

The Unified E-SRST Release 12.2 supports the Voice Hunt Group with Cisco Unified Enhanced Survivable Remote Site Telephony (Unified E-SRST). The deployment supports the SIP and SCCP phones. The Cisco IP Phone 7800 and 8800 Series are the supported SIP phones for this deployment. The Unified E-SRST deployment introduces the voice hunt group enhancement on the Cisco 4000 Series Integrated Services Routers.

As part of the enhancement, supports the voice hunt group features in the E-SRST mode. The Unified E-SRST 12.2 and later releases supports the voice hunt group deployments with Sequential, Parallel, Longest idle, and Peer call blasting.

During a WAN outage, the SIP phones on the Cisco Unified Communications Manager (Cisco Unified Communications Manager) fallback to Unified E-SRST router in mode esrst . By default, logs the SIP phones in to the hunt group. However, if the CLI command members logout is configured under the voice hunt group configuration mode, the phones are in logged out state. In the Unified E-SRST mode, the phone that falls back on Unified E-SRST can toggle state. It can also log in (or log out) to the voice hunt group using HLog in Feature Access Code (FAC). Displays the DN status (logged in or logged out) on the registered phones with Unified E-SRST. The following FAC codes are available as part of the enhancement introduced on Unified E-SRST:

  • FAC Standard (Code: *5)

  • FAC Custom (Code: Customizable, with maximum character string length of 10. For example, *89, 8888888888)

When the user inputs FAC from a phone with multiple lines, the log out behavior is different across a deployment with the common voice register Pool configuration and the individual voice register Pool configuration.

  • Common Voice Register Pool Configuration: The DN's log out individually, and not at the phone level.

  • Individual Voice Register Pool Configuration: The DN's log out at the phone level, irrespective of the user providing the DN (primary, secondary, and so on) from which FAC input.

When the WAN is available, the phones register back with Cisco Unified Communications Manager. For a sample configuration of Unified E-SRST with voice hunt group enhancements, see Example for configuring Unified E- SRST with Voice Hunt Group Enhancements.

The Unified E-SRST 12.2 Release introduces support for the voice hunt group with shared lines and mixed shared lines (SCCP and SIP phones). For a mixed shared line supported with the voice hunt group, configure only individual voice register Pools. Does not support the common voice register Pools. For a sample configuration of mixed shared lines configured for a voice hunt group on Unified E-SRST, see Example for Configuring Shared Line with Voice Hunt Group on Unified E-SRST.

Also, supports hunt statistic collection for Unified E-SRST 12.2 and later releases.

A mixed deployment of SIP and SCCP phones supports the Unified E-SRST, Release 12.2. Supports Hunt Group Logout from a mixed deployment of SIP and SCCP phones using:

  • FAC

  • Feature Button, or DND

Supports Line level logout and phone level log out using FAC (*4).


Note

Does not support Hunt Group logout for shared lines. Shared lines retain their logged in status.

Support for B-ACD in Unified E-SRST

The Unified E-SRST Release 12.2 enhancement supports B-ACD. For SIP phones that fall back to Unified E-SRST router in mode esrst , you must ensure that the CLI command members logout is configured. The Members Logout functionality handles the login back from the phones using FAC. It also supports call Delivery to Voice Hunt Group from B-ACD.

For a sample configuration, see Example for Configuring B-ACD with Unified E-SRST.

Recommendations for Configuring Voice Hunt Group on Unified E-SRST

The Unified E-SRST Release with Support for voice hunt group has the following design characteristics:

  • For all the directory numbers falling back from Cisco Unified Communications Manager, a common voice register Pool configuration and an individual voice register Pool configuration is supported for this deployment. An individual voice register pool configured with the CLI command id device-id-name , along with voice register dn configuration, is recommended.

  • Ensure that the CLI command mode esrst is configured under voice register global configuration mode for phones to fall back to Unified E-SRST.

  • Ensure that the CLI command id ip or id device-id-name is configured under voice register pool configuration mode, along with voice register dn configuration, for a deployment with individual voice register Pool configuration. For a sample configuration, see Example for configuring Unified E- SRST with Voice Hunt Group Enhancements.

  • Ensure that the CLI command id device-id-name is preferred over id ip as the CLI command to configure under voice register pool configuration mode. This scenario occurs where the IP address of the phone changes due to the DHCP configured on the phone.

  • Ensure that the CLI command id network is configured under voice register pool configuration mode for a deployment with common voice register Pool configuration. The recommended configuration is id network 8.55.0.0 255.255.0.0 so as to facilitate registration of phones falling back on Unified E-SRST from Cisco Unified Communications Manager.

  • Ensure that the CLI command members logout is configured under voice hunt-group configuration mode. The CLI is applied by default when the SIP phones fall back to Unified E-SRST from Cisco Unified Communications Manager.

  • Ensure that the CLI command fac standard is configured under telephony-service configuration mode. If you want to configure a FAC code other than *5, you must configure the CLI command fac custom under telephony-service configuration mode.

  • Ensure that the CLI commands call-park system application andhunt-group logout hlog are configured under telephony-service configuration mode. The CLI commands are mandatory configuration for FAC functionality to work.

For steps on configuring voice hunt groups on Unified E-SRST, see Configure Voice Hunt Groups on Unified E-SRST.

For a sample configuration of voice hunt groups on Unified E-SRST, see Example for configuring Unified E- SRST with Voice Hunt Group Enhancements.

SIP: Configure Unified E-SRST

The Enhanced SRST for Cisco Unified SIP IP Phones feature supports version negotiation between the SIP phones and ESRST to enable more features in the Cisco Unified E-SRST mode. In the current scenario, when the SIP phones fall back to the SRST mode, disables features such as Shared-Line, Busy-Lamp-Field (BLF), and Video call on the phones. The SRST mode does not support these features. However, with the Enhanced Survivable Remote Site Telephony (E-SRST) deployment, you can enable the basic and supplementary call features. Also, you can enable the following features using version negotiation:

  • Shared-Line

  • Busy-Lamp-Field (BLF)

  • Video Calls

The following table contains a list of supported features and the expected behavior of the features in the E-SRST mode.

  • To enable version negotiation feature between ESRST & phone, you must configure "mode esrst" under the voice register global mode.

  • We recommended using the SRST manager to automate the CLI provisioning of ESRST branch routers.

For more information on SRST, see the Cisco Unified SRST Manager Administration Guide.

Restrictions

  • Supports the Version Negotiation feature only on the Cisco Unified 9951, 9971, 8961 SIP IP phones, Cisco IP Phone 7800, and 8800 Series.

  • The phone firmware version is version 9.4.1 or later versions.

  • This feature supports video calls only between the local Cisco Unified SIP IP phones and the No Time-Division Multiplexing (TDM) video calls during the SRST failovers.

  • To enable phone-specific features like shared-line & BLF work, configure the individual voice register Pools.
