Requirements

Server Requirements

Cisco Product Requirements

Deploy Cisco Jabber Guest with an existing Cisco Unified Communications Manager installation.

To allow Cisco Jabber Guest to access devices located inside the enterprise firewall, deploy the following:

  • Cisco Unified Communications Manager 8.6.x or later

    Cisco Jabber Guest requires that your Cisco Unified Communications Manager be configured to work with Cisco Expressway.

  • Cisco Jabber Guest Server

  • Cisco Expressway-C X8.2 or later

  • Cisco Expressway-E X8.2 or later


    Important

    • Without Cisco Expressway-C and Cisco Expressway-E, you are limited to testing with clients that can directly access the network on which the Cisco Jabber Guest server is homed.

    • You cannot use the same Cisco Expressway-C and Cisco Expressway-E pair or cluster for both Cisco Jabber Guest and Expressway for Mobile and Remote Access.

For more information, download the Cisco Expressway Administrator Guide, deployment guides, and release notes or see the online help for complete information on configuring the options available on your Cisco Expressway.

Reverse Proxy Server Requirements

The Cisco Expressway-E and Cisco Expressway-C can be used to tunnel HTTP from the Cisco Jabber Guest client to the Cisco Jabber Guest server. If a third-party reverse proxy is used in front of the Cisco Expressway-E, configure it to proxy only the following URL types:

  • /call

  • /jabberc (used for HTTP/call control)

Configure the reverse proxy to redirect any HTTP requests to HTTPS.

Virtual Machine Requirements

Cisco Jabber Guest is deployed as a virtual server using the Open Virtualization Format (OVF) standard for packaging and distributing virtual appliances that run in a virtual environment. It requires VMware vSphere as the hypervisor. Cisco publishes the distribution as an OVF file with the file extension .OVA, which stands for Open Virtual Appliance. This file contains the OVF template for the application. The OVF template defines the virtual machine’s hardware and is preloaded with required software.

Hardware and System Requirements

  • A server platform that meets VMware’s Compatibility Guide for VMware vSphere 5.1 or later is required. The Cisco Jabber Guest virtual machine uses a 64-bit distribution of CentOS 6.10. Make sure that the server platform uses CPUs that are capable of 64-bit instructions.

  • Cisco Jabber Guest Server is supported on any Full UC Performance CPU, beginning with Intel Xeon Processor 5600 with a minimum physical core speed of 2.53 GHz or higher and any Restricted UC Performance CPU, beginning with Intel Xeon Processor E5 2609 v1 with a minimum physical core speed of 2.4 GHz or higher. For more information on Full UC performance CPUs and Restricted UC Performance CPUs, see the Processors/CPUs section in UC Virtualization Supported Hardware.

  • Cisco Jabber Guest is allowed on server models meeting required specifications, including Cisco Business Edition 6000 (BE6000), Cisco Business Edition 7000 (BE7000), and UC on UCS Tested Reference Configurations with a Full UC Performance CPU. BE6000M (M2) UCS C200 M2 TRC#1 is not supported. For more information, see Virtualization for Cisco Jabber Guest Server. Cisco Jabber Guest Server must follow the application co-residency and virtual-to-physical sizing rules in the Unified Communications Virtualization Sizing Guidelines.

  • Cisco Jabber Guest supports all virtualization software described in Purchasing/Sourcing Options for Required Virtualization Software.

  • If Cisco Jabber Guest Server is installed on a Cisco Business Edition 6000 server or Cisco Business Edition 7000 server, it must follow the additional co-residency rules in the Cisco Business Edition 6000 and Cisco Business Edition 7000 Co-residency Policy Requirements.

  • See the VMware developer documentation for additional configuration and hardware requirements. We highly recommend using the Cisco Unified Computing System (CUCS) to simplify and maximize performance.

Cisco Jabber Guest Plug-in Requirement

The Cisco Jabber Guest solution includes a browser plug-in that is downloaded and installed by the caller on the local machine. For Google Chrome and Firefox (50 and later), the web page prompts the user to install the Chrome/Firefox Extension and the Cisco Jabber Guest Add-on. For all other browsers, the Cisco Jabber Guest web page prompts the caller to download and install the plug-in the first time the service is used.

New plug-ins are periodically made available with fixes and new functionality. The caller is prompted to download and install the new plug-in the next time an attempt is made to place a call.

Call Session Capacity

Call Session Capacity (Cisco Expressway)

The maximum number of Cisco Jabber Guest sessions that can be supported through the Cisco Expressway depends on the type of appliance/VM server, and whether Cisco Expressway-C and Cisco Expressway-E are deployed as a single pair or as clusters.

Each session typically uses 4 TURN server relays on the Cisco Expressway-E.

Each Cisco Jabber Guest call session is a video session, from the perspective of Cisco Expressway, even if video is disabled during the call.

Call Session Capacity (Cisco TelePresence Video Communication Server)

The maximum number of Cisco Jabber Guest sessions that can be supported through the Cisco TelePresence Video Communication Server depends on the type of appliance/VM server, and whether Cisco VCS-C and Cisco VCS-E are deployed as a single pair or clusters.

Each Cisco Jabber Guest call session is a video session, from the perspective of Cisco VCS, even if video is disabled during the call.

Emergency Service Calls

Do not use Cisco Jabber Guest for emergency services calls. Do not configure Cisco Jabber Guest to route calls through the public switched telephone network (PSTN) to an emergency response center. If you do, calls may be misdirected to the wrong emergency response center or the emergency response center may make errors when determining your location.

Mac OS X (v10.11.1 and v10.11.2) Limitation: Video Display Always on Top of Other Windows in Chrome

When you use the Jabber Guest add-on for Chrome with Mac OS X El Capitan (v10.11.1 or v10.11.2), the video frame stays on top of other windows.

The workaround is to use either of the following browsers:

  • Mozilla Firefox

    or

  • Safari

Or upgrade to the Apple Mac OS X El Capitan version 10.11.3 and then restart.

Caveats

Bug Severity Levels

Known defects, or bugs, have a severity level that indicates the priority of the defect.

Severity Level

Description

1 Catastrophic

Reasonably common circumstances cause the entire system to fail, or a major subsystem to stop working, or other devices on the network to be disrupted. No workarounds exist.

2 Severe

Important functions are unusable and workarounds do not exist. Other functions and the rest of the network is operating normally.

3 Moderate

Failures occur in unusual circumstances, or minor features do not work at all, or other failures occur but low-impact workarounds exist.

This is the highest level for documentation bugs.

4 Minor

Failures occur under very unusual circumstances, but operation essentially recovers without intervention. Users do not need to install any workarounds and performance impact is tolerable.

5 Cosmetic

Defects do not cause any detrimental effect on system functionality.

6 Enhancement

Requests for new functionality or feature improvements.
