Network Requirements

When using Cisco Jabber over your corporate Wi-Fi network, we recommend that you do the following:

  • Design your Wi-Fi network to eliminate gaps in coverage as much as possible, including in areas such as elevators, stairways, and outside corridors.

  • Ensure that all access points assign the same IP address to the mobile device. Calls are dropped if the IP address changes during the call.

  • Ensure that all access points have the same service set identifier (SSID). Hand-off may be much slower if the SSIDs do not match.

  • Ensure that all access points broadcast their SSID. If the access points do not broadcast their SSID, the mobile device may prompt the user to join another Wi-Fi network, which interrupts the call.

  • Ensure that the Enterprise firewall is configured to allow the passage of Session Traversal Utilities for NAT (STUN) packets.

Conduct a thorough site survey to minimize network problems that could affect voice quality. We recommend that you do the following:

  • Verify nonoverlapping channel configurations, access point coverage, and required data and traffic rates.

  • Eliminate rogue access points.

  • Identify and mitigate the impact of potential interference sources.

For more information, see the following documentation:

  • The "VoWLAN Design Recommendations" section in the Enterprise Mobility Design Guide.

  • The Cisco Unified Wireless IP Phone 7925G Deployment Guide.

  • The Capacity Coverage & Deployment Considerations for IEEE 802.11g white paper.

  • The Solutions Reference Network Design (SRND) for your Cisco Unified Communications Manager release.

IPv6 Requirements

Cisco Jabber is fully IPv6 ready, it works as normal in pure IPv6 and hybrid networks with the limitations listed in this section. Cisco Collaboration solutions does not currently fully support IPv6. For example, Cisco VCS Expressway for Mobile and Remote Access has limitations in pure IPv6 networks that require NAT64/DNS64 to be deployed in mobile carrier networks. Cisco Unified Communications Manager and Cisco Unified Communications Manager IM and Presence don't currently support HTTPS in pure IPv6 networks.

This feature is configured in Jabber using the IP_Mode parameter to set the protocol to IPv4, IPv6, or Dual Stacks. Dual Stacks is the default setting. The IP_Mode parameter can be included in Jabber Client Configuration (refer to the latest version of the Parameters Reference Guide for Cisco Jabber), the bootstrap for Windows, and the URL configuration for Mac and Mobile clients.

The network IP protocol used by Jabber when connecting to services is determined by the following factors:

  • The Jabber Client Configuration IP_Mode parameter.

  • The client operating system IP capabilities.

  • The server operating system IP capabilities.

  • The availability of a DNS record for IPv4 and IPv6.

  • Cisco Unified Communications Manager SIP setting for softphone devices configuration for IPv4, IPv6, or both. The SIP connection setting for softphone devices must match the Jabber IP_Mode parameter setting to make a successful connection.

  • Underlying network IP capabilities.

On Cisco Unified Communications Manager, the IP capability is determined by generic server settings and device-specific settings. The following table lists the expected Jabber connections given the various settings, this list assumes that the DNS records for IPv4 and IPv6 are both configured.

When the Client OS, Server OS, and Jabber IP_Mode parameter are set to Two Stacks, Jabber will use either IPv4 or IPv6 address for connections with the server in accordance with RFC6555.

When you use Jabber in IPv6-Only mode, NAT64/DNS64 is required to connect to an IPv4 infrastructure, such as Webex Messenger service, Cisco VCS Expressway for Mobile and Remote Access, and Cisco Webex Platform service.

Desktop device support is available for IPv6-only on-premises deployments. All Jabber mobile devices must be configured as Two Stacks.

For more details about IPv6 deployment, see the IPv6 Deployment Guide for Cisco Collaboration Systems Release 12.0.

Limitations

  • HTTPS Connectivity

    • In an On-Premises deployment, Cisco Jabber supports IPv4 only and Two Stacks modes to connect to Cisco Unified Communications Manager and Cisco Unified Communications Manager IM and Presence Service. These servers do not currently support IPv6 HTTPS connections.

      Cisco Jabber can connect using HTTPS to Cisco Unity Connection for Voicemail using IPv6 only mode.

  • Webex Messenger Limitations

    • Webex Messenger is not supported on IPv6.

  • Telephony Limitations

    • When you upgrade user devices on Cisco Unified Communications Manager to either Two Stacks or IPv6 only, the corresponding Jabber client must be upgraded to 11.6 or later.

    • When an installation includes IPv4 endpoints and IPv6 endpoints, we recommend that you use a hardware MTP to bridge the Audio and Video between these devices. This is supported on hardware MTP with Cisco IOS version 15.5. For example, a Cisco 3945 router must run the following T-train build: c3900e-universalk9-mz.SPA.155-2.T2.bin.

    • At present we do not have a solution roadmap to support IPv4 and IPv6 simultaneously in Cisco endpoints including Jabber. Cisco Unified Communications Manager supports the current functionality which is IPv4-Only and IPv6-Only. An MTP is required to support calls between IPv4-only and IPv6-only endpoints, or IPv4-only or IPv6-only Gateways.

    • Jabber to Jabber calls are not supported on IPv6.

  • File Transfer Limitations

    • Advanced File Transfer—When the client is configured for Two Stacks and Cisco Unified Communications Manager IM and Presence Service is Two Stacks enabled, advanced file transfer is supported on the following Cisco Unified Communications Manager IM and Presence Service versions:

      • 10.5.2 SU2

      • 11.0.1 SU2

      • 11.5

    • Person to Person file transfer—For on-premises deployment person to person file transfer between IPv4 and IPv6 clients is not supported. If you have a network configuration with both IPv4 and IPv6 clients, we recommend configuring advanced file transfer.

  • Mobile and Remote Access Limitations

    • Cisco VCS Expressway for Mobile and Remote Access doesn't support IPv6.

    • If Cisco Unified Communications Manager is configured for an IPv6 SIP connection, you can't connect to Cisco Unified Communications Manager using Cisco VCS Expressway for Mobile and Remote Access to use telephony services.

Audio and Video Performance Reference


Attention

The following data is based on testing in a lab environment. This data is intended to provide an idea of what you can expect in terms of bandwidth usage. The content in this topic is not intended to be exhaustive or to reflect all media scenarios that might affect bandwidth usage.

Media Assure

Ensure quality of real-time media on all network types so that your meetings aren’t interrupted because of poor media quality. Media Assure can relieve up to 25% packet loss.

Media Assure is supported for video on Cisco Unified Communications Manager Release 10.x or later and for audio and video on Cisco Unified Communications Manager Release 11.5 or later.

For Expressway for Mobile and Remote Access deployments, Media Assure requires Cisco Expressway Release 8.8.1 or later.

For minor to severe network conditions Jabber can:

  • Temporarily limit bandwidth on streams.

  • Re-sync video.

  • Pace packets to avoid unnecessary congestion based burst losses.

  • Provide resilience mechanisms by using upfront SDP signaling from first media packet.

  • Protect packet loss.

  • Avoid congestion based loss because of over production of media.

  • Improve protection of low frame rate / low bit rate streams.

  • Support authenticated and encrypted FEC.

Fast Lane Support

Fast Lane support ensures that business critical applications are prioritized on the network, even during high traffic. Jabber supports Fast Lane for Voice and Video traffic. For iOS 10, when the access point (AP) fast lane feature is used, the DSCP value configured on Cisco Unified Communications Manager will not be used anymore; whereas for iOS 9 version or iOS 10 that does not support the fast lane feature, Jabber will continue using the DSCP value configured on Cisco Unified Communications Manager.

Irrespective of the DSCP configuration on Cisco Unified Communications Manager, if your wireless AP supports the fast lane feature, then Jabber automatically sets the following DSCP and user priority (UP) values:

  • For audio calls or the audio portion in a video call, DSCP is set to 0x2e and UP is set to 6.

  • For the video portion in a video call, DSCP is set to 0x22 and UP is set to 5.

  • If your AP does not support fast lane or does not use it, DSCP values are automatically set to that designated by Cisco Unified Communications Manager.

Prerequisites:

  • WLC running AireOS 8.3 and higher

  • AP1600/2600 Series Access Points, AP1700/2700 Series Access Points, AP3500 Series Access Points, AP3600 Series Access Points + 11ac Module, WSM, Hyperlocation module, 3602P, AP3700 Series Access Points + WSM, 3702P, OEAP600 Series OfficeExtend Access Points, AP700 Series Access Points, AP700W Series Access Points, AP1530 Series Access Points, AP1550 Series Access Points, AP1570 Series Access Points, and AP1040/1140/1260 Series Access Points

Video Rate Adaptation

Cisco Jabber uses video rate adaptation to negotiate optimum video quality. Video rate adaptation dynamically increases or decreases video bit rate throughput to handle real-time variations on available IP path bandwidth.

Cisco Jabber users should expect video calls to begin at lower resolution and scale upwards to higher resolution over a short period of time. Cisco Jabber saves history so that subsequent video calls should begin at the optimal resolution.

Call Management Records

At the end of a call, Jabber sends call performance and quality information to Cisco Unified Communications Manager. Cisco Unified Communications Manager uses these metrics to populate the Cisco Unified Communications Manager Call Management Record (CMR). Cisco Jabber sends the following information for both audio and video calls:

  • Number of packets sent and received.

  • Number of octets sent and received.

  • Number of packets lost.

  • Average jitter.

The client also sends the following video specific information:

  • Codec sent and received.

  • Resolution sent and received.

  • Framerate sent and received.

  • Average round-trip time (RTT)

The client sends the following audio specific information:

  • Concealed seconds.

  • Severely concealed seconds.

The metrics appear in the Cisco Unified Communications Manager CMR record output in plain text format, this data can be read directly or consumed by a telemetry or analytics application.

For more information about configuring Cisco Unified Communications Manager CMR records, see the Call Management Records chapter of the Call Detail Records Administration Guide for your release of Cisco Unified Communications Manager.
