Bandwidth Performance Expectations for Cisco Jabber for iPhone and iPad
The client separates the bit rate for audio and then divides the remaining bandwidth equally between interactive video and
presentation video. The following table provides information to help you understand what performance you should be able to
achieve per bandwidth.

Note that VPN increases the size of the payload, which increases the bandwidth consumption. VPN is commonly used for LTE on
the public network. Traffic across a private LTE network (such as Verizon MPN) is separated from the public Internet.

If applications in addition to Cisco Jabber will benefit from preferential treatment by PNTM, the 2Mbps option may be
beneficial. Although the maximum bit rate used for Jabber calling can be configured, other data application may not be
controlled. In addition, the mobile device may not have the ability to closely control priorization of voice/video traffic over
data traffic within the device itself.
Design considerations for CUCM and LTE-connected Jabber clients
If the PNTM service rate chosen is 0.5Mbps, it is feasible for the bandwidth used by a Mobile client with Cisco Jabber to
exceed it. This is not desirable, as the traffic above the service rate will be dropped, affecting audio and video call quality.
Cisco Unified Communications can be configured to limit the maximum bandwidth used by a particular mobile client for
voice and video calling. This ability exists whether the device part of a premises-based call control system, or leverages a
cloud-based unified communications service such as Verizon’s Unified Communications and Collaboration as a Service
offering. www.verizonenterprise.com/pro

Two Cisco Unified Communications functions that work together are Locations (call admission control, the maximum
number of simultaneous calls from a location based on bandwidth) and Regions (defining the maximum per-call audio and
video bandwidth from an endpoint). As each LTE mobile device has its own network connection, Locations would not be
used as a call admission control technique. In other words, including an organization’s LTE mobile devices in one UC
“Location” and then limiting the maximum # of calls would not be beneficial.
Regions are useful as a method to determine the maximum bandwidth per user on a call. An LTE mobile device can be
defined in a Cisco UC Region that can limit the maximum bandwdith per call for both audio and video communications.
Based on those limitations, the endpoint will use the best audio and video codec that it can support, and that will yield a bit
rate within the defined limits. An example would be to create two Regions for mobile video devices, one for devices
leveraging 2Mbps PNTM and one for device using 0.5Mbps PNTM service rate.
