Cisco Jabber for iPhone and iPad is compatible with the VoiceOver screen reader. Users who require screen readers should always use the most recent version to ensure the best possible user experience.
You can navigate Cisco Jabber for iPhone and iPad using Assistive Touch.
Supported Audio Codecs
Minimum requirement for low-bandwidth availability: G.729a.
Users can turn Low Bandwidth mode on and off in the client settings if they experience voice quality issues.
Normal mode supports G.711 and G.729a.
Low Bandwidth mode supports G.729a only.
Supported Video Codecs
Supported Voicemail Codecs
G.711 mu-law (default)
Cisco does not support visual voicemail with G.729. However, users can access their voice messages using G.729 and the Call Voicemail feature.
If you deploy Phone Services, the mobile device must be able to connect to the corporate network using voice-ready Wi-Fi.
For optimal user experience when using Cisco Jabber over your corporate Wi-Fi network, Cisco recommends that you:
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 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.
Conduct a thorough site survey to minimize network problems that could affect voice quality. Cisco recommends that you:
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.

Bluetooth use can cause voice quality and connectivity issues.
If users connect to the network remotely, the mobile device must be able to connect to the corporate network using a solid, high-bandwidth VPN connection. Video and audio quality is dependent on connection quality and cannot be guaranteed.
The client uses the ports and protocols listed in the following table. If you plan to deploy a firewall between the client and a server, you must configure the firewall to allow these ports and protocols.
There are no TCP/IP services enabled in the client.

Audio and Video Performance Reference
Learn about audio and video performance for Cisco Jabber for iPhone and iPad.
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.
The following table describes bit rates for audio:
Codec bit rate (kbits per second)
Network Bandwidth Utilized (kbits per second)
Bit Rates for Video
The following table describes bit rates for video with G.711 audio:
Bit rate (kbits per second) with g.711 audio
256 x 144
512 x 288
640 x 360
Notes about the preceding table:
The client captures and transmits at 20 fps.
The values in this table do not include audio.
Maximum Negotiated Bit Rate
You specify the maximum payload bit rate in Cisco Unified Communications Manager in the Region Configuration window. This maximum payload bit rate does not include packet overhead, so the actual bit rate used is higher than the maximum payload bit rate you specify.
The client uses the maximum audio bit rate.
The client allocates the remaining bit rate as follows: The maximum video call bit rate minus the audio bit rate.
Performance Expectations for Bandwidth
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:
Audio + Interactive Video (Main Video)
125 kbps under VPN
At bandwidth threshold for g.711. Insufficient bandwidth for video.
Sufficient bandwidth for g.729a and g.722.1.
Insufficient bandwidth for video.
Sufficient bandwidth for any audio codec.
256 x144 at 20 fps
Sufficient bandwidth for any audio codec.
640 x 360 at 20 fps
Note that VPN increases the size of the payload, which increases the bandwidth consumption.
Video Rate Adaption
The client 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.
Users should expect video calls to begin at lower resolution and scale upwards to higher resolution over a short period of time. The client saves history so that subsequent video calls should begin at the optimal resolution.
Quality of Service Configuration
Review the supported methods to configure Quality of Service (QoS) for the client.
Port Ranges on Cisco Unified Communications Manager
Cisco Unified Communications Manager lets you define one port range for the client. The client divides this port range equally and uses the lower half for audio calls and the upper half for video calls. For example, you define a port range of 1000 to 3000 in Cisco Unified Communications Manager. The client uses a port range of 1000 to 2000 for audio calls and a port range of 2000 to 3000 for video calls.
To access the SIP Profile Configuration window, select Device > Device Settings > SIP Profile.
The Start Media Port field defines the lowest port available to the client. The Stop Media Port field defines the highest port available. See the SIP Profile Configuration topic in the Cisco Unified Communications Manager documentation for more information.
