Cisco Adaptive Security Appliance (Optional)

VPN On Demand (Optional)

The Apple iOS On-Demand VPN feature requires certificate-only authentication. If you set up the a (ASA) without certificate-only authentication, the user must manually initiate the AnyConnect VPN connection as needed.

The iOS device must be able to access the corporate network, servers, and telephony endpoints using a VPN client, such as Cisco AnyConnect Secure Mobility Client.

Cisco AnyConnect Secure Mobility Client Integration (Optional)

• iOS devices must run Cisco AnyConnect Secure Mobility Client Version 3.0.09115, which is available from the Apple App Store
• Cisco ASA 5500 Series Adaptive Security Appliance (ASA) Version 8.4(1) or later
• Cisco Adaptive Security Device Manager (ASDM) Version 6.4 or later
• ASA license requirements: Use one of the following combinations:
  • AnyConnect Essentials and AnyConnect Mobile licenses
  • AnyConnect Premium and AnyConnect Mobile licenses
  For more information about Cisco AnyConnect license requirements, see VPN License and Feature Compatibility.
• Certificate Authority (CA) if using certificate-based authentication: Cisco IOS Certificate Server, Cisco IOS Certificate Server or Microsoft Windows Server 2003 Enterprise Certificate Authority

Cisco Jabber for iPhone and iPad supports the following cloud-based servers:

• Cisco WebEx Messenger Release 7.5 or later
• Cisco WebEx Administration Tool Release 7.5
• Cisco WebEx Meeting Center as follows:
  • Version T26L with Service Pack 20
  • Version T27L with Service Pack 9

You can use the following directory servers with Cisco Jabber for iPhone and iPad.

Screen Readers

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.

Assistive Touch

You can navigate Cisco Jabber for iPhone and iPad using Assistive Touch.

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.

Note	There are no TCP/IP services enabled in the client.

The following table describes bit rates for audio:

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.

Audio

The client uses the maximum audio bit rate.

Interactive Video

The client allocates the remaining bit rate as follows: The maximum video call bit rate minus the audio bit rate.

Note that VPN increases the size of the payload, which increases the bandwidth consumption.

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.

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.
