Bias-Free Language

For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Support for SIP Video Calls with Flow Around Media

This feature provides the ability to have a SIP video call where the media flows around the Cisco Unified Border Element (Cisco UBE) and the Cisco Unified Border Element (Enterprise) platform. Previous support was only for call scenarios where the media flowed through the Cisco UBE.

Prerequisites

Cisco Unified Border Element

•Cisco IOS Release 12.4(15)XZ or a later release must be installed and running on your Cisco Unified Border Element.

Cisco Unified Border Element (Enterprise)

•Cisco IOS XE Release 3.1S or a later release must be installed and running on your Cisco ASR 1000 Series Router.

Restrictions

•Media flow-around for Delayed-Offer to Early-Offer audio and video calls is not supported.

How to Configure Support for SIP Video Calls with Flow Around Media

To enable this feature so that media packets pass directly between endpoints without the intervention of the Cisco UBE, use the media command in dial peer, voice class, or voice service configuration mode. For detailed information on the use of this command, see the Cisco IOS Voice Command Reference.
