Components Used
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
SIP user agents (UA) for TelePresence

A SIP user agent (UA) is a logical network end-point used to create or receive SIP messages and thereby manage a SIP session. A SIP UA can perform the role of a User Agent Client (UAC), which sends SIP requests, and the User Agent Server (UAS), which receives the requests and returns a SIP response. These roles of UAC and UAS only last for the duration of a SIP transaction.

These are referenced in RFC3261 and RFC6011 “

Every SIP user agent (phone, software, device) identifies itself with a string. The syntax of this string is not defined, but a common practice is <vendor> <product> <firmware version>

Below is an example of the “User-Agent” ID in use in the SDP payload.
User-Agent: TANDBERG/518 (TCNC6.2.0.20b1616)
Supported: replaces,timer,gruu,path,outbound
