The peers in a session are called User Agents (UAs). A user agent can function in one of the following roles: 1. User agent client (UAC) - A client application that initiates the 2 SIP request. 2. User agent server (UAS) - A server application that contacts the 3 user when a SIP request is received and that returns a response on behalf of the user. 4 Typically, a SIP end point is capable of functioning as both a UAC and a UAS, but functions only as one or the other per transaction. 5 Phone standards vary internationally and from provider to provider, so it is important that the VoIP router is configured correctly for your provider. 6 Codecs are used to convert an analog voice signal to digitally encoded version. Codecs vary in the sound quality, the bandwidth 7 required, the computational requirements, etc. You can specify which audio coding process you would like to use. There are four voice codecs supported by the VoIP router, you may try different settings to determine the best audio quality you obtain from the combination of your network connection and your used audio device (head set or hand set). The default codec sequence is listed below. You can use the Up and Down buttons to change priority. 1. G.729 2. G.723.1 3. G.711 U law 4.
