Advanced Setup Method redirect servers receive requests from a client and decide where to send these requests. Proxy servers can provide functions such as authentication, authorization, network access control, routing, reliable request retransmission, and security. From the SIP RFC, "A registrar is a server that accepts REGISTER requests and places the information it receives in those requests into the location service for the domain it handles." See below for a description of the parameters. Parameter Description SIP Listen Port: It is strongly recommended that you to leave the SIP port unchanged (Default: 5060). Proxy Setting set the proxy settings. • Proxy IP: IP address of your proxy server. (From your VoIP provider) • Proxy Port: Port number of the proxy server. (From your VoIP provider) Registrar Setting set the registrar settings. • Registrar IP: IP address of SIP registrar. • Registrar Port: Port number of SIP registrar. VoIP Advanced Setting Configure the VoIP advanced settings on this page, and click "OK." 68 Advanced Setup Method 1 SIP is a peer-to-peer protocol. 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, an SIP end point is capable of functioning as both a UAC 5 and a UAS, but functions only as one or the other per transaction. Phone standards vary internationally and from provider to provider, so it is important that the VoIP router is configured correctly for your 6 provider. 7 Codecs are used to convert an analog voice signal to digitally encoded version. Codecs vary in the sound quality, the bandwidth 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.711 A law 2. G.711 U law 3. G.729 4.
