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."

Advanced Setup Method
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
SIP request.
2. User agent server (UAS) - A server application that contacts the
user when a SIP request is received and that returns a response
on behalf of the user.
Typically, an SIP end point is capable of functioning as both a UAC
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
provider.
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.
