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, so it is important that the Belgacom b-box is configured

for the correct country.

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

Belgacom b-box, 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.
