6. Using sip proxies and registrar.

Registering on a SIP server can be usefull in two main cases:

With linphone=1.0.0 you can choose to use several proxies simultaneously. Go to the property box, section sip, and click on add proxy. You'll be prompted for proxy address, route and your identity (also known as address of record). This information should be given to you by your sip provider you registered to. Route can be optionnal, so leave it empty in case you don't know what to put here. The identity is the sip address you are known by the proxy. Other users on the network are supposed to always be able to find you at this sip address.
