[sr-dev] UAC module - got sip response 200 while registering

[Daniel-Constantin Mierla]

The change done by registrar server to the Contact URI is not compliant
-- the address has to stay what the UA has set. Otherwise a lot of
multi-line SIP phones won't work.

The user part of the Contact in the REGISTER generated by uac module is
used to match the local user details. If the user part is changed then
it is not going to be a match when a call comes in with the modified
Contact address in the R-URI.

Cheers,
Daniel
