[OpenSIPS-Users] topology hiding and contact header

[Bogdan-Andrei Iancu]

Hi Brett,

1) a SIP URI without username is perfect valid.

2) as Contact URI is just for IP routing purposes, a username part is 
totally useless.

3) preserving the username may "leak" topo info (you never know what is 
the username content).

4) see the simple attached patch to force a static dummy username.
