[Users] Commercial SIP Server

[Daniel-Constantin Mierla]

It is a bit tough. There are some special headers added, but they can be 
changed or removed (e.g., server, warning). If you have an account to 
that server, it is easier, because you can watch traffic in a call. 
Early versions of openser used same phrase in 100 reply from TM. Now 
they are different, but not the "Trying" as in RFC.

Also, building branch value in ACK is different in specific situations. 
I d not remember all differences, but with a bit investigation some 
criteria can be found.

Cheers,
Daniel
