[Users] Query on Registration

[Vivek Bhat]

Thanks Ohad, Samuel. t_replicate worked fine. 

However, I faced one another problem.

If the Via header from UAC contains "rport" parameter,
then, removing Via header before calling t_replicate()
still adds the rport parameter with the value in the
newly added Via from Openser. Also, it doesn't add
"\r\n" to the new Via header, thereby, the next header
field concatanates with the Via header as below:

Here is the REGISTER received from openser using
t_replicate() function: 
-----------------------------------------------------------------------------------------------

Received from 172.16.13.100:5061 (UDP) the following
SIP message
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

--------------------------------------

Note that Original "Via" is removed using remove_hf()
function before calling t_replicate. But, still
"rport" parameter is appended to the new "Via" header.
Also, the next header "Contact" is concatanated with
Via. 

Please advice how to avoid "rport" being appended?

Thanks,
Vivek
