[pjsip] SIP REGISTER problem encountered in symbian build

Dear Benny,

You advice is very helpful. I add the below line to ua.cpp:
cfg.allow_contact_rewrite = PJ_FALSE;

This disables the registration update due to contact being different
from ip-addr/port values in Via. Thanks so much.

Alex.

Hi Alex,

Since release 0.8.0, we have a feature to automatically update the
registration if the Contact address is different than the Via
received/rport value. Have a look at
http://trac.pjsip.org/repos/ticket/381

This works fine with most servers so far, and it should. Could it be
that your server doesn't like this?

Cheers
 Benny
