Hello,
I'm having troubles trying to figure out how to work with one of my
providers. They require that Contact be the specific address of my
server for authorization, however, Contact is always the address of
the UAC initiating the call. I've tried to use
subst('/^Contact:(.*)sip:[^@]*@[a-zA-Z0-9.]*:[0-9]+(.*)$/Contact:\1sip:2345550000@1.2.3.4:5060\2/i');
and this works until a reinvite or a BYE is received. Kamailio follows
the contact and sends it back to 1.2.3.4 like it's supposed to and
loops around and around until max forwards is hit.
Has anybody tackled this before or have any suggestions?
to be short, I could say:
drop the provider. It is clear will loop as
you replace the address of UA with the address of the proxy.
As solutions:
- use a b2bua in front of that provider (asterisk, freeswitch)
- add a parameter to contact address uri (e.g., target) and you do
script operations to recover it.
Cheers,
Daniel
