Hello,
the r-uri is not rewritten with ip address of the phone, I guess you
don't use user location to locate the phone. Is the phone registered to
kamailio?
You say about the code for re-invites where you have a t_relay with
outbound proxy. Normally, that should go via record-routing. If that
code is also for initial invites and you must do it in this way, then
you need to rewrite the r-uri domain and port to match phone's ip and port.
I suggest you use kamailio 3.0.x with default config file. It is easy to
enable features such as authentication and use location. Create accounts
for you phones, set them to register to kamailio and make calls. Then
adapt the config to meet extra needs you may have.
Cheers,
Daniel
