[asterisk-users] PJSIP and Kamailio without registration

[Chirag Desai]

OK, it stopped working.

It turns out the transport and endpoints in PJSIP are ok. I can send an
invite from my unregistered snom phone and I can see some activity in the
CLI.

However, when I dial from my snom to Kamailio and have it pass the message
to asterisk, PJSIP seems to ignore the sip messages even though they are
there.

Is there something wrong in the invite that I'm missing?

Ideas greatly appreciated.
