Cameron,
I'm pussled by your error:
SIP/2.0 500 I'm terribly sorry, server error occurred (1/SL)
that comes *before* you send the message to Asterisk. Hopefully you have
been able to get log messages in messages by now (your ser.cfg had
log_stderror=yes, which is probably why you didn't get anything). If not,
try changing ser.cfg to
debug=7
fork=no
log_stderror=yes
and then start ser with 'ser' (not serctl).
Also, as you say, it seems that Asterisk does not challenge SER. Your
provider should be able to tell you the format of the ruri required to get a
challenge.

I am trying the get the uac module working with the
onsip.org ser.cfg
(the pstn + mediaproxy version). I think the problem is related to the
authentication on the gateway device. It doesn't seem to be
challenging SER. Below is the SIP traffic and then the ser.cfg file. Any
suggestions
would be appreciated. For information, the gateway (198.22.67.70) is
provided by Nufone.net and is an Asterisk server, I believe.
Thanks in advance for any advice.
Regards
Cameron
