Subject: Re: [Users] mediaproxy working, but not if asterisk is involved
To: daniel(a)voice-system.ro
the problem is that I don't even see the "reply received"... So for some
reason the asterisk reply isn't passed through to the onreply_route. My
theory is that asterisk doesn't respect the reply parameters somewhere, but
it isn't clear to me where

Do you get "using mediaproxy" message in the logs? If not, that the
search() matches, I cannot sot right now what is wrong with the
expression. But you can move t_on_reply("1") into
if*method=="INVITE")
statement and replace the search condition with if (status =~
"(183)|(2[0-9][0-9])").
See:

below is the transaction of the failed mediaproxy
invite. I allready
could tell that replies go through openser, but I don't see the reason
why ser doesn't see them as replies (and use the mediaproxy function).
as you can see, the invite from <ip client> to <ip asterisk> (through
<ip OPENSER>, which is also ip of mediaproxy) goes in one direction
good (the ip in the SDP is changed from <ip client> to <ip openser>,
but the return path en the OK (with it's SDP) is not changed
I did a tcpdump with a call between 2 clients, where the proxy works,
and the only difference I see is that in the reply of asterisk, there
is no rinstance field in the contact header

Hello,
watch the network traffic with ngrep on your sip server. You can
see the
call flow which may help to identify the issue. You can paste it
to the
list and someone may give you hints.
Cheers,
Daniel

asterisk

but the SDP towards the calling phone is not

am I missing something here?
