Hi Ruud,
I'm working now on t.38 fax with opensips 1.4.3 + mediaproxy 2.3.1 and
I have the same problem as Jeff.
Here's my scenario.
I have a fax connected to a patton (sip number 1004) with a private ip
(192.168.1.253) and a hylafax/t38modem (sip number 08321111) with a
public ip (IP_T38MODEM).
Calls are established at g711, proxied with engage_media_proxy() (all
is ok as i can see, the c=line has the media-relay ip), but when there
is a re-invite for t38 the media is not proxied and the packets have
c=line with original ip (private and public) (In this way t38modem
sends packets to the private ip...). There's no "image" media type in
syslog.
The problem is in both ways (patton to t38modem and t38modem to
patton). If the patton has the public ip all works fine.
I have some logs. I hope these information can be useful for you
(sorry for the length :-)):
Thanks and Regards,
Carlo Dimaggio
