Hi Bastin,
probably there is kind of a RTP deadlock between the RTPproxy and OpenPBX - both are waiting for the other party to send the media before sending on its turn.
try something like: if (nat_uac_test("8")) { force_rtp_proxy(); } else { force_rtp_proxy("r"); }
refer to http://www.openser.org/docs/modules/1.2.x/nathelper.html for more details.
regards, bogdan

Hi everybody,
I've got a question: Does anybody get T.38 working between OpenPBX and OpenSER + RTPProxy?
The following scenarios are working fine:
1: SIP-FAX1 (pub. IP) <-> OpenPBX <-> SIP-FAX2 (pub. IP) 2: SIP-FAX1 (NAT) <-> RTPProxy+OpenSER <-> SIP-FAX2 (pub. IP) 3: SIP-FAX1 (NAT) <-> RTPProxy+OpenSER <-> SIP-FAX2 (NAT) 4: SIP-FAX1 (pub. IP) <-> OpenSER <-> OpenPBX <-> SIP-FAX2 (pub. IP)
But the following scenario is not working:
SIP-FAX1 (NAT) <-> RTPProxy+OpenSER <-> OpenPBX <-> SIP-FAX2 (pub. IP)
It seems to be that the RTPproxy has a problem with the OpenPBX but no Problem with SIP-FAX-ATAs.
Does anybody have an idea what's going wrong???
Cheers Bastian
