Hello all. I’m very glad to connect to asterisk community.
Now i trying to deploy new asterisk server in our company and faced with fax-problem on chan_ooh323. This test maded in local environment with quintum tenor DX2060, but i tried with external h323 provider and got the same result.
I tried to change ooh323.conf parameters: directmedia, directrtpsetup, faststart, mediaforconnect, faxtdetect - no result. Bug is stable.
I tried this test on many Asterisk 11 branches and last SVN trunk - in all bulids it not working properly.
In Asterisk 10.9 it working the same, but udp sockets closes properly after RTP-timeout call crash.
Please help me find problem. What i forgot to check ?
When I start SendFAX I get error after ooh323-rtptimeout time if value of this time less than time of fax sending:

If I increase rtptimeout in ooh323.conf greater than time of sending (f.e. 300sec) fax sending finish successfully but udp sockets still remain opened.
