Hallo everyone,

I have installed CW 1.2.1 from SVN r5631 successfully. Tested RxFAX and TxFAX and both works like a charm with g729 and alaw!

However I'm having some difficulty with T38Gateway. Path is: PSTN --> CW --> SIP ATA --> fax machine

1.) One as soon as call is answered, I get :

WARNING[1122613568]: dsp.c:595 cw_dsp_process: Tone detection is not supported on codec g729. Use RFC2833

2.) Call is answered and UDPTL transfer starts and CW crashes:


Feb 13 11:55:55 VERBOSE[1098680640] logger.c: Got UDPTL packet from XX.XXX.X.X:4282 (len 49)

Feb 13 11:55:55 NOTICE[1098680640] udptl.c: UDPTL Transmission error to 10.211.15.119:14002: Message too long

PS: I replace IP address with XX.XXX.X.X for security reasons.

Any assistance would be greatly appreciated.

Thanks in advance!

Do you get a core file for debugging ? Can you post a backtrace ?

Regards

Hans
