You can try FaxDetect application to detect fax tones and you can use SipT38SwitchOver() application to FORCE the switchover to t38 mode. Unfortunately i think that this problem depends mostly on the other party fax (or ATA). Anyway to have a look at this problem, you should help us to debug: * Add |debug flag to TxFax * open logger.conf in the openpbx config dir and uncomment the line beginning with "full => " * start openpbx and from the CLI type: * sip debug * udptl debug * rtp debug * set verbose 9 * set debug 9 Preparing for the call, use tethereal or tshark or tcpdump to sniff the traffic and save it on a file. Those applications are quite complex but something like the following may work: * $application -i $ETH_IF -n host $REMOTE_HOST_OPENPBX_IS_TALKING_TOO -s65000 -w $FILENAME where : * $application is tcpdump, tethereal or tshark * ETH_IF is the interface (if only one, you may skip it) * $REMOTE_.... is self explaining * $FILENAME the dump file Now try the call and at the end, stop $application and sava the dump file. Open the full log in openpbx dir, take the intresting parts out (if there other calls in the meanwhile, please try to tidy the log) Put those 2 files somewhere and tell us where to grab them (you may even post those logs to the list if you cannot put those files online). Max P.S.: Can please someone update the wiki to ad those debug informations, correcting my english ? _______________________________________________ Openpbx-users mailing list [email protected] http://lists.openpbx.org/mailman/listinfo/openpbx-users
