Hi guys, I've a strange problem.
My scenario is a linux box running asterisk, and a Cisco 800 in the same LAN. The system has been working fine, except for an old H323 driver i've compiled to asterisk. So, I've rebuilt the pwlib and openh323 libraries with a new version (a requisite for the new H323 driver), and I've compiled the H323 driver with the new source.
I didn't change my Cisco configuration. But after that, some strange thing happens: when I pick up my phone connected to Cisco, and dial my asterisk configured extension, Cisco connects fine to Asterisk, Asterisk answers and sends the welcome. But for any reason, it does not recongnize the DTMF tones I send with my phone.
CISCO probably sends DTMF inband. If this is the case then the inband DTMF detection is done inside ASTERISK (dsp.c) and not in the H.323 channel driver. I have a rather old snapshot of ASTERISK source (~2 weeks old) and inband DTMF detection works fine.
If the CISCO doesn't send DTMF inband then this is a problem of the H.323 channel driver and I 'll have to check it.
So, check to see how does you CISCO send DTMF.
Regards, Michael.
There were no problems in the compilation stage of any module. I've been debugging, but I can't find where the problem is?
Has anyone suffer the same?
Regards, Carlos.
