[Asterisk-Users] DTMF tones not recognized...

[Carlos Crembil]

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.

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.

PWLib was v1.3.1, now is v1.4.11.
Openh323 was v1.9.1, now is v1.11.7.
H323 Support for Asterisk was v0.2, now is v0.5.1.
Asterisk version is CVS-03/08/03-15:48
