asterisk users - Jun 2009 - Problem with DTMF detection in ast_app_getdata (*1.2)

Hi,

I am using a basic VOIP phone (find here:
http://www.tootoo.com/d-rp20207560-VoIP_phone/) on an Asterisk
1.2.26-BRIstuffed-0.3.0-PRE-1y-q version of asterisk. I am running a C-based
prepaid application based on MySQL that accepts dtmf events from the phone
to authenticate. When asterisk is configured with DTMF mode rfc 2833 or auto
(or any of the others in fact) the ast_app_getdata method sometimes just
times out and doesn't get the DTMF events from the phone (the phone also has
support for rfc 2833 or inband). However when using auto or 2833, my
software Twinkle client will ALWAYS get its DTMF events detected without
fail (so far). Has anyone come across this situation before, I have
exhausted the options between Asterisk and my SIP phone DTMF settings. BTW I
also use rlaxdtmf=yes in sip conf. Thanks

Mos
