I been having issues when I can an extenal number that has IVR. The key I
press are not recognised sometime or are miss read. My Asterisk sever is
connected to PSTN through a SIP trunk to a provider so am not connected to the
PSTN network Directly...
I have no issue with DTMF when I acces Voicemail or any IVR prompt on my
asterisk server, the issue is just when I call an external number... Currently
all my SIP clients are set to DTMF=RFC2833 in sip conf and on the Devices too...
Codec i'm mainly using is ulaw and the Asterisk version am using is Asterisk
1.2.13 svn rev 47264...
I'm wondering if someone has come across the same issue or has a workaround..
Thanks
mohamed.
