[Asterisk-Users] DTMF detection when outgoing call to mobile phones
Hi all, I am trying to detect DTMF keys from a mobile when asterisk make an outgoing call to the mobile. The DTMF detection on incoming calls (also FROM mobiles) is working very well. The only problem is if asterisk called the phone... Nothing is detected. I am using a digium te205p with PMX/PSTN connection. Everything that I can find in forums are problems with dtmf detection on SIP. Any suggestions? Cheers Marc

[Asterisk-Users] DTMF detection when outgoing call to mobile phones
>From my recent problem on this sort of thing, I'd suggest you set thetimeout to around 1500ms in the feature.conf file. This is of course if your using the DTMF digit's to activate any of the features. also make the devices both sides of the call are using the same DTMF mode.

It is possible they are not produced. I'm not sure if that is a handset or network issue, but I had this happen a few years ago when implementing an IVR that called subscribers for notification, and expected input from them. Most of the time it worked, but some phones in some locations sent nothing. If the phone made a call from the same location there was no problem. Steve
