Hi,

No timers. Are you using g.729 ? H.323 or SIP ?

You need to configure an option for "dtmf-relay" under "dial-peer", depending on the above.

Hope this helps,please rate post if it does!

hi,

the point is.. that call didnt even reached the voip (ip) side (dial-peer voip). I'm getting duplicated/messed up DTMF entries to indentify the customer PIN at the pots leg.

This service use H323 and we use g729, g723 and g711

thanks

Do you use a TCL/IVR script for PIN authentication? If so, which one? How did you diagnosed DTMF problems ?
