Hi victorwoon,

Thank you for your time, and to respond to your question, I'm using a SIP route. They same trunk installed on the system (A2B) and using for normal SIP calling (working fine) but when you try to call the DID dedicated for the callback, it calling back, and ask you to enter the phone number you wish to call, and after you entered the number and press the #, the call just hanged up. Please help.

Regards,

Try one of these in your trunk settings:

dtmfmode=rfc2833

or

dtmfmode=inband

Cheers
