i use mpe create a meeting, and invote another man to join it though mpe out-dial.
the man can listen the voice menu, prompt him press "1" to join the meeting, but mpe can't detect the dtmf.
and i turn debug on voice gateway: "debug voice ccapi inout". find that the voice gateway can't detect dtmf signal too.
but i from outside dial out ipt system, ipt system can detect the dtmf signal (like out IVR system).
who can tell me what problems occured?
