[Asterisk-Users] no DTMF pass-thru

[Asterisk]

Hi all,

We have a little problem.
One of our customers has a problem with DTMF pass-thru.
They use GrandStream 286 devices to connect their pstn phones to
asterisk.
everything works like a charm, except DTMF pass-thru. when they call
an IVR system, they cannot select options because the DTMF tones
never reach the IVR.
Normal asterisk voicemail works though. so it looks like asterisk is
not forwarding the DTMF tones to the zap interface.
Is this a setup problem or asterisk intended?

Regards.
Andre
