[asterisk-users] GSM Module not picking up DTMF digits from VOIP FXO Gateway

Hi,

I've connected a GSM gateway to a WellTech 3702A FXO port and created an
extension in Asterisk which mobile calls are forwarded to. When a call is
made, the GSM module generates a tone instead of picking the digits from the
Voip gateway and processing the calls. The VOip gateway keypad type is
RFC2833.

When the GSM gateway generated the tone, i can then type and the call goes
thru. Why is the GSM module not getting the digits automatically as passed
from Asterisk via WellTech 3702A gateway?
