[Asterisk-Users] X100P not passing DTMF through?

[Andrew Kohlsmith]

I have a simple little asterisk setup:  FXS is a PhoneJack PCI, FXO is an 
X100P.

I have a regular old cordless phone plugged into the FXS port.
I can dial anything and it's picked up properly by *.
I can call FWD and it picks up the DTMF properly.
I call out the FXO but nothing I call through there can hear the DTMF 
clearly.  Bell Canada's Call Answer service, for instance, can't pick up my 
passcode.

Any ideas?

Regards,
Andrew
