1.) From what are you calling?  A phone connected to an FXS port?  A SIP 
phone?

2.) How is your * box connected to the PSTN?  A T1/E1 interface?  SIP 
connection to ___?  IAX connection to ___?  An FXO port?

3.) Are you sure that DTMF is working at all?

4.) Have you tried looking up DTMF in the wiki?

Yours,
