>From which channel do you make the call? (Zap? SIP?)  Looks like a DTMF 
detection problem.  If ZAP, you better use longer tone.  You can try 
relaxeddtmf in zapata.conf, but people generally recommend against it.  The 
card you use also matters.  Heavy echo could also interfere with DTMF.

If SIP, the symptom you described would happen only to inband DTMF.  Try not 
to use inband if you can help it.
