[Asterisk-Users] Dial Option "wW" picking up the *1 is a bit flaky

[Adam Hatia]

Both the SIP phone, and asterisk (when the call is via our IAX line) use
alaw. If the external call is via the Zap interface, it's equally
unreliable.

Where can I see what DTMF mode is being used by * and the SIP phone?

Sounds like you are using an inband codec and not using ulaw or alaw. 
If you are not using alaw or ulaw, then you need to use either INFO or 
RFC2844 DTMF.   Just remember that both Asterisk and the phone device 
MUST be using the same DTMF mode.
