For those trying to diagnose iax2 dtmf problems associated with LiveVoip,
here is the results from "iax2 debug" after I placed a call to my account.
The ivr answered the incoming call, and I pressed "3000".

This represents a working CVS-HEAD-03/31/05 with no dtmf problems.

    -- Executing Dial("IAX2/livevoip at 217.160.244.186:4569-5", "SIP/3000|15") in
new stack
    -- Called 3000
    -- SIP/3000-ee8f is ringing

As you can see, the "Type: DTMF and Subclass: 3" represents me dialing
the digit "3" followed by 000 in the next frames. No problems whatsoever
and x3000 rang as expected.
