[Asterisk-Dev] Asterisk Dev wanted for quick job

[Phil Doroff]

Unfortunately it does not appear this works.  Had my hopes up though!  Put
the dtmfmode command in both the general and phone-specific areas of
sip.conf to no effect unfortunately.

I did make a typo in the original post, OUTofband needs to be hacked up to
fix the cisco bug, not inband.  Ask alex how I confuse the two constantly.
:)

I will get packet logs shortly, have to figure out how to turn on that level
of debugging again.

thanks much for all the responses,

-Phil
