[cisco-voip] In-band DTMF with Cisco Call Manager

[Walenta, Phil]

What sort of gateway is it?

The problem is actually between my PSTN gateway and the CCM (I'm guessing).
The CCM is doing dtmf-relay which my gateway does not support.  The weird
thing about all of this is that when we first set everything up, we were
seeing inband DTMF from the phone/CCM and everything worked great.  A few days
later it magically changed to H245 and no one knows why or how to switch it
back.
