It is a PSTN dialpeer here, and it cannot be defined on it...

Unfortunately this does not work on PSTN dial peers.

This indeed shows that it has negotiated rtp-nte. Even when I do debug for
CCAPI events (I think) I see it decodes the DTMFs; however, it ignores them
while it accepts them via INFO. As I said: I guess this is a bug.

Since the gateway is on a remote site I hesitate on upgrading it until I hae
the chance to go there.
