I've done some more experimenting tonight.

I've noticed that in about 1 in every 4-5 calls Sipbroker negotiates a G.729 call with my Asterisk box. At this point the DTMF signaling works fine.

Every other call is uLaw and DTMF fails with this every time.

I have tried every possible setting for DTMF.

dtmfmode = rfc2833 ; The default setting
dtmfmode = inband
dtmfmode = info
dtmfmode = auto
relaxdtmf = yes

None of these made any difference.

I can only conclude that it's a problem at the SipBroker end?

Can someone give me some idea of whats going on? Or if it is a problem with Sipbroker so I can stop trying to fix it my end and just wait?

Any help appreciated.
