RE: Help with DTMF problem

If your remote site phones are controlled by the CallManager when WAN is up, then you are not actually using
those H.323 dial-peers. Your call signaling is: IP Phone ---- SCCP ---- CM ---- MGCP ---- CMM ---- ISDN ---- PSTN. Unless
I'm missing something. So, this issue would be with the CMM+MGCP+ISDN. What IOS version are you running on
CMM? Ibm looking at the oldest 12.3(8)XY code and it has a lot of DTMF bugs. You are either running 12.3(8)XY-
something, 12.4-something or 12.4T something.

replicated on both and differentiated with "preference" commandB B So the devices at the site am at use them as
SRST routers when the need arise. Samples below
