[cisco-voip] DTMF Issue with one external number

[Buchanan, James]

I have had this issue dialing into specific conference bridges. The only solution available at the time (it was 7.1 three years ago with CUBE 1.4) was to require an MTP.

Hey guys,

  We have an odd issue going on with DTMF.  Below is the path to the PSTN.

CUCM <-> h.323 Gateway <-> SIP Provider.

The problem is that when we dial into this one external number and press 1 to select option 1, it doesn’t seem to accept the digit.  If we dial into that same number from anywhere else, it works fine.  Having said that, I can dial into other numbers from the system and have no issue at all with dtmf.  Any ideas of what this issue is?

Thanks,
Bill
