VG224 DTMF CUCM 6.1(2)

Unanswered Question


last week I upgraded a CUCM server from 5.1(3) to 6.1(2).

Now I do have some issues with VG224 (doorbells).

The VG224 are connected via MGCP.

IPhone - VG224 - AnalogPhone (doorbell)

Send “0#” ---->>>

If I am connected to the doorbell - I should be able to open the door by dialing “0#”. (It worked on CUCM5)

But now I have to dial it twice to open the door. (nearly every time)

I also tried SCCP but it is the same problem.

It is the same if I use a mobile phone. So it has nothing to do with the phone firmware.

Mobile phone (PSTN) - GW(CUCM) - VG224 - AnalogPhone (doorbell)

Send “0#” ---->>>

I am using an “vg224-i6s-mz.124-11.T1.bin” image.
