[cisco-voip] VG224 DTMF CUCM 6.1(2)

[ben]

Hi,

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.
