CUCM 7.1.5 Random auto dial last missed call problem

Unanswered Question

We are running CUCM ver with 7940,7941,7961 and 7962's deployed at mutliple locations.  There have been at least 5 different phones at different locations that will auto dial the last missed call as soon as the handset is picked up.  The users are not setting this option and I can't seem to find anything in CM that sets this as a user configurable option.  The fix so far has been to reset the phone.  Anyone have any ideas as to what would cause this?

Hi Troy,

Just to clarify here, are you saying that the user is not looking at the

Missed Calls screen when this happens? If so, is this happening on

a particular IP Phone model? It doesn't seem to be a CUCM bug as far as my

search has led.

If they are looking at the Missed Calls display then this is working as designed

Hi Rob,

The user is just picking up the handset to dial a number.  They are not looking at the missed call list.  It has happened on a 7941, 7961 and a 7962.  It has happened to phones that are setup with a device profile and phones that are not using a device profile.

Hey Troy,

Well that's an odd one for sure

I've looked for Bugs @ CUCM 7.1 and IP Phone Firmware 8.5 and 9.0

which I'm guessing these phones are running......and I can't find anything

my friend. Maybe someone else has seen this. Or perhaps it's time to

open a TAC case.

I also checked the CUCM 7.1(5) release notes just in case this was some

crazy new "Feature"

Cheers! Sorry about that

Hi Troy,

We are also facing the same issue in one of our customer place. Could you please let me know if TAC has provided any solution for the Random Dialing from the missed call. We also opened a Case with TAC but till date no resolution provided.

We opened a TAC for this, and Cisco got a  fix for new defect CSCtz29414 will be made available in the 9.3.1 firmware release, scheduled for June.

Affected Phones for us
