Call Forward all - disappears after a few minute

[ErebusOZ]

Hi Guys,

Stuck on an issue related to "Call Forward all" when applying to a Cisco 7941 or 7961 series IP Phone.

User enters his/her forwarded number and all works fine, untill anywhere between 10min - 45minutes later, for some reason or another the forward all icon on the 7941 disappears and "call forward all" is not active no more - gone, not to be seen grrr.

I have tested with my phone also as a few other phones of the same type, and still same result. Call Forward All disappears after a small time.

Testing has been done with an external number (Mobile Phone number) with internal or external calls coming through to forwarded number.

CUCM 6.1

Thanks in advance.

Peter,

what exact version of 6.1?
Can you forward it again after it unforwards or is it denied?
Are you using "time of day routing"?
If you are sure this is not a user error then it must be a bug (although never heard of this in any version).

hi whykap,

System version: 6.1.2.1106-1
Once it goes to unforward the user is permitted to forward again with no errors and this process continues, no matter how many times you forward on.

with regards to "time of the day routing" i never heard of that before, so i cant answer that sorry.


Thanks,

That version had a lot of bugs. Although I never heard of this particular issue or run into it does not mean it's not a bug.
If you have verified that this is not user error and you can duplicate it consistently then I suggest a TAC case.

These are not shared lines among multiple phones and users by any chance?

I have duplicated the incident and can confirm that all users that are having this issue dont have multiple lines or shared lines, only their primary extension. The only thing that comes to mind is OCS, which we have just recently implemented. other than that no major change has occured on our end. I was going to raise a TAC but only as a last resort.

Thanks for your help.

I looked into this problem on Cisco web site. I could not find any Tac Cases or bugs with your issue.

report back with the fix as I am interested to see what TAC came up with on this one.

im curious, when the user sets the forwarding and it can take anywhere from 10 -45 min to disapper, does the calls or type of calls that are coming into that ext while its forwared affect anything with the timeing of the failure?

Dont know if this even could have an affect, but I am wondering if something with the incoming calls to the forwarded ext could be affecting the break.

If you create a new ext that no one knows to dial and forward it, does it fail since no one is trying to reach it?

Again, I am just curious.
Good luck....

Looks like i was sorta right, a battle between Cisco and Microsoft. I just got off the phone with our partner professional services and was told there is an issue with communicator's LCS and cucm.
The service guy asked me to run a test to show me what would cause the cancellation of the forward all.

- sign out of Communicator
- Call forward to my mobile number on the ip phone
- sign back into communicator
Bang! forward all disappeared grrr

He said that a colleage had witness this issue before and wasnt sure if a solution has been found and will contact me later.

Hopefully i can post a solution if he returns back with one, otherwise will need to inform the end users to uninstall Communicator if they want forward all..grrr

Looks like my only hope is to remove the link between cucm and lcs with a reg hack from Microsoft..
Basically the reg hack removes Communicator from controlling the call forwarding settings.
