Call fails in a scenario

Unanswered Question
Dec 15th, 2009

Hi All,

I have been facing an issue in a specific call scenario involving 7960 phones. The call scenario being as follows:

1)      Phone A, B and C are in same CSS.

2)      Phone A and B in same partition, while Phone C is in Null partition.

3)      Calls to Phone C from Phone A and B happens, but vice versa fails.

     This happens only when Phone C is 7960, otherwise it works well.

Let me know how this can be resolved. The UCM being used is 4.3(2)ES 21 and the phone load on phone 7960 is P00308010200

Thanks,

Nihar

I have this problem too.

Then most probably you would need to look at a CUCM trace to determine the root cause, if it's CUCM routing gone bad or if it's really something on the phone.

Phones are basically dumb, they work on stimulus-response way so CUCM is the one that takes care of routing, i don't believe this is related to the phone model. It's probably a phone config issue.
