[cisco-voip] CUCMBE 1/2 ring dropping calls

[Lewis, Chris]

Thanks all for the input.

Seems that the issue is one of the IP Phones going Off Hook/On Hook intermittently and only at the exact time that someone calls and it does its thing does the fault occur.

Replacing the Phone looks to be the answer. It’s a 7962 with 9-0-3 (SCCP) BTW

Doh this is BE so not clustered just standalone.

Sorry for any confusion

Also, this happens on IP to IP calls intra cluster as well

I’ve seen this behavior with POTS line for which caller ID is enabled on the FXO port. I’ve had to put a ring timer in there before.

All,

Anyone ever see an issue with incoming calls dropping after users hear ringing for approx ½ second?

Traces show the call being picked up and disconnected correctly.

All the numbers are shared lines and I am damned if I can see any issues with DN’s or the phones.  Have similar configs on other phones on CUCM 8 and CUCM 6 clusters with no issues.

TAC see the same as me for traces also so thought I would ask on here to see if anyone has experienced anything like this.

Any and all ideas welcome

Chris
