Unity Connection with PIMG Bug info

[Rob Huffman]

Hello all,

We are running Unity Connection 7.1(3b)su2 - 7.1.3.32900-4 with a couple of PIMG

units running 6.0.SU3.2.002. We get the PIMG's completely locking up at random times.

Sometimes it's a week or two between lockup's. I'm trying to confirm if the Bug fix for this issue

is included in our CUC build? The fixed in versions do not show 7.1.3.32900-4 and I can't seem

to secure this info from the ReadMe's or release notes (maybe I'm blind ).

UC with PIMG fails Keep Alive and erroneously places port out of service

Symptom: Cisco Unity fails 60 second keep alive and regardless of what happens within the next 30 second ack we put that port out of service. Conditions: Cisco Unity sends a Keep Alive to each PIMG device every 60 seconds and it expects the PIMG device to respond with an ACK within 30 seconds. If an ACK is not received within 30 seconds, Cisco Unity connection will reduce the Keep Alive interval to 30 seconds so we are able to detect a potential outage quicker. Even though Cisco Unity Connection may receive an ACK within 30 seconds it still places that port out of service. Workaround: None Further Problem Description: What we expect to happen in this scenario: Cisco Unity sends a Keep Alive to each PIMG device every 60 seconds and it expects the PIMG device to respond with an ACK within 30 seconds. If an ACK is not received within 30 seconds, Cisco Unity connection will reduce the Keep Alive interval to 30 seconds so we are able to detect a potential outage quicker. Should Cisco Unity Connection fail to receive an ACK after two tries that port is placed out of service.

Hi Curtis,

Thanks so much for linking this up for me I don't

think I ever thought to look in the CUCM Readme. I have a TAC

case open and am working with Tim to resolve this issue.

Cheers! And Thanks again!
