Cisco Unity Connection - Miu SIP Integration, All lines are busy

[at]

Hi,

We have a CUCM/CUC Cluster since 2009 and we never had problems with accessing Voicemail. We configured a Secure Siptrunk between the CUCM Cluster and the CUC-Server.

CUCM 8.5.1SU4/CUC8.5.1SU1

2 weeks ago we upgraded CUC from 8.5.1SU1 to 8.5.1SU5

Since this upgrade we had at 2 times no voicemail access from the IP-Phones registered on CUCM-Cluster (reorder tone) - in the log of CUC we saw that  all 144 ports become busy !!

History:

Update CUC from 8.5.1SU1 to 8.5.1SU5 on Saturday 10/26

- first outage on wed. 10/31 ; 1:48 pm

- second outage on tue 11/6  10:26 am

After restart of the  CUC-Server  the system works normally - I think stopping and starting Connection Manager coiuld also be a workaround, but i did not verified this :

here the log from wed 10/31

Question:

do we have a  bug in the software CUC 8.5.1SU5 or is there another problem ?

Any Ideas ?

Hi Alex,

First of all check the capability matrix of CUCM and Unity Connection. If everything is okay

Try to recreate the sip integration with CUCM and Unity.

http://www.cisco.com/en/US/docs/voice_ip_comm/connection/2x/integration/cucm_sip/guide/cucintcucmsip060.html

In the case of the problem continue, open a tac case.

best regards,

Daniel

Hi,

we opened a tac case and it seems we run into a bug which is known in Version 8.6. (We run 8.5.1SU5)

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCuc22800

Cisco already have the fix available for version 8.6.2 ES52.

Cause we can not upgrade to 8.6 (Server Hardware not supported) we will wait for the Version 8.5 Fix.

Meanwhile I will change the SIP-Trunk between the Unity Connection Server and the Call Manager Server from TLS to non-TLS (described in CSCuc22800 as a workaround)

regards
