CUPC users issue, could not make call

[bijaigurungNSC]

Hi,

Few of the users experienced outage for about 20 mins, users were still logged in but couldn't make calls. No issue on call manager services seen at that period.

Could you please advise how to go about troubleshooting, which service logs from RTMT should I be chasing after to narrow down the issue ?

Thanks in advance.
 

CUPC ver: 8.6.1
Client services Framework : 8.5.(6)

Platform Version 4.0.0.0-36

You will have to pull CallManager traces for that time period. Traces will only be useful if logging is turned up to detailed.
