UCCX Phones Ringing Once

Unanswered Question
Jun 28th, 2010

Encountered a situation where CCX phones are ringing only once.  It is random and I have not been able to duplicate.  Anyone have anythoughts?  It is only being reported on Contact Center phones.  CM 7.1.3b , UCCX 7.0 environment.


I have this problem too.

It's possible the external caller is hanging up..

1) Get the agents to log the calling number and time of the call when it happens (getting CLI from their call log report in CAD).

2) In CCM, have detailed tracing enabled - drop the logs into triplecombo and see whether the ISDN disconnect originates from CCM, or from the PSTN.

Also make sure that your exact versions of CCX and UCM are listed as compatible. Small version changes in one product or the other that are not explicitly listed in the compatibility matrix has resulted in odd JTAPI behavior such as this in the past.

I am using:


UCCX v. 7.0(1)SR05_Build504

I have consuleted the compatability matrix


PG. 51ish shows that they are compatable.

Thanks for the suggestions.  The issue is really random thus making it pretty difficult to troubleshoot, guess I just need to sit and wait until it happens again to grab the logs.
