Callers hear busy tone (IPCC Enterprise Solution)


I have suffered a very strange issue with an IPCC Enterprise and I'dont which is the reason:

My platform is:

  • CUCM cluster version 6.1.4 (1 Publisher and 5 subscribers) connected to PSTN using a H.323 IP Trunking solution.
  • IP IVR 5.02 (2 with 30 ports each one)
  • ICM 7.2.6

The issue is follows:

     All the platform is working fine, but suddenly when callers call the contact center, always hear busy tone. I have rebooted call all the cluster (twice), the IP IVRs without any success,  but when I rebooted Side A and Side B PGs, all starts to work fine again.

I have reviewed  logs from PIM, OPC, JGW from IPCC and the logs from IP IVR, and I only have seen on strange thing. This strange thing is that during 30 minutes, in the IP IVRs logs appear the following message:

181347915: Dec 12 21:37:23.521 CEST %MIVR-SS_TEL-7-UNK:... CTI Port recovery 'MIVR_SS_TEL_RECOVERY_0_-50-0' @ 1260650243521 done.

181347923: Dec 12 21:41:19.385 CEST %MIVR-SS_CM-7-UNK:Cleanup in ContactMgr complete

Only when I reboot CUCM cluster, appears new  traces indicating that ther are traffic at IP IVRs CTI ports.

Could anybody helps me with this issue?

Hello Antonio,

can you tell how do you solved this situation, cause I faced with same problem.

Thank you,


Re: Callers hear busy tone (IPCC Enterprise Solution)

Is it only new callers that hear busy tone?  What about current callers in the IVR?  You might be running out of ports, can you look at your CT WebView report to see how many calls you're getting?


Re: Callers hear busy tone (IPCC Enterprise Solution)


our problem was related to a performance problem that cause that all cti ports  & Route points becomes unregistered.
