half of inbound calls dropped.

[HafezAlzindani7306]

Guys;

We are facing high number of calls dropped on the CTI level before reaching the agents. Half of the inbound calls dropped before reaching the agents and in the first second of call.

Call flow (HA):

External Caller >> Voice gateway CUBE >> CUCM Cluster >> UCCX (Script) >> Agents.

can any one help me in this critical case?

Hi,

Login to RTMT and check CUCM for any error message including memory, cpu,
etc. Also, from RTMT try to go to session trace or real time trace and
lookup a failed call. See what is the cause code for termination. Also, you
can see this from CUBE using the debug ccsip message.

Do the same thing on UCCX to see if any issues with the VM interms of cpu
and memory.
