[miguel.romero]

Hi,

I have a 3cx version 16.0.622 Enterprise Edition.

I have a Call Queue created and 3 agents, all calls enter into the call queue from external.

Sometimes, the call which is forward from call queue to a Agent 1 is transfer to another agent.

The logs showing the following:

The call while Agent 1 (ext 8003) is talking with the customer is transfered automatically to Agent 2 (ext 8007).
I see a 408, Poll Expired.

What could be the cause of this?

Thanks in advanced.

Regards.

Too, when the agent 1 is talking and enter into the system other call, this call enter to this agent 1, and the call which was talking agent 1 is forward to agent 2, mixing conversation.

The scenario is: 3CX VoIP Cloud<---> SBC<--> IP Phones
