Callee Phone is not ringing


#1

Hi All,

We are facing issue that Callee end phone instrument doesn’t ring on Incoming Calls. Below is the scenario that will clear the situation:

PORT1 user Dials to PORT2 user using Inter Port Calling by dialing ***702.
PORT1 user instantly gets ring for the call but PORT2 user instrument doesn’t ring.
If PORT2 user picks the receiver same call will connect and Audio will flow properly.

So here issue is only with the Ringing of the phone and its happening with many ports of device. Some ports on the same Device are working fine without any issue.

We have tried with rebooting the device, changing phone instrument and cable but situation remains same. Kindly help if any other troubleshooting needs to be done to resolve this.
