I am having a hard phone and a CUPC.If i answer the incoming call in ip phone,then CUPC shows this call as a missed call,but actually i answered the call.This happens when i select the softphone in CUPC.Please suggest a solution to resolve this strange behaviour.
I apologize, I missed the intent of your post. This behavior is not "strange", it is deliberate. Any time a shared directory number is called, every device that does not answer that call will log it as missed, including Cisco phones, CUPC, CIPC, and all remote destinations.
I know that's not what you wanted to hear but I think that's just how it is....
