I have a Cisco 7940G phone that is SIP configured. I have noticed that after a period of inactivity (making or receiving calls) if some calls the phone won’t ring. However if I just recently used the phone (made a call) and someone calls it will ring just fine. Is there some kind of idle setting I’m missing? Is this a known issue? Might it be something to do with how my phone is connected to the network and possibly a port issue?? Thank you!
