I've got an issue that's a little perplexing. We have a DID assigned to call group. Two phones are in the call group. One is a Cisco 508G and the other is a Panasonic cordless phone. If the call is answered on the cisco phone, the phone can't' hear the caller's voice. If the call is answered on the cordless phone, everything works as it should. If I call the cisco phone internally, the phone works just fine. If the Cisco phone makes a call, everything works as it should.The issue only seems to happen on inbound calls and only on this one phone. Any other calls to any other DIDs, Call Groups, etc all work fine across the system. Things I've done to try and remedy the issue: 1) Reset the phone and reprovision 2) Swap out the phone with another 508G 3) Change ports on the switch Any suggestions?
