I have an issue where a user will answer an extension call using the 3CX software and it will crash the Netgear GTP752 switch. The call is then stuck connected in the presence window so I believe based off of that the call thinks it completed. I am steering to a codec negotiation at the switch but not sure what codec the softphone uses. I have updated the firmware and bootcode for the switches but problem still exists. I have looked at the log but haven't been able to determine anything from it at this point so looking for some peer discussion about it.
