I have a customer who has a Magix connected to analog ports off a Nortel (Don't know which one but its real big). The get DIDs from the Nortel which they use as the main numbers that point to the nortel ports and come into loop lines on the Magix. The Magix is in key mode and they have the 5 lines on all the phones. Everything works fine except the disconnect. The Nortel is not sending far end disconnect to the Magix so the voicemail never drops the call if the caller hangs up. The owners of the Nortel admit this and say they will do nothing about it. Does anyone have suggestions as to what I can do?
