I have a Merlin Magix 4.0 in Key mode. When the customer transfers a call to an outside number the call completes. But the trunks stay connected they do not drop off when the caller disconnects. I have turned on Trunk to Trunk for each station and I have the loop start disconnect set to yes. the customer transfers a lot of calls outside and his trunks are getting tied up untill he goes in on the trunk and then hangs up. By the way all calls come into an auto attendant. the Merlin Messaging unit is a 6 port rel 1.5. Any ideas?
