I have a strange problem I am seeing in the asterisk console. I pick up a phone and make a call, I get the message attempting bridge of .... (zaptel devices) then immediately I see another message saying 3 way call and indicating the line device and then starting music on hold. (meantime the call is already connected.) I hang up from my call and then I get ringback and pickup to another instance of the line that was on hold. Anyone know what is going on here ?
