I have a server with Dialogic E1 , my app worked fine until i had to change the location of server and change E1 line.
Now whenever my app wants to change Voice to Fax by using of "SetCallType" method, line will be disconnected,
SetCallType result:DivaResultDisconnected ,DisconnectReason = DivaDiscReasonNormalClearing
should i change card configuration ?!
I have found the problem.
I removed my fax license then added again , this change solved my problem.
