I'm new to programming the merlin system (legend/MLX). It is a R2 system with 40 DID lines through 800 DID module, using (3) 408 GS/LS-MLX modules and a 012 basic telephone module. Right now all my DID are assigned to extensions in the system (ext# 400-439), NOT ALL EXTENSIONS ARE IN USE. I would like to use ext# 420 to be used to connect to a fax machine. Currently ext# 420 is connected to port 20 on a 408 GS/LS-MLX module. I would like to connect a fax machine to port#39 (ext 7138) on the 012 module board. I have tested outgoing faxing and can dial out using 9, access to send. How can I redirect the incoming DID line xxx-7420 (ext 420) to the fax machine?
