Is there any way to forward an incoming call to an external number without tying up 2 lines for the duration of the call? The lines are all analog and PRI Centrex lines. Their current PBX system does this using hook flash. I’ve looked up FXO hook-flash command but I’m not sure if this is what I’m looking for. Basically all calls come into a receptionist and from there they are transferred to the appropriate extensions. Sometimes transered to ohter schools accross the Centrex lines. How can we accomplish this on their CUCM 8.6 system without tying up 2 lines while the call is in progress?
