Hi, the default outbound call setup for CS 410 are hunting the free fxo port. what if i want to hunt only the 2 fxo ports. what will be my dial plan. P.s. I do know how to configure an outbound call route to only one specific fxo port. but what if fxo port 1 is busy and i want the system to automatically hit fxo port 2 but not including fxo3 and fxo4. Thanks in advance
