Step9: Destination Port Determination Method:
Routing mechanism in VGFX involves two things: Destination Number
Determination Method and Destination Port Determination Method. VGFX
supports following method for Destination Port Determination Method:
1. Fixed
In this method, call is routed using 'Routing Groups' programmed for the
respective port. This method is applicable for all port types.
2. Destination Number Based
In this method, calls originated on the source port are routed through a port
group based on the destination number dialed by the caller. To use this
method, program 'Port Routing: Destination Number Based' table. This
method is applicable for all port types.
3. Calling Number Based
In this method, calls received on the source port are routed through a port
group based on the calling party's number. To use this method, program
'Port Routing: Calling Number Based' table. This method is applicable for
FXO Ports, Mobile Ports and SIP Trunks.
