1.1 Basic System Construction
1.1.6 Recommendations for System Configuration
In order for the VPS to handle calls smoothly, generally there should be 1 VPS port for every 6 trunks
connected to the PBX. If Automated Attendant (AA) service is used, allotting 1 VPS port for every 4
trunks should be sufficient. If the PBX and VPS have heavy traffic and callers cannot reach the VPS
because of congestion, more VPS ports should be added.
Recommendations are outlined in the following charts.
