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 (CO
lines) connected to the PBX. If Automated Attendant (AA) service is used, allotting 1 VPS port for every 4
trunks (CO lines) 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.
