PBXDom Top 25 Trunks/COs with illustrative data for September 11, 2026

What to notice: Trunk 1 carries 270 of 360 incoming and outgoing calls (75%); trunk 2 carries 90. This ranks traffic volume, not simultaneous occupancy or spare capacity. Use concurrent-call data before making a capacity decision. Only two trunks exist in this example, so this top-25 report has two rows.

1. Trunk/CO: the name or the number of the landline

2. Count: the total number of incoming and outgoing calls received and made by a landline

Note: Trunk, CO, and landline are the equivalents of each other and can be used interchangeably.
