SIP trunk capacity is measured in concurrent call channels, not total users—size it for your busiest hour with headroom, and you avoid both dropped calls and wasted spend.
Definition: A SIP channel is one concurrent call path on a trunk; trunk capacity = number of simultaneous calls you can make/receive at once.
| Users | Typical concurrent (light) | With growth |
|---|---|---|
| 10 | 2–3 | 4 |
| 50 | 6–8 | 10 |
| 200 | 20–25 | 30 |
| 500 | 45–55 | 65 |
Newrock OM-series IP-PBX shows live channel usage; pair with UMS to monitor multi-site trunks and right-size before peaks hit.
Yes—total concurrent calls (both directions) can't exceed trunk channels.
Calls busy out; most providers let you add channels quickly—monitor and adjust.
Video is separate media but still one call; bandwidth, not channels, is the constraint.
Some providers offer burst capacity; confirm terms to avoid surprise overage.
Size SIP trunks on busy-hour concurrency with headroom, not headcount. Monitor actual usage and adjust—capacity planning is ongoing, not one-time.
