SIP trunking for K-12 private schools
Give families an easy way to reach the front office, admissions and every campus, on a budget your business office can plan around.

What is SIP trunking?
SIP trunking replaces traditional phone lines with voice service delivered over your internet connection. Your existing PBX connects to Resonance Telcom using SIP, the standard protocol for internet calling, and we connect your calls to the public phone network.
Instead of paying for a fixed bundle of copper lines, you pay for the number of simultaneous calls you actually need, and you can change that number from a portal in minutes.
The benefits of SIP trunking for private schools
Predictable budget
A flat monthly rate per channel and per number makes phone costs easy to plan from one school year to the next.
Numbers for every office
Give admissions, the front office, athletics and the business office their own numbers so families reach the right desk.
Campuses on one account
Lower, middle and upper school campuses can share one account, with trunks and numbers for each building.
Room for busy days
Add channels for the first week of school, enrollment season or a snow day, and scale back afterward.
Easy for small IT teams
Clear setup guides and a simple portal mean one technology coordinator can run the whole system.
Why schools choose Resonance Telcom
- Small IT teams get clear guides and engineers on call instead of a complicated carrier relationship.
- Per-channel pricing keeps the phone budget predictable year over year.
- Multiple campuses run on one account with central management.
FAQs
Can each campus have its own numbers?
Yes. Order numbers for each campus and office and route them to the right extensions or ring groups.
What happens during enrollment rushes?
Add channels in the portal before your busiest weeks so families do not hit a busy signal, then reduce them when calls slow down.
Is setup hard for a small IT team?
No. Setup is a short checklist of settings in your PBX, and our team can walk you through it.
