Straight answers

Business VoIP FAQ

Start with the basics, then let us review your current bill and call flow.

What is SIP trunking?

SIP trunking connects an existing compatible phone system to the public telephone network over a secure internet connection. It can replace traditional copper or PRI lines while preserving familiar calling features.

How much does a VoIP system cost for a small office?

Pricing depends on the number of users, desk phones, call flows, internet readiness, and support level. Tech-1 Comm starts with a free phone bill review, then provides a clear proposal sized to your office.

Can I keep my current phone number?

In most cases, yes. We verify portability, coordinate the port, and plan the cutover so your existing business numbers move with minimal disruption.

Is VoIP reliable for medical offices?

Yes, when it is designed around reliable internet, network quality, power protection, failover, and sensible call-routing. Our medical office VoIP installations account for these dependencies from the start.
