SIP trunk
SIP trunking in Chile
A SIP trunk is the link that connects your phone system (3CX, Asterisk, Yeastar, Vodia and others) to the public telephone network over the internet. With T-VOIP you keep the PBX you already have and improve voice quality and cost, with a single partner answering for the route.

Who is a SIP trunk for?
For companies and contact centers that already have a PBX —their own or a third party's— and don't want to change it, but need reliable voice lines, number portability or high simultaneous call volumes. If you have no PBX or want to stop maintaining one, consider the miPBX cloud PBX.
What does it solve versus traditional lines?
- Scales by concurrency: you pay for the simultaneous calls you need, not for physical lines.
- Portability: keep your numbers.
- Correct prefixes per campaign (600 and 809) so people answer.
- Traceable traffic, within regulation.
How do you ensure voice quality?
We validate routes and quality with your real traffic before you sign, and we measure how the service behaves. We operate with a 24/7 NOC and failover on the voice route.

Frequently asked questions
Which PBXs does it work with?
Standard SIP systems such as 3CX, Asterisk, Yeastar or Vodia, among others. We confirm it during the assessment.
Can I port my numbers to T-VOIP?
Yes. Number portability moves your numbers without changing them.
How do I size the concurrency?
Based on your operation's peak of simultaneous calls; we estimate it together from your traffic.
Do you run a technical test?
Yes, with your real traffic, scoped and measured, before any commitment.
Want to test our routes with your traffic?
We propose a scoped, measured technical test before you sign anything.
