The basics

Wholesale VoIP termination, explained.

01

One trunk, every route

You point your SIP trunk at Twiching and send outbound calls. Each call reaches the destination network through direct carrier agreements, with premium fallback routes for tail-end destinations.

02

Quality you can see

Routes are scored live on ASR, ACD, NER and PDD. If one degrades, traffic fails over in under two seconds, and threshold alerts warn you before it reaches your SLA floor.

03

Billing that adds up

Calls are billed in 6-second increments, with a CDR for every call and a per-destination cost breakdown. There are no minimums to get started.

04

Numbers as well

Need DIDs too? Origination covers local, toll-free and mobile numbers in 191 countries, with port-in available.

FAQ

Wholesale VoIP, answered.

Wholesale VoIP termination is carrier-grade delivery of your outbound calls to phone networks worldwide over SIP. You send calls to one trunk, and the provider routes each one to the destination network through its carrier peers.

All 191 countries in Twiching's directory, on a single rate deck. High-volume routes use direct carrier agreements, and tail-end destinations use premium fallback routes.

In 6-second increments, with no minimums to get started. Each destination has its own rate, and you get a per-destination cost breakdown plus a real-time CDR stream through the API or a dashboard export.

ASR, ACD, NER and PDD, per destination and per carrier, on live dashboards. You can set threshold alerts, so you hear about a degrading route before it reaches your SLA floor.

Yes. All US outbound traffic is signed with full A-level attestation, and international CLI validation is applied where it is available.

SIP or physical interconnect provisioning takes under an hour at any of our points of presence, and partner accounts are set up within 24 hours of a signed agreement.

Yes. Your logo, your domain (CNAME), your colour scheme, and your brand name appear everywhere customers see the product. Twiching is not mentioned.
