Who it's for
Built for teams that live on the phone
From a five-person office on 3CX to a contact centre dialling all day, the same trunk, the same proof, sized by plan.
Call centres
100 concurrent calls on Call Centre and more on request, 10 calls per second and autodialer traffic allowed. Your caller ID reaches the handset, so customers know who is calling.
Small and growing businesses
A bundle with UK mobile minutes, concurrent calls and local numbers included, month to month with no setup fee.
PBX owners
Already run 3CX, FreePBX, Yeastar or Grandstream? Follow the guide for your system and watch each connection check pass.
Resellers and IT providers
Run your clients' phone systems on pay-as-you-go rates from one account, with every trunk, number and bill in one place.
Caller ID, proven
See the result before your customers do
We call real phones on each destination network and check what the screen shows. Only routes whose latest test showed the exact number carry business trunk calls.
A route that loses its result leaves the set on its own, and your portal keeps the latest test per country and network, with a test you can run on your own number.
- 2,885 real-handset tests in 71 countries since July 2026
- Caller ID tests included every month on every bundle
- Calls with a missing or unverified caller ID are stopped before they leave

Why PacketExchange
Carrier-grade routing, business-simple billing
Your trunk sits on a live marketplace of carrier routes. You get the routing a carrier would build, without running one.
The best tested route for every call
Each call is matched to the number you dial and routed by cost and measured quality across the marketplace, with automatic failover. Answer rates and call lengths are measured on real traffic.
Live in minutes, not days
Self-serve setup with guides for 3CX, FreePBX, Yeastar, Grandstream and Teams. A live check walks reachability, sign-in, inbound, outbound and two-way audio, and points to the step that failed.
Numbers in 36 countries
Local, national, mobile and toll-free numbers, included on every bundle and added from the Number Store in a few clicks. Keep your own by porting them in.
Search numbersBundles or pay as you go
Bundles include UK, mobile and international minutes and concurrent calls, with no channel fees, setup fees or contract. Pay as you go needs no monthly fee at all.
AI voice agents on the same trunk
Describe an agent in plain English and point it at a call list: it makes outbound calls over your trunk at $0.25 a connected minute.
AI voice agentsOne bill for all of it
Plan, numbers, minutes, recording and add-ons on one invoice, with VAT where it applies. Every call is in your records, with a SIP trace when one needs explaining.

Bundle minutes are for person-to-person business calls and reset each month. Each destination group has its own minutes, and the rate card below lists what every group covers. Minutes beyond the bundle, and destinations outside the groups, bill at the rate card. Outbound autodialer traffic is welcome on Pay as you go and Call Centre; on Starter and Business it bills at pay-as-you-go rates.
Volumes above Call Centre: custom rates from a $2,000 monthly commitment, with a dedicated IP. Talk to sales.
Not available: US and Canada, emergency calls.
Business SIP Trunks do not support emergency calls. Calls to 999, 112, 911 and other emergency numbers are refused, and we cannot pass your location to an emergency service. Keep another phone line, such as a mobile or a landline, for emergencies. Calls and numbers in the US and Canada are not offered on any plan.
