Why VOIPNOX
Built by engineers who answer the phone
Plenty of providers will sell you minutes. Fewer will log into your PBX at 7pm to work out why one carrier is mangling DTMF. That difference is the whole point of VOIPNOX.
Pay As You Go, genuinely
Top up, send traffic, stop whenever you like. No monthly minimum, no termination fee, no twelve-month tie-in buried in the terms.
Quality-first routing
We buy Tier-1 UK capacity and route for connection rates and audio clarity, so your calls sound like calls — not like a bad conference line.
Security baked in
Firewall rules, ACLs and spend limits are part of the build, not an upsell. Your platform is hardened against fraud from day one.
One team, whole stack
Routes, numbers, PBX, IVR, firewall and website. One supplier who understands how all of it fits together and owns the outcome.
How it works
Live on UK routes in four steps
- 01
Tell us your setup
Share your PBX, expected volumes and destinations. A quick call is usually enough to scope it.
- 02
Account & trunk
We provision your account, issue trunk credentials or authorise your IP, and allocate any DIDs you need.
- 03
Top up & test
Add credit, place test calls with our engineers on the line, and confirm audio, CLI and routing behave.
- 04
Scale as you go
Send live traffic. Increase channels, add numbers or expand the platform whenever you're ready.
Pricing
Simple plans, quoted to your traffic
Rates depend on destination mix and volume, so we quote properly rather than publish a number that won't match your bill.

Notes from the engineers who build it
Plain guides to the decisions that come up when you move a phone system — what to ask, what to measure, and what quietly costs you money.
999 calls over VoIP: the part of the switch-off nobody plans for
Emergency calls behave differently on VoIP than on a copper line. What changes, why the address on your account matters, and what to check before you move off ISDN.

Failover: making sure a broadband outage does not take your phones with it
The objection to VoIP is that it dies with the internet connection. It only does if nobody configured what happens next. The four layers of failover, and where to start.
