Works with standard SIP
Any PBX, softswitch or dialler that speaks SIP can connect: on-premise systems, hosted platforms and open-source ones alike.

Keep what you have. Change the network under it.
A SIP trunk replaces phone lines with a connection over the internet. Your phones, menus and reports stay as they are; the calls run on Cloudvoice.
Numbers worldwide on the trunk
South African and international numbers (DIDs) routed to your system, so customers in each country call a local number and you answer on the equipment you already use.
Your AI platform, on real numbers
Connect a voice agent you've built, for example on ElevenLabs, to a Cloudvoice number so it answers and makes real calls.
Outbound with your caller ID
Calls out show the numbers that belong to you. Add caller identity management to see how those numbers appear on people's phones.
A record of every call
Each call is logged with its time, numbers, duration and outcome, so you can check traffic and reconcile your own reports.
Global reach
Call destinations around the world from the same trunk, and add numbers in new countries as your business grows.
Bring your own AI agent
Voice AI platforms connect to the phone network over SIP. Point your agent at a Cloudvoice trunk and it can answer a local number, call customers, and transfer to your team, while you keep full control of the agent itself.
- Inbound: callers dial a local number and your agent answers
- Outbound: your agent calls out with your caller ID
- Handover: transfer to a person on your PBX when needed

Good to know.
Do I need new phones or a new PBX?
No. A SIP trunk connects to the system you already have. If you'd rather not run a PBX at all, our Hosted PBX runs it for you.
Can I use the trunk for an AI voice agent?
Yes. Any voice AI platform that connects over SIP can use a Cloudvoice trunk and numbers. We can also run AI agents for you on our own platforms.

It depends on your trunk. Tell us how many people take calls and how many calls you run at peak, and we'll size it with you.
