SIP Trunk
What is a SIP Trunk?
Already have a PBX at the office? Then we connect it to our network over the internet — that's a SIP trunk. From then on you call over the internet instead of old-fashioned phone lines. That's usually a lot cheaper, and you keep your own equipment. Ideal if you only want to outsource the calling connection. We take care of the setup.
- We set up the connection for you, personally
- Choose pay-per-minute or unlimited calling
- Number porting available
- Cancel monthly
- Extra call channels easy to add

What makes our SIP Trunk different?
Easy to connect, reliable in use and flexible to manage.
Stable connection
Redundant servers and encrypted connections give you a reliable line that just keeps working. Compatible with all major PBXs, such as Asterisk, FreePBX and 3CX.
Scale whenever you want
Need more simultaneous calls? Adding or removing a line takes no time. No long-term contracts and no setup fees.
Pay per minute or a flat rate
Don't call much? Go with the Basic plan. Call a lot? With the Unlimited plan you always know what it costs.
Bring your number with you
You simply keep your existing landline numbers. We handle the entire porting process for you — nothing for you to do.
