What is a SIP trunk?

Already have a phone system at the office? Then we connect it to our network over the internet. You keep your own equipment, but from now on you call over the internet instead of old-fashioned phone lines. That is usually a lot cheaper.

Already have a PBX at the office? Then we connect it to our network over the internet — that's called a SIP trunk. You keep your own equipment, but from now on you call over the internet. That's usually a lot cheaper than fixed phone lines, and you can easily handle more or fewer calls at once. We set up the connection for you.
