FAQ

What is a SIP trunk?

A SIP trunk is like a virtual telephone line that you can connect your SIP-compatibe phone system to in order for it to make and receive calls. Similar to traditional ISDN channels - the number of SIP trunks you have determine the total simultaneous calls on your system

Can I use the SIP trunk outside of the UK
Yes, our SIP trunks are very good options to add low-cost call routing for non-UK based companies on their VOIP system.
What’s the contract term?

Unlimited Trunks are subject to a 1 year contract, other SIP trunks are 30 day rolling terms. A valid automatic payment method is required to cover call costs (credit card or DD or invoice subject to approval)
 

Do your SIP trunks work with 3cx, Asterix etc?

Yes, our SIP trunks work with all PBX and phone systems. We also offer expert 3cx hosted systems, handset and advice.
