Frequently asked questions
Find answers to the questions we get asked most often about SIP trunks and business phone lines.
A SIP trunk is a virtual phone line that runs over the internet instead of the traditional phone network. It connects to your phone system and enables VoIP calling at a lower cost.
Not always. We can use a gateway to connect SIP trunks to many legacy PBX systems. However, upgrading to a modern IP PBX will give you access to more features and better long-term support.
That depends on how many simultaneous calls your team handles. We’ll help you calculate the right number of channels to ensure smooth call handling without overpaying.
Most likely. In the majority of cases, we can port your existing business numbers over to your new SIP service with no interruption.
Yes—in fact, it will often be better! SIP trunks rely on your internet connection, and we work with high-quality carriers to ensure reliable, crystal-clear audio.
If your internet connection goes down, we can configure automatic call forwarding to cell phones or alternate locations to keep you reachable.
