Common questions.
What is VoIP?
Voice over Internet Protocol: phone calls that travel over your internet connection instead of a traditional phone line. You only need broadband and a SIP phone or softphone app.
Do I need special equipment?
No. Any standard SIP desk phone (Polycom, Yealink, Grandstream, Cisco, Obihai) or a softphone app works. Business plans also include a web softphone in the browser.
Can I keep my current phone number?
Yes. Numbers can be ported from your current carrier, which typically takes 7 to 14 business days.
How does E911 work?
Each number is registered to a physical address. If someone dials 911 from your line, emergency services receive that address so help goes to the right place.
Is there a contract or free trial?
There are no contracts and you can cancel anytime from the dashboard; service stays active until the end of the billing period. There is no free trial.
Can I call internationally?
The service is currently available in the United States only. Numbers, E911 registration, and calling are US-based.
Is there a mobile app?
A native app is coming soon. Until then, use any SIP softphone app on your phone or the web softphone in a mobile browser.
What support is available?
24/7 AI-powered chat support built into the dashboard, with hand-off to a human agent when one is available.
