Questions
Feature FAQs
Do I need to buy new hardware?
No. NumbersOne works on our free desktop and mobile apps, and with any standards-compliant SIP handset. If you already own IP phones, our SIP trunking option lets you keep them.
Can I keep my existing phone numbers?
Yes. Porting is free and typically completes in five to ten working days depending on your current carrier and country. Your service stays live until the moment the port completes.
How many extensions can I create?
Starter includes five, Business includes twenty, and Enterprise is unlimited. Extensions can be added to any plan mid-cycle and are billed pro-rata.
Is call recording included?
On-demand recording is available on all plans. Always-on recording with extended retention is part of Business and Enterprise.
Which systems do you integrate with?
We provide native connectors for major CRM and helpdesk platforms, plus a documented REST API and webhooks so your developers can build anything else you need.
