Voice & number questions
Which countries can I get phone numbers in?
Local and toll-free numbers in the United States, Canada, the United Kingdom and Australia, and local numbers in Singapore. Virtual and toll-free numbers in India are available on request through Sales.
Can I keep my existing numbers?
Yes, where the regulator allows number porting. We handle the port request with your current provider.
How are calls billed?
Per second after the first 6 seconds, at the rate for the destination country. Number leases are billed monthly. Rates are on the pricing page.
Can I connect my existing PBX or contact center?
Yes, over SIP trunking. Channels scale with your traffic and there are no per-trunk fees.
Will my US calls be marked as spam?
Eligible US calls are signed with STIR/SHAKEN attestation, which tells carriers the caller ID is genuine and reduces the chance of spam labels. Registering your numbers and following calling rules matters too.
Can I record calls?
Yes. Recording is available on every number. Some countries and US states require every party's consent, so play a recording notice where the law requires it.
