Does InfiVoice work with Twilio and Plivo?
Yes. The InfiVoice integrations page lists both Twilio and Plivo under telephony, and it also lists SIP trunking for your own lines. Free includes 100 credits to test it.
What the site says about each provider
Twilio is described as a global telephony provider for voice calls, SMS and phone number management. Plivo is described as an alternative telephony provider with strong coverage in India and international markets. Both appear in the Telephony group of the integrations page, https://infivoice.com/integrations (checked 13 Nov 2026).
Your own lines and PBX
If you run your own phone lines, SIP gateways or a private PBX, the integrations page lists SIP trunking as a separate option. It is active on the Pro plan only, with up to 25 concurrent SIP calls. The details are in our SIP trunking answer.
Numbers inside the platform
You can also buy a number from within InfiVoice on both Free and Pro, so a provider account is not the only way to get a line. See buying a number inside InfiVoice.
What the site does not say
The site does not publish a setup guide for connecting your own Twilio or Plivo account, which plan the provider options need, or whether the provider bills you separately. Ask support before you plan a migration around it. If you only want to keep your current public number, our guide on whether you need to change your number covers the options.
What it costs
Free has 100 credits. Pro is $79 per month with 250 credits. One credit equals 60 seconds. You can see how credits work and compare plans on the pricing page.
