Does InfiVoice support SIP trunking?
Yes. InfiVoice lists SIP trunking for connecting your own telephony lines, SIP gateways and private PBX networks. It is included in the Pro plan at $79 per month, and the Free plan does not have it.
What SIP trunking does here
The integrations page describes SIP trunking as a way to connect custom telephony lines, SIP gateways and private PBX networks to the platform. If your business already runs its own phone system, this is the route that lets calls reach an InfiVoice agent without moving everything to new numbers.
Which plan includes it
Pro has SIP enabled, with up to 25 concurrent SIP calls. Free has SIP turned off, so Free agents answer on numbers you buy through the platform. If you only need a number for your agent, you do not need SIP at all.
Do you need it?
Probably not if you are starting out. Many businesses buy a number in InfiVoice, or forward calls from their current line to the agent number. Forwarding is a feature of your phone carrier, so check what yours offers. SIP makes sense when you already have a PBX or SIP gateway and want it to talk to the agent directly. The setup depends on your phone system, so run test calls before going live. Our guide on whether you need to change your number covers the simpler options.
What the site does not say
The site does not publish a step by step SIP setup guide, a list of supported PBX brands or any extra fee for SIP. Ask support before you plan around a specific system. The support guide explains how to reach them.
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. Telephony options are listed on the integrations page.
