Telerivet can integrate with any voice-over-IP (VoIP) provider or device that can send incoming calls to a SIP URL.
This functionality makes it possible to use local phone numbers for your IVR system, even in countries where virtual numbers aren't available via Twilio or Vonage.
How it works
To connect your VoIP provider to Telerivet, you can connect it to a Twilio SIP Endpoint, then connect Twilio to Telerivet.
When you receive an incoming call, your VoIP provider will connect to Twilio via SIP, which will then trigger the IVR call flow defined in your Telerivet account.
Twilio charges a small per-minute fee for voice calls using the SIP interface feature, in addition to the cost you pay to your VoIP provider.
Outgoing voice calls can use either your VoIP provider or Twilio.
