AI Feature
Your AI voice agent,
your phone numbers,
one phone system.
Build your voice agent in Vapi, Retell AI or ElevenLabs. Hipcall connects it over SIP, so it answers your numbers, takes an IVR option or covers after hours, and passes callers to your team when they need a person.

Why it matters
The agent you choose
Keep building in Vapi, Retell AI or ElevenLabs. Hipcall doesn't replace your voice agent; it gives it your numbers and your call routing.
Route calls like any extension
Each SIP connection gets an extension number. Point a phone number, an IVR option, an after-hours rule or a transfer at it.
Transfers and outbound calls
Your agent can transfer a caller to a team or a person in Hipcall, and call out through Hipcall with your number as caller ID.
Recorded, transcribed, reported apart
Every call your AI agent handles is recorded in Hipcall and, with transcription on, written down. AI-handled calls are reported separately, so they don't inflate your agents' answered calls or service level.
How It Works
Set up in four steps
- 1
Build your agent
Create the voice agent in Vapi, Retell AI or ElevenLabs.
- 2
Add a SIP connection
In Hipcall, add a SIP connection with your agent's SIP address and give it an extension.
- 3
Connect the other side
In your AI platform, add Hipcall as the SIP trunk with the connection's credentials. Our guides walk you through Vapi, Retell AI and ElevenLabs.
- 4
Send calls to it
Point a number, an IVR option or your after-hours rule at the extension.
Use Cases
After-hours receptionist
A clinic sends calls after 6 pm to its ElevenLabs agent, which answers common questions until the team is back.
One IVR option
An online shop adds "Press 3 for order status" and routes it to a Retell AI agent. Every other option still reaches the team.
Reminder calls
A service company's voice agent calls customers the day before an appointment, using the company's Hipcall number.
