PBX/SIP Integration for AI Voice Agents
AI voice agents on your existing phone system.
We connect voice agents to your PBX and SIP trunks, so calls keep routing through the numbers and infrastructure you already run, not a bolted-on new line.
A voice agent on a separate number is a second phone system.
Most voice agents ship with their own number and their own routing. Your customers already know your main line, and your team already works inside your PBX. Splitting the two means lost transfers and double the admin.
- Customers told to call a different number
- Transfers that drop the caller
- Two systems to monitor and maintain
Three steps from call to launch.
Review the phone stack
We document your PBX, trunks, extensions and current call flows.
Connect and route
SIP trunks are configured and the agent is placed inside your routing, with clear handoff rules.
Test and monitor
We test transfers, failover and peak load, then monitor uptime after launch.

Do we have to change our phone numbers?
No. The agent sits inside your existing routing, so callers keep dialling the numbers they already know.
Does this work with an on-prem PBX?
Yes. We integrate with on-prem and cloud PBX systems over SIP, and confirm compatibility during the review.
What happens if the agent goes down?
A failover path sends calls to your team or voicemail, and monitoring alerts us and you at once.
