Learn how to integrate Larsaai.com with your existing PBX or VOIP infrastructure through SIP trunks

For businesses with existing PBX or VOIP infrastructure, Larsaai.com can integrate through SIP trunks or direct connections:


1. SIP Trunk

  • How It Works: You share your SIP credentials (server, username, password). Larsaai.com configures a trunk internally.

  • Inbound/Outbound: AI can pick up inbound calls from your PBX or place outbound calls using your existing number ranges.


​2. Caller ID Forwarding

  • If your PBX already handles call routing, pass the call to Larsaai.com only when certain conditions are met (like after IVR selection).

3. Hybrid Model

  • Some advanced setups keep human agents on your PBX but leverage the AI for high-volume or after-hours calls.

  • Example: During business hours, normal agents handle calls. After hours, calls route to the AI assistant via SIP trunk.

4. Things to Note

  • SIP sometimes requires opening firewall ports or whitelisting IPs.

  • Carrier charges from your PBX provider still apply, plus any Larsaai.com usage fees.


Tip: Contact support for guidance if you’re new to SIP or PBX integration. We can assist with the config steps.
