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

​
1. SIP Trunk

  • How It Works: You share your SIP credentials (server, username, password). Callupgrade.ai 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 Callupgrade.ai 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 Callupgrade.ai usage fees.
