Callupgrade.ai lets you connect three different kinds of phone numbers to your AI assistant:
  1. Normal (Dedicated) Numbers
    • Rented directly from Callupgrade.ai.
    • Can be used for both inbound and outbound calls.
    • Typically charged as a monthly rental, with the ability to handle multiple parallel calls on a single number.
  2. SIP Integration (VOIP/PBX)
    • Connect an existing VOIP or PBX number via SIP.
    • This setup allows you to keep your existing numbers while benefiting from Callupgrade.ai’s AI.
    • Works for both inbound and outbound—but requires you to share SIP credentials or trunk details with us to configure.
    • To submit a request, contact us through the chat widget in the bottom right corner of the screen inside the app.
  3. Caller ID (Outbound Only)
    • When you already have a phone number (e.g., your personal or business line) but don’t want to port it or integrate via SIP.
    • You verify ownership (via OTP or a short call) so that number can appear on people’s caller ID.
    • Inbound calls won’t be answered by the AI if you use Caller ID alone—it only masks the AI’s outbound calls.

Choosing the Right Option

  • If you need inbound and you don’t already have a VOIP solution, consider renting a dedicated number.
  • If you have an established PBX or VOIP provider, use SIP integration.
  • If you just want to do outbound calls showing your existing phone line, pick Caller ID.
