Why this use case exists

Many agencies and operators purchase phone numbers inside Retell. Historically, outbound setups required importing numbers directly from providers like Twilio/Telnyx, which created friction. Knotie now supports Retell phone number import, enabling:
  • Use of Retell-managed numbers in Knotie
  • Customer assignment + credit tracking in Knotie
  • Outbound dialing from external systems (GHL, forms, custom webhooks)

​
What you’ll achieve

  • Import Retell phone numbers into Knotie Partner Portal
  • Assign the number to a customer
  • Assign a Retell agent to the number (Outbound enabled)
  • Generate an outbound webhook key (owk_...)

Operational notes

  • If you are using Retell-purchased numbers, billing for telephony may remain with Retell.
  • Knotie still provides the partner/customer management layer: assignment, tracking, and quota/credit enforcement.
