Will the DID number be the same for incoming and outgoing calls?

Tip

Quick answer: No. Incoming and outgoing Direct Inward Dialing (DID) numbers are different. Incoming calls on the incoming DID route to your IVR, while call-backs on the outgoing DID follow the existing DID call-back flow. The process of obtaining the outgoing DID remains unchanged.


When should I use this guide?


Read this article whenever you need to confirm how the platform handles inbound versus outbound DIDs—especially before configuring IVR routing or setting up call-backs.



1. Overview


  • Incoming and outgoing DIDs are not the same.
  • Incoming calls on the incoming DID are routed to IVR.
  • Call-backs originate from a separate outgoing DID and follow the standard DID call-back flow.
  • The method for requesting or assigning an outgoing DID does not change.



2. Why can’t I reuse one DID?


The system uses two distinct numbers, so each call direction follows its correct flow. Attempting to place call-backs from the incoming DID skips the defined call-back flow and is therefore unsupported. Keep the numbers separate to ensure proper routing.



3. Expected outcome


After setup:


  • All customer-initiated calls reach IVR via the incoming DID.
  • All outbound call-backs present a separate outgoing DID to the customer.
