IVR fails on a private-network deployment

Extensions work but a call menu/IVR does not complete as expected on a private-address setup.

Detailed solution

  1. Step 1Use one approved test, or a read-only aggregate report. Record the exact time and affected scope before changing anything.
  2. Step 2Trace one lab call from DID to inbound group, call menu, extension, and audio path; have the network owner validate the intended NAT and reachable addresses.
  3. Step 3Change one owner-approved telephony setting only, repeat the same test, and verify both call legs before closing the issue.

Do not do this

Do not expose private services to the Internet or substitute public addresses blindly.
