New Special Destinations Available in Outbound Voice Profile

21, Jan 2026

We’re excited to announce that four new special destinations are now available in the Outbound Voice Profile settings. Customers can now control whether calls to these additional international destinations are allowed—directly from the Mission Control Portal or via the Telnyx API.


What’s New

The following special destinations have been added to the Outbound Voice Profile under Special Destinations:

  • International Maritime Satellite (inmarsat)
    Satellite communication services for maritime vessels

  • Global Mobile Satellite System (gmss)
    Mobile satellite communication services

  • International Networks (intlnetworks)
    International network destinations

  • Universal Personal Telecommunications (upt)
    Personal telecommunications services

These destinations join the existing Universal International Toll-Free (uitf) option that was previously available.


How It Works

Via Mission Control Portal

From the Outbound Voice Profile page in the Mission Control Portal, customers can toggle these special destinations on or off. When enabled, calls to these destinations will be allowed for users on that voice profile.

Steps:

  1. Log in to the Mission Control Portal
  2. Navigate to your Outbound Voice Profile settings
  3. Go to the Allowed Destinations tab
  4. Find the Special Destinations section
  5. Toggle the desired destinations on or off based on your business requirements

Via API

Customers can also manage these special destinations programmatically using the Telnyx API. The whitelisted_destinations field in the Outbound Voice Profile accepts the following values for special destinations:

  • Universal International Toll-Free: uitf
  • International Maritime Satellite: inmarsat
  • Global Mobile Satellite System: gmss
  • International Networks: intlnetworks
