International Calling Help - Connected to WiFi, can send/receive Texts but all outgoing calls are “line busy”

Moto X 2nd Gen
Refund Plan
Plan includes 1G data, cell and text


Problem: I’m in France and able to connect to hotel wifi. The phone appears to be working but calls will not go out. I can browse web, send/receive text messages, Skype and perform app updates. When I try to call any US number, I receive “Line Busy” message and exciting busy signal.

I’ve tried many things but nothing will allow the phone to call out without the dial tone. I’ve tried these things with no luck.

  • WiFi in Airplane Mode
  • Setting No Cellular or Roaming services

Nothing seems to be working

Regards

The hotel is probably blocking the ports needed to send and receive calls. Diferent ports than texting.

Try pinging a few of the listed ports using this, http://portquiz.net:8883/:

Look under Open Access - Required Ports & Protocol

These 3 link test are in the proper format for quick test, result will be seen in the 1st section under Outgoing Port Tester
http://portquiz.net:5090 — UDP which is used for call set up
http://portquiz.net:8883 — TCP MQTT for Voicemail, Messaging SMS/MMS and keep-alive messages to RW servers.
http://portquiz.net:6543 — 6000-29999 UDP for voice/audio, full range may be used, single test port should suffice
