Users, I was able to install Freeswitch in Azure and talk with PC Sip Emulators without any problem. The issue I have is what when I try to call 1877 number and others standard nubmers and I got a NO Answer from the Twilio counterpart. I did the same outside Azure and worked fine. I opened the same firewall ports en both cases and proper endpoints. Default config with changes to run under Azure. Any idea what to check?
