I’ve installed FreePBX 220.127.116.11 on a Vultr server. I went through the FreePBX firewall wizard and used the default/recommended settings. I set up 2 extensions and 1 voip.ms trunk.
My problem is, I cannot get any audio at all. I have set up 2 extensions, registering with a Mitel phone and a cell phone on LTE using the Zoiper app. Both register and can call each other, but there is no audio. When I do an echo test (*43) or a speaking clock (*60), I don’t get any audio either.
I want to say this is some kind of firewall/port problem, but as the Vultr server has a public IP and the Vultr firewall is off, I’m not sure where to look.
