I’ve been using 2 - 20 packs of Zulu on a server for months. 4d ago audio just stopped. No changes that I know of to the system. I’m running FreePBXV14 with Asterisk 13.32. Calls connect but there is no audio and the call drops for lack of rtp traffic. I’ve been using a STUN server the whole time with no problems. The IT people say 10K-20K is wide open. Any ideas?
No audio from mobile or desktop. I’ve tried stopping fail2ban. has to be the firewall right?
