Hi FreePBX community.
I have setup a new FreePBX running v15 with Zulu 3. I am wanting to buy additional licensing (i have two trial licenses) for Zulu but before I do I wanted to make sure I can get it all working 100%.
So far internally Zulu works perfectly however when trying to get the softphone on either Windows, iOS or Android connected it fails. But when I disable the FreePBX firewall it works fine. Of course i cant just disable the firewall without dire consequences so I need your advise on what I should be checking/changing on the firewall to get this working.
So far I have changed the Firewall under the services (extra services) section to allow Zulu UC on the Internet interface as well as Local and Other. What else should I change?
I have tried enabling other services one at a time but so far I haven’t had any luck. What am I missing?
