I have a feeling the answer is likely something simple but I’m still confused. I’ve got Zulu UC working quite well on my iPhone but it only seems to work on WiFi connections. The minute I switch over to the cellular network it can no longer reach the server. Our PBX is cloud hosted so I’m never on its LAN so it doesn’t appear that it is a firewall issue. I’m in the US using Verizon Wireless so is it possible that they are port blocking? I’ve tried connecting via VPN on my phone which is how I had been using Bria, but that did help. I assume because at that point I’m tunneled in and can’t use a FQDN.
Has anyone else run into this issue or have any ideas of what might be causing it?
