I have a 3CX installation on DigitalOcean and have Yealink T29G phones configured via Flowroute. Calls can be made and received but no audio is passing. I've set each extension to have it's own range of ports (5065 SIP and 14000-14019 RTP for extension 100, 5066 SIP and 14020-14039 RTP for extension 101, etc). I then went into my DigitalOcean dashboard and attempted to configure the Firewall to allow those ports and port ranges but when I check the port (https://www.yougetsignal.com/tools/open-ports/ ) I am being told the respective ports are still closed. Some ports (5060, 5090) reply that they are open.
I've tried adding rules to iptables but still can't get it to allow those ports to be visible and thus callers can hear or be heard.
I really need to get this figured out but haven't gotten anywhere yet. Anyone familiar with 3CX on DigitalOcean using STUN to configure Yealink T29G phones?
