I’m struggling to get some Yealink phones to connect to a hosted FreePBX server. The Yealink phones are behind a pfSense firewall, with default/out-of-the-box config (version 2.5).
I’ve tested these phones behind a consumer ASUS router, and they have no issues registering with the FreePBX server.
After tinkering with NAT rules for an hour, I’m looking for some guidance on what configuration changes I can make in pfSense to allow these phones to successfully connect.
Happy to provide additional details as needed.
