Covid-19 is requiring employees to work from home. I am tasked with getting our working office LAN IP phones (Sangoma S305) from employees desks to their home networks. Our FreePBX server VM is parked on our WAN with a static routable IP (98.xxx.xxx.110). Office phones are set as DHCP clients that get IP reservations handed to them from a Microsoft DHCP server when connected on the LAN (192.xxx.xxx.80-94). Their phone configs point to 98.xxx.xxx.110 and connect through our PFsense router VM to (98.xxx.xxx.105). Connectivity > Firewall > Interfaces > eth0 default zone is Internet with 98.xxx.xxx.110/28 to encompass the FreePBX and PFsense IPs.
In my testing I have connected a office phone to an external network that provided it with a 10.xxx.xxx.112 IP. It gets dialtone and looks like it is working, but when I dial out to my cell phone I am greeted with silence. Connectivity > Firewall > Networks I set 10.xxx.xxx.112/32 to Trusted and saved. I rebooted here for good measure: Admin > System Admin > Power Options > Reboot. My test phone behavior did not change, I could not get an outbound connection.
What logs or configs should I look at to troubleshoot this problem?
