I have moved offices down the street and extended my office network via vlan (old office was using VLAN also). I have two networks one internal and one wireless that I sell wireless service with.

FusionPBX (In the cloud) -> Cable Modem -> PFSense -> VLAN -> Phone.

my phone works fine for a few days on either network then calls stop working, if I switch the phone VLAN to the other VLAN it starts working again. I noticed this issue from my office that is connect of a Ubiquiti wireless link and VLAN extended to my new office.

What happens is the calls ring and I can pickup but no audio in either direction.

here is the pastebin of a call failing then I plugged the same phone into the other vlan and reboot and made a successful call.
