FreePBX + Sangoma phone VLAN trunking config

First post. I guess it'll be a simple one.

Here is how I got Sangoma S500 phones to act as switch for a computer while keeping VoIP and Data traffic on their respective VLANs:
  • Create a separate Voice VLAN with it’s own DHCP scope that hands out IPs to the phones 
  • A static on the same subnet for the PBX.
  • Set each phone port on the switch to trunking.
  • FreePBX Endpoint Manager template for the phones:
    • WAN port of the phone as tagged Voice VLAN --> plug into switch
    • Second phone port tagged as Data VLAN --> plug computer in
  • Now both voice and data traffic come through one switch port but traffic is already tagged and segregated.
Done.

Here's a helpful link that explains some concepts: https://wiki.freepbx.org/display/PHON/VLAN
