[Asterisk-Users] Grandstream and VLANs

[Colin Anderson]

As it should. As a stupid work-around, you could possibly put *everything
else* on a seperate VLAN from the phones and you would have kind of a
reverse-VLAN which would have the net same effect, this would be fine for 10
PC's but 100? 200? fuggedaboutit.

Yes, I guess I will have to start looking at the packets.
BTW: if I set the port to which grandstream is plugged to untagged vlan and 
leave the default VLAN 0 on the phone then everything works just fine....
