[Asterisk-Users] Grandstream and VLANs

[Wojciech Tryc]

I need tagging as I will have also PC's on the hub connected to the same 
port on the switch. PCs will be on a separate VLAN. As I have to tag one 
device I prefer to tag phones (apparently supported). Again, Cisco phones no 
problem (as expected) :)
Anyone tried Grandstream's VLAN tagging?
