[Asterisk-Users] Grandstream and VLANs

[Wojciech Tryc]

I am having hard time to get VLAN tagging working with Grandstream 101 
phone. As soon as I enable tagging on the switch and configure the phone to 
tag packets with corespodning VLAN ID #. I can not even get IP anymore from 
my DHCP. I have to reset the phone to factory default. I've tried different 
Grandstream phones with various firmware without any luck.
Obviously, the same idea works great with Ciscos
Any ideas?
