[Asterisk-Users] GXP-2000

[Daniel Salama]

Would you mind telling me how to setup the GXP-2000's VLAN/QoS  
settings with the DES-1226G? I just purchased the DES-1226G and want  
to make sure I setup it up right. I don't have the ability to run  
separate wiring for the PC and the phone and that's why I need this  
help.

Thanks,
Daniel
