NBX and VLANS and priority on WAN

Questions



First- I am having NO audio issues on my LAN.



But I am on the WAN, even when set to use the lowest bandwidth  uitilization , codec G729.



So-



Question 1--



If I am using the switch  ports on the back of the phone for computers.



Will this still work if I make  a voice VLAN ?



Question 2--



If no LAN issue, is it worth it to make a VLAN?



Question 3--



I am currently running 3300's and 4400's for switches-- Level 2.



I am using  my 4400's as core switches, they are set up to priorotize the nbx traffic.



What happens to the priority when it goes to the WAN on VTL's. 



Is it converted to a Level 3 priority?



 



Thanks

whatever vlan the ports on the switches are assigned to is what vlan the devices will use

No



All packets are encrypted so no security issues . No garbled speech or distorted audio so no need to segment the traffic .

802.1Q = Quality of service


802.1p = Prioritizataion ( layer 3 traffic )



Is it converted to a Level 3 priority? not normally , but yes as we ( NBX ) can put a tag on it for prioritization



IP VLan enabled is the feature on the NBX .
