Hi,


You need to verify your routing and security setup here.


If you can not ping from voice vlan, then either your routing is not right. Or you have a firewall in between, and it is blocked.


Either way, you need to verify routing and whether there are any firewalls in between and whether they are configured correctly.


Cheers,


Tim
