I have configured a Cisco 350 series bridge, as rugged access point, with 3 vlans (native, voice, data), and its respective SSID (admin, phone, guest). Every thing it's ok, conversations between 7920 and 7912, with 7960, 7920, etc... but when I increase the security with a WEP key in the voice vlan , I can not hear any conversation with 7912, "only" between 7920 and 7960 phones. Why?

Configuration attached.

Voice over VxWorks APs isn't supported. Not even sure I still have one lying around that hasn't been converted to IOS or LWAPP.

So without WEP, everything is fine? Able to get DHCP, etc. If so, then port config for trunk mode is ok. WEP would not make some phones work where others don't. If a WEP mismatch, then will be no connectivity to other devices.

Ensure the keys match up.

Also the 7920 only supports Hexadecimal format for WEP (ASCII not supported).

Should probably upgrade to latest VxWorks code as well (12.05).

I have upgrade to VxWorks 12.05, ... and even worst.

Without WEP, I can only talk to 7960 models.

I can ring to 7912, 7905, 7920, (tcp is ok), but after you pick up these phones you only hear noise in both sides. Something is wrong that does not affect 7960 models.

I attach the 350 bridge configuration, and also the switch configuration.

interface FastEthernet0/20

switchport trunk allowed vlan 1,2,17,1002-1005
