As per DocCD, at
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3560/12240se/scg/swvoip.htm
*From the 3560 Config guide, Note *Voice VLAN is only supported on access
ports and not on trunk ports, even though the configuration is allowed.
It may work, but it is not supported to configure a voice VLAN on a trunk
port.
and
http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.2_25_see/configuration/guide/swvoip.html
From the 3550 config guide,"You should configure voice VLAN on switch access
ports."
Regards,
Joseph.
