<DIV><FONT face=Calibri>If you are connecting a non-Cisco IP phone to a switch,
you will need to configure the port as trunk. As Cisco phones/switches uses CDP
to work out voice VLAN trunk configuration is not required, though it works
well. Due to the management overhead and the security concerns this
configuration is not recommended.</FONT></DIV>
<DIV><FONT face=Calibri></FONT> </DIV>
<DIV><FONT face=Calibri>When configured with the second option, the switch port
gets configured as trunk, internally, but allows only two VLANs - Voice VLAN and
the access VLAN.</FONT></DIV>

<DIV><BR></DIV>is there anything wrong with having your switch ports configured
as follows?
<DIV><BR></DIV>
<DIV>
<DIV> switchport trunk encapsulation dot1q</DIV>
<DIV> switchport trunk native vlan 14</DIV>
<DIV> switchport mode trunk</DIV>
<DIV> switchport voice vlan 146</DIV></DIV>
<DIV><BR></DIV>
<DIV>Normally I would have them set like:</DIV>
<DIV><BR></DIV>
<DIV>switchport access vlan 14</DIV>
<DIV>switchport voice vlan 146</DIV>
<DIV><BR></DIV>
<DIV>These are 3560's running 12.2 code.</DIV>

<DIV>TIA</DIV>
