I have a small doubt regarding the Switch for Voip Configuration, I always setup the voice vlans and Switch 2960 and 2950, but now I'm working with 3560 series switch and I found for add port to the Voice Vlans all the ports has to be Switchport Mode Trunk and Switchport trunk encapsulation dot1q. Why on this particular switch this type of configuration is need it.
For Cisco IP Phones, you will not need to use the 'switchport mode trunk' command. You should be able to use the standard voice vlans. If this is a thrid party phone, you may need to configure the switchport as a 802.1q trunk.
Trunk mode issue is due to the fact that these ports accept tagged info from IP phones apart from untagged from PC, prior to this version we can configure it in access mode, to be very specific the same is in “a quasi access” state to engage both types of packets.
Encapsulation has to be specified because these switches support both ISL and IEEE standards, hence to avoid conflict explicit configuration commands as to be included between these standards
