Deploying Voice Over IP (VoIP)
For a complete list of all PoE commands, see the Dell Networking OS Command Line Reference Guide.
Current VoIP phones follow the same basic boot and operations process:
1 Wait for an LLDP from the Ethernet switch.
2 Obtain an IP address from a dynamic host conguration protocol (DHCP) server.
3 Send an LLDP-MED frame to the switch.
4 Wait for an LLDP-MED frame from the switch and read the Network Policy TLV to get the VLAN ID, Layer 2 priority, and DSCP value.
5 Download applications and software from the call manager.
6 After the conguration completes, send voice packets as tagged frames and data packets as untagged frames.
The following shows a basic conguration for a deployment in which the end workstation plugs into an IP phone for its Ethernet
connection.

Creating VLANs for an Oce VoIP Deployment
The phone in the previous gure requires one tagged VLAN for VoIP service and one untagged VLAN for PC data, as shown in the
following example.
You can congure voice signaling on the voice VLAN but some implementations may need an extra tagged VLAN for this trac.
