You can control the ability to display the caller name on the phone screen instead of the incoming or outgoing phone number. You must configure either the LDAP Directory or the XML directory.

You can add DHCP VLAN options for the voice VLAN of your phones. You configure a predefined DHCP option to learn the VLAN ID.

The phone transfers the predefined DHCP option, such as option 132, using a DHCP request message in the existing VLAN. The server to which the phone is connected, returns the voice VLAN ID. When the phone receives the voice VLAN ID, it releases the IP address in the existing VLAN, switches to voice VLAN, and starts new DHCP settings.

The feature can be used when VLAN info is not available using CDP/LLDP and manual VLAN.

You can register each IP-based phone with an emergency call service provider by supplying the E911 Geolocation information. Registration obtains the phone's location. The location can specify the street address, building number, floor, room, and other office location information. When you dial an emergency number, the emergency service receives the phone location and a call-back number. If an emergency call disconnects, the emergency service uses the call-back number to reconnect to the caller.
