Step 2 In the Enable URI Dialing 1 , select Yes to enable alphanumeric dialing.
In the phone page, you can add a string on a line key in this format to enable speed dial with alphanumeric
dialing capability:
fnc=sd;ext=xxxx.yyyy@$PROXY;nme=yyyy,xxxx
For example:
fnc=sd;ext=first.last@$PROXY;nme=Last,First
The above example will enable the user to dial "first.dial" to make a call.
The supported characters that you can use for alphanumeric dialing are a-z, A-Z, 0-9, -, _, ., and +. Note

Configure a Paging Group (Multicast Paging)
You can configure multicast paging so that users can page all the phones at once or page a group of phones
without involving a server. On the Configuration Utility page, you configure a phone as a part of a paging
group and can subscribe them to the same multicast address. This enables users to direct pages to specific
groups of phones. When you assign each paging group with a unique number, the user dials the paging group
number to start paging. All phones that are subscribed to the same multicast address (also configured on the
Configuration Utility page) receive the page. The user hears a paging tone of three short beeps when there is
an incoming paging call.
Keep these things in mind:
• Your network must support multicasting so that all devices in the same paging group are able to join the
corresponding multicast group.
• Paging groups must use even-numbered port numbers.
• If the phone is on an active call when a group page starts, the incoming page is ignored.
• Group paging is one way and uses the G711 codec. The paged phone can only listen to the call from the
originator.
• Incoming pages are ignored when DND is enabled.
• When paging occurs, the speaker on the paged phones automatically powers on unless the handset or the
headset is in use.
• If the phone is on an active call when a group page starts, the incoming page is ignored. When the call
ends, the page is answered, if the page is active.
• When multiple pages occur, the pages are answered in chronological order. Until the active page ends,
the next page is not answered.
