You can place calls using Uniform Resource Identifier (URI) Dialing, using the alphanumeric URI address as a directory number; for example, firstname.lastname@example.org. You must enter the URI address to select the contact.
The phone screen displays the call information for the URI call. The phone stores the URI call information in the Call History and the Details page. When you receive a call with a URI address, the URI address is stored in your Call History. Press Redial to call the most recently dialed URI address.
Depending upon how the administrator configures your phone, you may see either the URI or the Directory Number (DN) displayed for the incoming call alerts, call sessions and call history. If the phone is set to display the DN but only the URI is available, then the URI displays. If the phone is set to display the URI and only the DN is available, then the DN displays.
URI calls cannot be placed using the soft keypad.
To place an on-hook call using a URI address, you need to press the ABC softkey to switch the keypad mode.
To place an off-hook call using a URI address, the URI address must be stored in your Call History or Speed Dial list.
When you enter a URI address to place a call, do not pause for more then 10 seconds between key presses. After 10 seconds of inactivity, the phone assumes that it has the complete address and attempts to place the call.
When you dial or receive a call through URI dialing, the call window and incoming call alert display the complete URI address.
When you enter a URI address, the maximum length is 254 characters. You can enter the complete domain name to override the default domain.
URI dialing works with the other features of your phone:
You can configure a URI address as a speed dial entry to place a call.
You can configure the Call Forward All destination using the Speed Dial or Call History entries.
You can initiate a conference call and add multiple parties using URI Dialing if the URI address is stored in the Speed Dial list or Call History.
You cannot use URI addresses during Meet Me conferences or for Group Call Pickup.
You can initiate a transfer call using URI dialing if the URI
address is stored in the Speed Dial list or Call History.
You can monitor the state (in-use or idle) of a call using URI Dialing associated with Speed Dial or Call History.
You can initiate URI Dialing when a busy or unavailable party becomes available.
You can hide the display of the URI address information.
When the phones are connected to the Cisco Unified Communications Manager Express and Survivable Remote Site Telephony (CME/SRST), the URI Dialing functions are disabled. The ABC softkey does not appear on the phone screen.
