Many customer configurations base the room telephone extension on the room number 
by adding an extra leading digit. The PMS Insert/Delete Digit feature allows users to 
delete the leading digit of the extension in messages. The feature is useful for a hotel 
that has multiple extensions sharing an extra leading digit in front of the room number. 
The leading digit is automatically inserted when the message goes to the PBX.

NOTE:
The PMS interface supports 3-, 4-, or 5-digit extensions, but prefixed 
extensions do not send the entire number across the interface. Only the 
assigned extension number is sent. Therefore, you should not use prefixed 
extensions for numbers that are also going to use the Digit to Insert/Delete 
function.

Allows hotel staff and guests easy access to internal hotel/motel services and 
provides the capability to associate room numbers with guest room telephones. 
The feature provides the following dial plan types: single-digit dialing, prefixed 
extensions, and mixed numbering.

DEFINITY ECS inherently handles high-volume multimedia transmissions effi-
ciently and will continue to add multimedia features to improve on its multimedia 
capabilities.

Multimedia calls are initiated with voice and video only. Once a call is 
established, one of the parties may initiate an associated data conference to 
include all of the parties on the call who are capable of supporting data. The data 
conference is controlled by an adjunct device called an Expansion Services 
Module (ESM).
