MD Evolution – Dialog 4223 Professional

Notes: 
Typically, the time limit for this service is 20 seconds. After 
this time limit expires, the service is automatically ended, 
whether you are the requestor, or whether your extension is 
part of the targeted broadcast group.
It is your system administrator’s job to define to which 
broad-
cast group(s) you belong. This is also the case in relation to 
the specific right necessary for initiating a broadcast to any 
group whatsoever, whether or not you belong to it.
Your facility may have up to 5 broadcast groups, each of 
which may contain up to 32 members
Personal Group Services
While it’s not really a group service, you also have access to a 
personal group, which is designed for grouping various extensions 
that may be assigned to you (up to 5 extensions) – for example, 
your Dialog 4223 Professional extension, and a DECT cordless 
phone.
The specific services offered to you are as follows:
You can be contacted through just one number, common to 
your entire personal group.
When you place a call to any party, you are identified by your 
personal group number, no matter what extension you use to 
place your call.
An incoming call is presented on all of your personal group’s 
extensions, allowing you to answer it on any of them. If all 
extensions in your personal group are free, they will all ring 
simultaneously. If you have an ongoing call on any given 
extension, the call is presented to you on that extension in 
the usual way (call waiting tone, etc.) On each of the other 
extensions – when it is possible – the call will be presented 
with silent ringing, a line key will flash, and the usual call 
information will be displayed on the screen.
You have the option of carrying out a simplified call transfer 
between extensions within your personal group (other than from 
a Dialog 4425 IP Vision or Dialog 4422 IP Office extension). To 
do so, simply place your current call on hold and replace. The 
call is then represented on all of your personal group extensions; 
therefore you may pick it up on any of them.
