Avaya NN43170-100 Manuale Utente

Multiple Appearance Directory Number (MADN), also known as Bridge 
Line Appearance, and using Single Call Appearance (SCA) allows 
multiple phones to appear as a single line to the caller. Any of the IP 
Deskphones with an active MADN feature can initiate or answer a call, 
but only one call can be active at a time. However, other clients that are 
part of the same MADN line can join the active call by going off hook.

You can prevent others from joining the call by using the MADN feature to 
make the call private. To make the call private you dial a special code 
(Vertical Service Code) so that the call server knows that the call is 
private. To dial a Vertical Service Code on an Avaya 1165E IP 
Deskphone, you must first initiate a new call by pressing the 

 

context-sensitive soft key, select 

 and then dial the 

Vertical Service Code that is provided by your system administrator or 
service provider.

Note:  The MADN feature is only available when you connect to a call 
server that supports it. Your system administrator manages the 
MADN feature and enables the MADN feature on your Avaya 1165E 
IP Deskphone if required.

When multiple phones are configured with a MADN SCA feature, they 
share one single Directory Number (DN) that is available to the user. An 
incoming call to this DN or to any SIP address of the users of the MADN 
SCA group causes all the phones to ring. Also, any user of the MADN 
SCA group can join a call initiated from any of the phones of that group.

Any user that joins a call with the MADN SCA feature can put the call on 
hold and prevent other users within the MADN SCA group from joining.
