Multiple Call Appearances In Sls Mode; Hold In Sls Mode - Avaya G250 Administration

Multiple call appearances in SLS mode

When a gateway is in SLS mode, three call appearances, each with limitations, are supported:
The first two call appearances are for incoming or outgoing calls. The first call appearance
●
is the default.
The third call appearance is for outgoing calls only.
●
Note:
"First", "second", and "third", refer to the order in which you use call appearances,
Note:
not the order of the call appearance buttons on your phone.
For example, if User A chooses the third call appearance to dial User B, and then User C calls
User A, which is sent to the first call appearance. In this situation, a subsequent inbound call to
User A will be denied (busy) because the first and third call appearances are in use, and the
second call appearance is only available for outbound calls.

Hold in SLS mode

Using the Hold feature differs by user and by phone type, and the same is true of the Hold
feature in Standard Local Survivability (SLS) mode. Some users return to a call on Hold by
pressing the call appearance button, however Communication Manager has an administrable
parameter that allows users to release a call on hold by pressing the Hold button a second time
(if only one call is held). The Hold feature also works differently in
Analog phones
The Hold feature in SLS does not support:
Music on Hold
●
Local mute on analog phones
●
Specialized treatment of E-911 calls
●
Call Hold indicator tones

DCP and IP phones
When a media gateway is in the survivable mode, you can release calls on Hold on all DCP and
IP phones by either:
Pressing the Hold button a second time (if only one call is held)
●
Pressing the winking call appearance button
●
Analog phones
Newer analog phones (for example, Avaya 62xx series) have buttons with specific functions for
placing a call on Hold:
Hold button sends the hold message to the server
●
Flash button sends switchhook signal to the server
●
Switchhook (receiver on/off hook) sends disconnect signal to the server
●
in the survivable mode.
