How Call Sessions Work
Any call activity is referred to as a call session. Call
sessions can be tracked on the Call Progress window.
(See “Call Progress Control” on page 117.)
Call sessions are also recorded in the call log. (See
“The Call Log Window” on page 135.)
Each handset operation involves one air channel. A
single call session uses one or two air channels,
depending on the nature of the call:
•
An external call (incoming or outgoing) uses a
single channel.
• A call from a handset to CyberGenie also uses a
single air channel.
• Calls between two handsets, however, use two air
channels, one for each handset.
Your CG 2400 system supports up to six
simultaneous air channels for a maximum of three
handset-to-handset sessions if there are no handset-
to-CyberGenie calls or external calls at the same
time.
The system also supports a maximum of two
simultaneous handset-to-CyberGenie calls.
Incoming and Outgoing Calls
All calls that you receive or place with the handset
are either external (involving an outside line) or
internal (handset to handset, or handset to
CyberGenie).
You can park a call (put it on hold so another user
can retrieve it), retrieve a parked call, or transfer a
call to another user.
You can also send an unwanted call to a rejection
message.
