Actually, call groups are yet another layer of complexity. Let me try
another explanation.<br>
<br>
With VoIP, the distinction between a call appearance capability and a
line is artificial to an extent. Think of a line as the analog for a
pair of copper wires. Think of a call appearance as call waiting
capability on a line. Well, not exactly, but it works for me.<br>
<br>
In practice, "lines" are identities as understood by the phone and the
SIP server (Asterisk). So when a call arrives, the actual line it
arrives on is indicated in some fashion, depending on the phone. It
probably has separate line buttons and/or LEDs to indicate which line
is ringing or to press to answer. And because there are different
lines, you can specify different behaviors to associate with the lines
for whatever purpose, such as call forwarding, anonymous call reject,
or whatever. Similarly, you may select from the various lines in order
to place an outgoing call which affects, among other things, the call
record and caller ID.<br>
<br>
Whether this is useful to you depends on your organizational
requirements. This leaves aside the question of how you direct calls
to the phone based on your dialplan, which provides another layer of
identity in some sense - a topic for a separate discussion, perhaps.<br>
<br>
On top of this, each identity (line) can have mutliple call
appearances. This simply means that you can have multiple calls in
progress (originated or answered) simultaneously. The mechanism for
managing this varies by phone and configuration.<br>
<br>
Beyond this, Asterisk can be programmed to ring multiple lines for an
incoming call.<br>
<br>
Call groups/pickup groups, are a way of defining associations so that a
user of a line that is not ringing can answer a call directed to
another line (or other lines) which is (are) ringing.<br>
<br>
Does this make sense?<br>

You can make all you phones ring when a certain number is dialed. The
first one to pick up gets the call. I can't think of exactly what this
functionality is called, but I believe there are menus for it in
Asterisk@Home. Perhaps it's call groups?
You need to think of asterisk as a multiplexor -- you have x number of
lines coming in from the PSTN and y number of phones. Not all phones
are active at one time and it is completely indescriminate when it
comes to the next available line. It doesn't matter which line gets
picked up when you dial 9, just that you get an outside line.
You should be able to get your telco to assign the same phone number
on mutliple lines and it will ring through to the next available line
(similar to how a T1 works).
