a newbie to Asterisk; need help understanding three-way conferencing &
<BR>call-transfer features implemented over standard extensions i.e. on a
<BR>TDM800P card (4 FXO + 4FXS)<BR><BR>In Asterisk I have observed that if an
extension is already participating in <BR>an active call (e.g. Ext A & Ext B
communicating):<BR><BR>1. An incoming call to one of these active extensions
would be presented <BR>with call-wait beeps (e.g. Ext A receives call-wait beeps
as Ext C is <BR>attempting to call Ext A).<BR><BR>2. The call waiting may be
answered by pressing Hook-Flash, placing the <BR>previously active call on hold
(e.g. C answered; A & C communicate; B placed <BR>on hold).<BR><BR>3. The
calls could be toggled by subsequent Hook-Flash's (e.g. A & B
<BR>communicate; C placed on hold).<BR><BR>Queries:<BR>1. If the extension which
received call-wait beeps hangs-up then the call <BR>waiting/the call placed on
hold returns as a new call. I was expecting the <BR>call to be transferred (A
hangs-up, B & C communicate), how could the call <BR>be transferred? I
expected this feature to be available in Asterisk as this <BR>is a very normal
feature available on any PBX and used extensively in Call
<BR>Transfer.<BR><BR>2. How could the extension that received call-wait beeps
initiate a <BR>three-way conference with the other extensions (A, B & C in
three-way <BR>conference)? I expected this feature to be available in Asterisk
as this is <BR>a very normal feature available on any PBX and used extensively
in 3-way <BR>Call Conference.<BR><BR>Regds.<BR>Varun
