will most likely still be able to make and receive calls.

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">However, for the Asterisk
implementation, unless you have a huge ups, you will not be able to make
and receive any call during power failure, since there will be no power to
the Asterisk server. And since all the incoming lines, be it analog lines
or T1/E1 are connected to the Asterisk, these lines wont be able to
function at all. <o:p></o:p></SPAN></FONT></P>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">In some situations, even
though you may have a ups for the Asterisk, network equipment, channel
banks, etc, but your ATA, IP phones which located near to your users and
probably not connected to the UPS, so these devices wont be able to
function. <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Though we can have few analog
pstn lines as standby, but these lines are mostly use for making outgoing
calls rather than receiving incoming calls. For a prolong power failure
situation, these lines cant really help much, so businesses will be
seriously affected. It is possible to contact the telco to re-direct the
incoming calls to the standby analog lines, however, it will generally
take couple of hours for the telco to make the switch and very likely
there will be a fee involve. <o:p></o:p></SPAN></FONT></P>
