[Asterisk-Users] How to make/recieve call using asteriskwhenthereis a power failure?

[Steve Totaro]

build your server with one of these and then run a cable to your car's lighter.

  Have a look at http://www.twacomm.com/Catalog/Model_PF-6A.htm

  As for T1/E1, you have a big business, get a decent UPS and a generator.

    We use several Dell 2650 servers.  Order them with the dual DC power supply option.
    Buy a row of -48 batteries and a -48 power source, your servers will stay up for hours.

      Hi,

       

      I am supportive of the asterisk, but I have some concern, though the concern also applies to traditional pbx as well. Hope someone can shine some light into it. Thanks.

       

      During a power failure situation, analog pstn lines that connect directly to the analog phones will most likely still be able to make and receive calls. 

       

      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.  

       

      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. 

       

      And even if you have a ups, after an hour or two, your uos will drain out, so how? 

       

      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. 

       

      I read from this forum that many asterisk implementations had been carried out, I wonder how these implementation take care of the power failure situation? Can someone share the views and implementations?
