[asterisk-users] Asterisk - Failover System

[Alex Balashov]

Depends on your conditions for failure.  If you are simply looking to 
get around hardware failures or other physical conditions which result 
in the T1s going down, you can use a reliable piece of ISDN gateway 
equipment in front of the Asterisk boxes that pushes SIP out the other 
end and configure it to fail over calls to a second VoIP peer.  It 
creates a single point of failure, but one which is far, far more 
unlikely to fail than PC hardware.

Or, you can use a DS1-level DACS that can protection switch the T1s to 
another port.

Ultimately, your failover options are limited if you have T1s physically 
going into an Asterisk box with a T1 card.  Your best bet is to somehow 
separate the two components;  then, you can get the proper redundancy 
measures implemented on both sides in ways that are most native and 
technologically appropriate, instead of coupling them in a way that 
makes them difficult to divest.
