[Asterisk-Users] What happens if quadbri or octobri loses power - do they have power failure feature ?

[Robert Rozman]

Hi,

I mistakenly posted this to Dev list....

I wonder if I use quadbri or octobri cards to insert Asterisk between ISDN
PBX and ISDN line - if power of Asterisks fails - will those card connect
PBX directly to ISDN line ? If not are there any other simple switching
devices, that would do this (in power fail it will connect ISDN PBX to ISDN
lines directly) ?

Thanks in advance,

regards,

Rob.
