[asterisk-users] Looking for PRI Card with automatic fail over

[Eric Klein]

Hi all,

Strange request, I have a customer where we are putting an Asterisk PBX in
front of a legacy (non-VoIP) PBX. One of the requirements it that the
Asterisk PBX have 2 PRI ports (on towards the legacy PBX and one towards
the carrier) with the ability to go to pass through should the Asterisk PBX
(software or hardware level) fail.

I did not see this feature in the Digium, Sangoma, Allo, or OpenVox cards.

Does anyone know of a card that will do this? I know that Digium has an
external box (the r850) that does something similar for 2 PBXs making them
high availability, but in this case I only have the 1 Asterisk box acting
as a gateway and passing some calls out over SIP and IAX2.

Any suggestions would be appreciated.

Thanks
Eric
