[asterisk-users] Looking for PRI Card with automatic fail over
Responding to Matt Riddell, M Shokuie, A J Stiles, and Telium Support (all
below)
Thanks for the suggestions, but a separate gateway is a problem in the
design as the configuration is basically:
Carrier --- PRI --- Asterisk (with failover) ---- Legacy PBX
|
- SIP / IAX2 -- our service or remote office
As this is already acting as a gateway adding another box to the mix seems
a bit over kill (unless I can embed it and the asterisk PBX into a 2 U
pizza box). But since most gateways are designed to be used for fail over
servers / PBXs not lines I am not sure that this would benefit us.
So far I have found 1 company that seems to have a gateway card and that is
the beroNet PCI / PCIe Gateway Cards which they say has the card level
failover. I will update the list should this meet the use case.
Eric

You can also chose to TAP the lines as noted above, but you have to ensure that both PRI cards don't go live at once...(if I understand that product correctly). -------------- next part -------------- An HTML attachment was scrubbed...
