asterisk users - Aug 2015 - Looking for PRI Card with automatic fail over

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

There was a product called something like red box or similar that I saw around 5
years ago. Probably not entirely helpful but maybe Google will help.

Kind regards,

Matt

Hi there,

Using Sangoma Vega400 gateway you'll have what is called resilliency which
is exactly what you are looking for.

Regards.

Use a 4-pole change-over relay to switch the PRI connection either to the 
Asterisk box if it gets some sort of "heartbeat" signal from the
computer
(say, toggling one of the lines of a printer port, if the motherboard still 
has one),  or the old PABX?

You might have to do some mean, down and dirty low-level programming, to embed 
your heartbeat-generating code in Asterisk's idle loop; but the Source Code
is
out there, if you fancy the challenge .....

Building on the answer above, have a look at ESL labs - who make such a 
relay that can bypass the PRI to the Asterisk server.  As well, have a 
look at HAAst (www.telium.ca) which can monitor Asterisk and then 
control the ESL relay to bypass Asterisk in case of failure.

Hi,

What you need is PRI TAP (also called SWITCH box)

Check this one
