Quad PRI Failover

While I would normally not post any commercial products, I thought this one was pretty useful, even though they could have made their mail a little less spammy.

Basically the unit connects to two Asterisk servers (one of which is a hot standby). They send calls through the unit to the quad span in Asterisk. Once the calls have been going for a while, they kill zaptel. The res_heartbeat.so module then means that the unit switches the quad span across to the other Asterisk machine. The spans come up and calls start processing as normal again.

They've made a video of it in operation.

As I said, I'm not too sure of their marketing method (you buy two Sangoma or Digium cards and they give you the unit for $1), but it's a product which is immediately useful (at least for me).

Update:

> I saw your message on the Asterisk-biz Mailing list, and wanted to respond. You can, absolutely, buy the unit with one or no cards.

> It's available at this URL

> P.S., You can also use the original link (products_id=3) to Order the unit and just one card, and still get 50% off on the unit.

There is another product which does something similar. Its called like the red box or something. I can never remember the name right and always end up scouring google for it.

Yeah, close, it was called Red Phone - basically sends the calls to Asterisk using TDMoE.

While looking for Red Phone I came across this one which is another similar unit.
