[Amportal-users] Dual broadband connections

General Help
1

It’s easy enough to add an extra ethernet card, and have it connected to a separate ISP. But you can really only have one default route, or at least one route for a given destination. For example, you can route just your ITSP (telephony provider) through one connection (by their IP), and then everything else (like web traffic) through another connection. By writing a small script, you can detect when the connection goes dead (i.e. ping the ITSP) and then change the routing tables. Here’s the catch: the ITSP needs to be able to deal with you switching IP addresses (you can’t be static) and you will not be able to keep a live conversation going when it switches over. Everything has to be re-registered and calls started up again. The only way around that is to have your own private IP address, and have two providers that are willing to route to you simulataneously (much more cost).

Has anyone set up 2 ethernet ports on an Asterisk box for redundant IAX2 or SIP trunks. I have 2 seperate broadband connections and I would like to use one as a primary and one trunk as a backup. :roll:

Can you get around this issue by assigning 2 trunks with diferent routes (maybe even register 2 trunks on the other end with seperate static IP addresses). Then in the outbound rules have it switch to the other trunk, when it goes out of service. This is what I do with ZAP PSTN trunks. If one goes down, it selects the next one.

Having two trunks works. Wouldn’t matter if each connection was static IP or not, so long as the ITSP can deal with you being a dynamic address (generally not an issue). Inbound routing might be difficult though, unless you manage to arrange two distinct trunks with the same ITSP and have them tied together for the same set of DID’s.
