It's not clear exactly what you want to do. My best guess is that you are looking to be able to make calls via some other route if/when your primary VoXaLot proxy is having problems for some reason. Is this correct?

If so, than the ability to do this (and how it's done) depends entirely upon what VoIP equipment you own/use, and how you have it configured. Depending upon where you are calling, there are certainly alternative ways (other than VoXaLot) that you can reach there (for example, send the call directly to your provider, vs sending it to VoXaLot and have your VoXaLot dial plan decide to send the call to your provider). And even VoXaLot itself has some redundancy built in, as we have multiple servers (so in theory if the VoXaLot server closest to you was down, you would still have the option to send the call to some other VoXaLot server that may be up).

But the thing is, if/when you want to reroute the call, you need equipment that can handle the reroute of the call. So if you are trying to provide a "backup" to your VoIP calling (for if/when your VoXaLot server is down), the only real way to do this would be to handle the "backup" directly in your VoIP equipment yourself. And since VoIP equipment varies a lot in what "backup" options (if any) that it supports, we don't even know if your equipment would support such "backup" options, much less how you would configure them on your specific equipment.

NOTE: You didn't say that you use LinkSys VoIP adapters, but since many do there is a chance you also use such equipment (so I'll give the answer for LinkSys equipment, below). With LinkSys SPA-xxxx adapters, you can't really have a true "outgoing backup", because there is no way to tell the LinkSys-xxxx adapters to send the call one place if/when the proxy is up, and elsewhere when it's down. However, the LinkSys adapters do have the ability (via customizing the dial plan) to give you the option to send the call to an alternate proxy based upon what you dialed at call time. So if you customize your dial plan to have a unique dialing prefix route calls to an alternate proxy (for example, a different VoXaLot server), you would get a partial "manual backup", in that you would be able to use the alternate dialing route whenever you wanted to (by dialing the prefix you setup your your dial plan). But that still wouldn't give you a true automated "backup", because the adapter would still try your normal way of calling if/when you dialed "normally" (even if/when your normal VoIP proxy is down for some reason).

NOTE: Almost all of the LinkSys VoIP adapters let you override your proxy via the dial plan (so almost all LinkSys adapters would give you the option to select your VoXaLot proxy by how you dialed, assuming you customized your dial plan for this). But most of the LinkSys adapters (and this limitation does include the very common/popular PAP2) don't give you the option to override your line's userID and password (the notable exception to this rule is the SPA-3102, which does have the ability to override the userid and password from the dial plan), which means that you generally won't have the "backup" option to send the calls directly to your VoIP provider (bypassing VoXaLot completely). However, even with the PAP2, you should (if you want to get that fancy) be able to setup your "dial plan" to let you choose (by how you dial) which of the 3 VoXaLot proxies to send the call via how you dialed the call (presumably you would want the "default" dialing approach connect you to the VoXaLot proxy that is nearest to you on the internet).
