I was wondering if it is possible to register an ATA (my SPA-2100 specifically) with FWD, Sipphone or Voxalot and yet in my dial plan make outbound calls directly to my callout provider (even though they use a username/password)? I know Voxalot offers a way to use third party outbound providers internal to itself (while FWD and Gizmo Project do not), but I've found Voxalot's implementation to be somewhat buggy and I am not able to make three-way calls using Voxalot's internal solution.

(I apologize if this is already covered somewhere in the 30 page dial plan topic but that was too hard to navigate usefully.)

For instance, if I change this in my dial plan:
1[2-9]xx[2-9]xxxxxxS0

To this:
1[2-9]xx[2-9]xxxxxxS0 <userass@voip-provider.com>

And assume I am registered on that line with FWD (or one of the other two), and that "voip-provider.com" is some third party fee-based outbound calling provider. Would this change mean generic 11 digits North America calls could go out through that 3rd party provider and it would work correctly?

If I need any syntax changes to allow it to work let me know.

Not on the 2100, no. That feature is what the 4 "gateway" slots in the SPA3000 and SPA-3102 are for...

Why does SipBroker work on a SPA-2100 but not this? SipBroker is added to my device with the following dial plan:
*xxx[x*]. <:@sipbroker.com>

This places the call through sipbroker.com instead of the 'main' SIP proxy the 2100 is registered to. I know that works. So what is the difference to the device if instead of <:@sipbroker.com> I put <userass@voip-provider.com>? It looks like the same sort of dialing logic to me. Yet I just tested what you said and you seem to be right, I cannot add <userass@voip-provider.com> to the end of the dial string and get it to use that. It just tries to make the call through Gizmo Project.

Because SIP Broker doesn't require a username and password.

Remember, you asked about using multiple providers that require a username/password. And so the example with "SIP Broker" doesn't count, as SIP Broker doesn't require a username/password to use it.

Most LinkSys/Sipura adapters will let you override the "proxy" (with the <:@proxy> syntax in the dial plan). But in general you can't use that "trick" to override the username and password). So this is mostly just useful for "open proxies" (such as SIP Broker) that don't require a username and password. But that doesn't help you use a different VoIP account that does require a username/password to be sent! To use multiple "closed proxies" (that require a username/password), you have to use one of the adapters that allows you to specify the username/password for a non-default proxy (and that's not the 2100)...

I think I am starting to regret owning a SPA-2100 rather than either a SPA3000 (i.e. a SPA-3102) or a SPA-1001 (or indeed both of them at once). Thank you for your help again Draco, I am disappointed that what I wanted to do was beyond my hardware's capabilities but at least I have a clearer picture in my mind now what my device (and my dial plan) is capable of when pushed to its limits. Now I am becoming more tempted to install Asterisk@Home on an old Pentium box and have everything I want and more as I leave it to manage all my inbound and outbound registrations. If only the Linux environment didn't seem so daunting to a Windows user like me!

Now that the SIP Broker/open proxy thing was explained to me, I did manage to add in my dial plan a way to call out for free to toll-free numbers (Voxee charges it like a regular call and Teliax charges a connection fee) by adding this 1800xxxxxxx<:@proxy01.sipphone.com>S0 and all the other 866 variants to my dial plan so I can at least save money that way.
