Hello,

I just bought the following set up:

SPA9000
SPA-400

I bought a Linksys SPA series phone and a Grandstream phone to test as generic SIP with the system. I understand you can assign extention and user information to a generic sip under "Line 1, Line 2 Line 3, and Line 4" on the SPA9000 tab but arent those also the area where you would put in user authenication information for ITSP? Is there a definite area where I can manage phone extentions and registrations?

Is there any limition using a generic SIP phone versus using a SPA series phone besides the ease of set up?

Another question is, the SPA-400 has 4 FXO, if i plug in 4 analog lines will that take up the 4 availiable Line account on the SPA9000 or do i still have 3 other lines for ITSP?

Thanks!

1) The SPA400 will always use one line.. see the admin guide for more info or search for the 2 threads on the SPA400 for precise details (coming from a guy without the device.. makes you think doesn't it
2) You are correct about the authentication information.. Line1-4 are the tabs where you can configure up to 4 IPTSP lines including authentication. If you need VIA or STUN, those can be configured in the SIP tab. You are mistaken about the user configuration.. there's simply no such thing on the SPA9000 (see further down)
3) As far as the phones go, the SPA9000 mostly supports the standard SIP RFC with some extensions, so if the other party does, too, then you should be okay. But not every phone really interoperates all the way and don't expect that add-on features like calling a shared line = all phones that have it rings will not work with a standard SIP phone as this is a protocol extension (a standard SIP device is supposed to pick one device, then make a call to it.. the SPA phones make simultaneous calls to all phones having the shared line). But I've been unable to connect certain softphones and somebody has reported a problem with another ATA. But those may or may not have something to do that with the little amount of configuration needed for the SPA9000, you can't register any device with an IPTSP, so if a device insists on a password or some form of authentication, you're SOL (though I don't see the RFC requiring anything like that).

As far as extensions goes, that one can indeed be confusing. Unlike a traditional PBX, you don't configure extensions on the SPA9000. All you need to do is put the SPA9000's IP and port (6060) as the proxy address on the phone, then use any user id (= number) you like, and no password. It should be possible to require a password on the SPA9000 but I've never tried that.. I think it would have to be set under "Phone Ext Password" at the bottom of the SIP tab.. and as you can see there's one password for the system.

Alann, regarding your last question about analog lines vs. SPA9000 lines, that is confusing. It turns out that an SPA9000 "Line" is really a particular source ("trunk") of lines.

Originally that meant one ITSP per SPA9000 "Line", but each ITSP could handle multiple inbound/outbound calls on that Line.

An SPA400 acts as (or in place of) one ITSP for the SPA9000. That means that the four analog lines coming in to the SPA400 are handled by _one_ Line tab on the SPA9000, leaving three additional Line tabs open for additional providers (either ITSPs or even additional SPA400s).
