Re: How to do an SPA-3000 setup like mine...
said by kreil  :Regarding using the "line" of the SPA3000 - isn't this a POTS FXO port to go to the phone company? Yes.
The Sipura manual describes the "Line" port as what you hook up a real telco/POTS "phone line" to (if you wish to use the telco/POTS interconnect features of the device). And that is in fact a useful thing to do with the "Line" port. But it is not the only possible use of the "Line" port.
Here are some other uses clever people over on the Voxilla.com forums have also made of the "Line" port:
1) Since the "Line" port is expecting a telco "phone line", anything that mimics a real phone line will also work. So you can plug the "Phone" port of some other adapter, into the "Line" port of the SPA-3000. This works, because the "Phone" side of pretty much any VoIP adapter is pretending to be a "phone line" to the "phone" they expect you to plug into the device. Since the SPA-3000 "line" port is designed to work with a real "phone line", and the ATA you are plugging it into is pretending (to the "phone" it thinks it's hooked up to) to be a telco line, both adapters are "happy". This allows you to combine VoIP features of an SPA-3000, with features from another "locked" VoIP adapter (on the same "phone").
2) One especially clever user (no it was not me) over on Voxilla.com, figured out that it is actually OK to connect the SPA-3000's "Line jack" (that expects to be hooked up to a phone line, and mimics a phone) and "Phone jack" (that expects to be connected to a "phone", and mimics a "phone line") together. You might wonder why you would ever do such a "silly" thing. The reason is, that it allows you to call into your SPA-3000 via the PSTN side "VoIP provider", authenticate (PIN access) with the adapter, to let you call out via the "telco line". But in this case, since you have hooked the two jacks together (possibly via a telco "Y" cable, so you can also hook up a real "phone"), the "Phone" side of the SPA-3000 thinks that you have just picked up the phone in the house (as soon as the "Line" side of the SPA-3000 takes the "telco line" off hook)! The practical upshot of this, is that you can call into your SPA-3000 by VoIP, and then out again making that call "as if" you were making it directly from the SPA-3000. Round about way of doing things, but very clever IMHO.
3) And if you ever later setup an * server, you can redirect your SPA-3000 to the * box (instead of having the SPA-3000 do VoIP directly with the outside world). If you do this, you essentially get one FXS port (the "Phone" jack of the SPA-3000) and one FXO port (the "Line" jack of the SPA-3000) that can be remotely controlled by your * server. Again, I haven't done this myself yet (mostly because I haven't yet setup an * box). But it is nice to know that my investment in Sipura adapters will _NOT_ be "wasted" if/when I do go to *, as I can just recycle the adapters as FXS/FXO interfaces for *! |
