SPA3000 and Asterisk -> Multiple Wireless Extensions –> Is this really possible?

Hi all.

I’ve been wading through tons of sites/ info on configuring up to 8-wireless extensions with Asterisk, yet there’s absolutely no mention of how this is accomplished. I’m running a Sipura SPA 3000 btw…  

So.. If I purchase a 5-phone Vtech system, then what? I guess my question is, how exactly do you setup multiple ‘private’ wireless extensions? How does the SPA and Asterisk identify their unique wireless handsets?

Or Maybe I have this all wrong. Perhaps the idea of buying 5 additional wireless extensions, is so 5-phones will ring simultaneously?  I’m not looking for a comprehensive explanation –just a basic idea of how the unique extensions are configured on each wireless handset.

I’m thinking you’d need to get the SPA 3000 to somehow acknowledge the additional wireless handsets.  Btw.. I’ve spent time on the Asterisk forums elsewhere, but… They are 90% questions and 10% answers, which is not terribly useful if you’re planning on doing anything beyond the likes of a pet project.   Hopefully, some good folks out hear can shine some light on this one.  

Ooops... I should be clear.  I'm speaking of the 5.8 Ghz analog handsets --not wireless IP phones.   Here's one example here:

Many thanks,

D.

The wireless phones you are looking at all share the single alanague tepephone line the base unit is connected to. Therefore if you but a unit which has 5 phones then all these 5 phones will ring at the same time and you can only make 1 call at a time. It is designed for houses or business premesis where the person answering could be in many locations and you dont want to have to carry the phone around.

If you wanted to have the additional phones each on separate lines and able to call each other and make outgoing calls independantly then you have 3 basic options :-

1) Buy separate wireless phones each having their own base unit. You will need additional SPA-2000 adapters to connect the extra analogue lines to asterisk.

2) As (1) above but instead of SPA-2000 you could get analogue interface cards for the asterisk box.

3) Install a wireless access point and use wireless VoIP handsets instead.

Grin…. Now I feel like an idiot.  

A certain blog makes numerous mentions of 5.8 Ghz phones with Asterisk, complete with their (up to 10 extension) capability.  Sifting through this blog again, it turns out their overlapping their suggestions/ instructions with ‘plugs’ for sponsored 5.8 Ghz products with multiple extensions.  Certainly understandable, but a trifle confusing when you’re simply trying to get an initial idea of how Asterisk works, in addition to its terminologies and capabilities.   Hey… That’s why I joined Experts Exchange :)

Anyway….  I’m using a Dell GX240 for the Asterisk server, so no available PCI slots ):  I don’t suppose there are any ‘standalone’ inexpensive FXO port boxes that allow you to plug in several Analog extensions.  I’m still running in a test environment, and just wanted to configure several independent extensions. Looks like the SPA-3000 is as good as its going to get as far as that goes.   It’d probably be easier to grab some low-end IP phones, and simply plug them into the router, right?

Many thanks grblades,

Dave

You will need FXS ports. FXO connects to an analogue telephone line while FXS connects to analogue phones. Sorry I dont know of any device like the SPA series which has more than 2 ports.

Yes the best way to test would be to get a few low end phones like the Grandstream Budgetone 101.
