I have an SPA-3000 set up with a DECT base-station in the FXS port and
configured for a Sipgate account. Trouble is although there are two DECT
handsets I can never actually make or receive telephone calls because both
handsets are always randomly hidden around the house - usually under a pile
of teenage junk in kids bedrooms.
Is there any way I can add two extra lines for kids exclusive use so they
leave mine alone? I have a strong feeling that if it can be done at all then
the answer is going to involve Asterisk; would be prepared to do this with
an old PC but just so long as I don't have to spend out on special voice
boards or anything. I don't really understand how Asterisk works or how it
would interface with the SPA.

I think that there are basically 3 answers to your problem.
1. 'Asterisk at home' software - loads very easily in one go and will
work on an oldish machine. Installation will probably take about half
an hour as it whirs away on its own - no need for intervention.
2. Get another ATA - you can use more than one - it's just another IP.
3. Get some SIP phones - again just more IPs to add to the system.
I think option 3 is out on cost grounds and other possible port
forwarding problems.
Option 1 affords the maximum flexibility but requires some learning.
Option 2 is possible - you might find something on ebay.
The only problem I can foresee with option 2 is port forwarding as you
already have one ATA..
You would probably be best with an ATA which went before the router in
this case - someone else here with more experience might be able to
advise on that one.
As regards Asterisk: The ATA connects to the system as it does now but
the computer links to it via its IP on the internal network. With
'Asterisk at home' you will be able to control the old computer ( you
Asterisk box) via a web interface on your usual computer - so no need
for a monitor etc. on your old computer once it has been set up.
If you are prepared to spend a little time learning how to operate
'Asterisk at Home' then this would be the best option.
The only disadvantage is the cost of electriciy so you need to choose
a computer that isn't too power hungry and possibly put it on a timer
so it switches off whilst the kids are in bed.

An additional ATA would probably be the easiest option. I have 4 Sipgate
numbers and one FWD number here..!
Note though that it is sometimes difficult to get two ATA's working behind
one router, but it can usually be done.

I use a netgear router and have never had to forward ports to make or
recieve calls using sipgate using either a ATA or SoftPhone thats the idea
of the stun address "stun.sipgate.net:10000"

At that point, it's usually less bother to get an Asterisk box with
two (virtual) network interfaces on the job.
Less bother to get a SIP aware modem/router maybe, but Asterisk is a
bit of a mouthful for most people to chew on - after all, we didn't
need telephone exchanges in our houses before so why should we need
Asterisk now ?

You didn't have N lines then either (where N >2 for example). And if you
did, you didn't get away with paying for one and piggy-backing the
others at (possibly) no charge and allowing multiple simultaneous calls.

One can also install Asterisk on some routers eg Linksys WRT54G, but I
suspect these are rather low-horsepower systems, and you couldn't run a
call centre on it for example.

Thanks for suggestions. I have to say I'm kind of peeved with the SPA-3000 -
it's infinitely configureable thus hard work to understand and yet every
time I want it to do something objectively useful (extra lines, least cost
routing, resilient routing) it turns out that the box can't directly support
it.
I'm especially cross that the SPA-2000 does in fact have two FXS so my extra
line problem could have been solved easily if I'd bought the earlier model.

Take cheap PC, wave Debian over it, aptitude install asterisk, edit
sip.conf and extensions.conf, and you're done.

Before now, we had one phone, provided by the GPO, in a choice of any
colour as long as it was brown, and it was screwed to the wall.

I'm using a (german) Fritz!Fon Box WLAN:
all-in-one: modem, router, VOIP, wireless lan
with 3 analoge ports, and 1 ISDN port (where you can connect up to 8 ISDN
devices)
I have 8 VOIP accounts registered, all working
no issues with port forwarding ...

Different, not necessarily earlier.
The 2k cannot connect directly to PSTN, the 3k can.

I do. Asterisk is highly versatile and hence highly complex. It is far
from trivial to setup and configure and needs a PC running 24/7.
If you need multiple lines, multiple extensions, voicemail, call
forwarding etc its the ideal solution.
In other words if your requirements would have dictated an analogue
switchboard then an Asterisk/VoIP solution would be equivalent or
better.
For most domestic users an ATA seems to be sufficiently offputting so
I think Asterisk is out of the question for them. An ATA that provides
a coupler of incoming providers and up to 4 outgoing providers should
cover most requirements for domestic use.

that was before 20 years ago, no need to get carried away. I'm talking
about what someone did last week with analogue compared to something
similar next week with VoIP.

Is it just me or is the ability to connect to PSTN completely useless for
the domestic user?
For me the whole point of having VOIP is so I can get rid of PSTN line and
stop paying its expensive line rental and call charges.

Useless to you perhaps, but not everyone.

That's a valid point, but again it doesn't apply to everyone.
My AVM Fritz!Box has the ability to act as a call forwarding device, if
you call in on the PSTN line it can dial out on the VoIP line, or vice
versa. This is useful for a lot of people. I believe the Sipura 3000 has a
similar facility.

its just you.
70% of UK broadband is ADSL over a PSTN line, so the line is there
anyway and can continue to receive incoming or be used for outgoing
if/when its cheaper than the VoIP or the VoIP / ADSL goes titsup.
So integrating VoIP and PSTN onto one phone or set of phones seems
very sensible to me, especially as it can be made invisible to
technophobic users.
The case is less strong if you have non-ADSL broadband.

Not just him, but a lot of people think this way.

Indeed. Which is why the devices that do connect to PSTN usually have a
fallback option to PSTN if the power fails.

Agreed. I have 4 Sipgate lines into my PABX, where they appear alongside
the PSTN as just more exchange lines. The system can route calls over the
most appropriate route, or you can select a particular line if you want
to.
> The case is less strong if you have non-ADSL broadband.
For domestic users, yes. For businesses, or those of us who are just plain
telephone nuts, less so..!

For my part I agree. I ditched my BT line and took a TW broadband
connection with no landline in order to save on the line rental.
Having said that with 8M speeds in the offing via LLU, and some LLU
going at £9.99/month, it may soon be just as cheap to be on BT and
have a fast broadband connection.
I have an SPA-3000 but don't use the PSTN connection. However, I am
thinking of using that to connect to a door phone - a 50V d.c. supply,
a IK resistor and a cannibalised phone should be all I will need I
think.
How to get extra lines with SPA-3000?
