Is it possible to connect two IP phones within the same premises in

The phones are a Linksys SPA-921 and a Siemens C460 IP if that has any

That depends upon the service provider.
Certainly with voip.co.uk you can have more than one device registered
& can make and receive calls on either device. Transferring calls
wouldn't work. Gradwell will also allow this.

I was able to have with my SIPGATE account multiple phones registered at the
same time,
not sure if this was a feature or because all phones had the same account
and same public IP address
I suspect the latter.
Even with a PBX system it depends on the service provider, some providers
VOIPBUSTER ETC only
allow one concurrent session for obvious reasons, where as other on a pay as
you go basis might give several
lines (at least for outgoing calls)
So if you want to be able to make 2 concurrent calls at the same time, you
can do it with an IP PBX with multiple accounts or multiline account
or
Use a a service provider which does the above function server side.
VOIPFONE offers hosted PBX features, but rather than pay a large monthly
charge for a virtual PBX you pay on a per feature basis for example an
extension is £0.99 / month

With Sipgate you can do the same, have the same phone number on both
devices and make and receive calls on both.

With Sipgate you can have the devices the other side of the world and
with the same account details in both, they will both ring when called.
You can both make calls at the same time too. If you dial your own
Sipgate number from the one device it will ring the other.

The account (single line) is with Gradwell.
Surely it can't be a case of just plugging them into the router and
letting it assign them suitable private addresses (currently
192.168.0.4) , or is it?
What I'm hoping to achieve is the Siemens cordless directly connected
to the broadband router (acting as a DHCP server) adjacent to the BT
inlet with the cordless also connected to the PSTN as an alternative.
Along with a wired non cordless phone this serves the main house usage
and gives me both BT and VoIP access.
The Linksys would be remotely located (circa 100m away) adjacent to a
PC already connected to a wireless print server (Netgear WGPS606)
The wireless network is up and running and both phones work ok when
connected individually at the PC end.
This saves me running any cabling (which would be particularly
difficult hence me using a wireless network)

That's interesting.
I can't ring from one Sipgate account to another if they're both on the
same IP, let alone two with same credentials.....though I've never
tried the latter.

Yes.
As far as I'm aware, though, Gradwell charge a little extra for
multi-line services - I could be wrong.....

I just tried it and can confirm it works (using 2 ports on my DrayTek
2800VG), although I didn't do it from the other side of the world!

Yeah, it works.
Also you can transfer the call (or have 3-way call) with your other line
simply again by dialing your own number.

It depends on what you want, they allow you to have 2 incoming calls per
number and an unlimited number of outgoing calls.

You could use a Virtual PBX such as Axon from NCH Swift Sound which
will handle multiple VOIP extensions (USB, WiFi or softphones) on a
network and also multiple VOIP service providers. It will ring all the
extensions for an incoming call if required.

It's called call forking and is a standard SIP feature. It *should* work
with any provider, although I suppose it's possible that some have found
ways to disable it.

It depends on what equipment you're using. I had terrible problems with a
Sipura SPA-2000 and a Netgear 602 modem/router with 2 Sipgate accounts,
sometimes it would work from one line to the other, sometimes not. It was
eventually sorted when I replaced the Netgear with a Fritz!Box. The Sipura
works fine plugged into the Fritz as well.
I can even take my SPA-1001 to Germany and the USA and it works fine with
2 of my Sipgate numbers in it as well.
I suspect things like this are part of the reason that Sipgate amongst
others gets a bad press, it's the user's equipment and not Sipgate a lot
of the time (I won't say *all* the time just in case Dexter is about..!!)

I never thought it was a Sipgate fault as the accounts were fine on
different networks - I presumed it was some issue internal to my
network

Could well be some of the reason, but I have to say that I have multiple
providers configured on my FritzBox, and I have call quality and DTMF
recognition issues on Sipgate calls where I don't with others. They may be
good as a cheap and cheerful second line, but I would not be able to use
them with my setup as a PSTN replacement.

Hmm. I have a number of Sipgate trunks, none of which have any
difficulty whatsoever with DTMF.......you're new to the Fritz!box,
aren't you?

Strange, I have two Sipgate UK accounts, one Sipgate DE account, a FWD
account, one Gradwell account and a private direct link to a friend's
Asterisk box on my Fritz!Box and all work fine with no discernable
difference in call quality on any of them.

I've had the FritzBox for a few months now but I had the same issue on my
previous ATA. In any case, the call quality generally is nowhere near as
good as my other providers. There is clearly something about Sipgate that
makes it prone to quality issues.
Although there may be a way of solving them, I haven't found it yet.
However, I suspect it is something to do with internet routing somewhere,
which is a problem that cannot be solved by users. I suspect there are one
or more weak points in the potential routes to Sipgate servers which clearly
cause some users issues while they don't for others.

I have 3 Sipgate accounts, a voip.co.uk and voipcheap com account among
several others which are used less frequently. I have quality problems with
all the Sipgate accounts and additionally a voxalot account, although I have
not tried this since they migrated the servers to the EU.
I have a more than adequate nominal bandwidth (400k upstream, 4mb down) and
all the speed tests I have done have been well above 100k in both
directions, except when I had a performance issue with my computer (wouldn't
affect the ATA in any case). A voip quality test also resulted in good
ratings. Switching codec selection around on the Fritz made it worse, but I
have never had these issues with vc or voip.co.uk in any case, and they are
well used..
I have got to the limit of what I can do to improve things, nor do I have
the will when I have other services working perfectly well. Perhaps you can
now understand why I don't recommend Sipgate as a PSTN replacement, although
it works OK if you can accept the quality constraints. I am of course only
one user, but in view of the quantity of other complaints, it would appear I
am not alone. I also don't see the financial benefits for calls to PSTN
when there are better quality providers that work out to the same costs for
me. Inbound is obviously free but the quality is unacceptable to me for a
primary phone line, when you can make a one-off topup of £10 for an inbound
number with a good quality line from voip.co.uk.
Sorry to the OP for hijacking the thread, but I say as I find.

If you take into account the total Sipgate customer base, the few
complaints you see here are hardly representative.

Same here, and there *are* no quality constraints here.
