Hi,

Are there "provider independent" hard voip phones that plug directly
into a network router?

Or, are there "provider independent" "VoIP conversion boxes" through
which an ordinary telephone can be connected to a network router?

Thanks in advance for the info.

Cheers
Suranga

Of course, actually, most hard voip phones and gateways (a more proper
word for "voip conversion box" :) are provider independent, but most
providers ship them preconfigured.

Gateways I would recomend Cisco ATA 186, they work with major VoIP
protocols, if you want a SIP only version but cheaper you can also try
Linksys PAP2.

About hard voip phones I know only one but they worked fine, the Zultys
ones:

Most of them are, although many VoIP providers will pre-configure them to
your account if you buy from them. Saves a lot of hassle..!

As above.

Hi Martin, Ivor,

Thanks for the detailed explanations. I already have a spare phone, so
I will be opting to buy a "VoIP gateway".

Correct term is ATA (Analogue Telephone Adaptor) :-)

Well that's so relative, ATA is not very generalized, each company calls

it in a different way. For example Cisco calls them "ATA" (Analog
Telephone Adaptor) however Oki calls them BMG (Broadband Media Gateway)
and Vegasteam calls them VoIP Gateway (they're smart :). I still stick
with the "VoIP gateway" since by definition, a gateway translates from
one "coding" to another, in this case from analog audio to packets over
the wire... Yeah I know you will say "maybe you would have to say analog
audio-voip gateway" or something like that but I still like the word
Gateway :).

Isn't "FXO" the universal term?

Nope, FXO and FXS are types of VoIP gateways. FXO Gateways are the ones

who receive the phone line (so you can place calls from VoIP to POTS),
so they "receive the line current" (electrically, behaving as a phone,
kinda) and then you have FXS where you plug a normal phone to make
calls, they "provide the line current" (electrically, they behave as a
PBX/phone central). However not all VoIP gateways are either FXS or FXO,
since you have trunk VoIP gateways also (they have E1s/T1s and
interconnect with VoIP, though both systems are digital, their protocols
are different, well also the multiplexing and so on, Im not gonna go
into details :). Also you have things like GSM/VoIP gateways and so on.

Well, it provides an FXS interface but I wouldn't say that's a great term
for what it IS. An air conditioner provides cool air but it is not called a
"cool air". Or an air-temperature gateway, for that matter.

You can also get a box which combines the ATA with a router.
This is useful for somebody who has a single public IP address
from their cable/DSL provider. You plug one Ethernet to the outside
and the other Ethernet to your domestic LAN.

The box is a DHCP client to the ISP and a DHCP server to
your domestic PCs.

That would be the Sipura 2100.

Let's say you have an ATA which provides an FXS and an FXO port,
such as the Sipura 3000. Take a voltmeter and measure the voltage on
both ports. The FXS has some low voltage (dial tone) and the FXO
port has 0 volts.

If you happen to measure during a ring the voltage goes to some 60
volts.
