How does it know its VOIP - or does it

| Dave Saville 2007-09-03, 1:11 pm |
| If I dial the PSTN number assigned to a VOIP phone from another VOIP
phone does it know it is IP to IP or would it treat it as a land line
call? Or do you need to set up the call differently?

In most cases, the call will get treated like a landline call. Into
your SIP service provider and back out again.
To me, it doesn't really matter how the call gets there. Whether you
get charged for the call, is a different matter.
Within the same SIP service provider, it is dependant on their policy.
For example, if you dial 01484 840048 from Gradwell you won't get
charged. Gradwell don't charge for internal calls.
There is a system called enum, which isn't officially active in the UK.
This allows you to lookup the SIP address of a phone number, therefore
always routing the call over SIP. Until various people pull their
fingers out for the official service, then you can use enum by
registering on e164.org

You usually have to dial a prefix code. For example from Sipgate to
Gradwell you dial 000393 then the Gradwell SIP number. The other way
around is a little more complex, you dial **777 then the full PSTN number
in international form but dropping the 00 i.e. **777442070431320 (that's
the number of my speaking clock, feel free to try it..!)

That's another alternative but I've never managed to get it to work
properly, maybe it's me.
Don't forget also that some VoIP providers block access to SIP calls from
other providers.

What does a SIP address look like? I've got a couple of SIP 6-digit 'user
names' allocated by voip.co.uk - but I assume that they are specific to that
supplier, and not unique in the world?
They seem to be linked to my SIP phone numbers with a string: {SIP#}@{My WAN
IP address}:{Port#}
Is some/all of that my external SIP address?

I know that Nominet have tendered to run the enum service.]
In the mean time, e164.org works fine.

I thought they were losing the fight. Wasn't there a closed beta test
where nominet got a number range and so did 2 other companies (finished
in 2004 iirc). I think the whole thing is silly, it's as if there's an
obsession with the need to have as many people trying to make money from
it as possible.

Interesting ... I've just tried a lookup with dig, if +44 116 is a
non-existand domain, does that just mean nobody in Leicester has
registered a number with E164.org?

Is registration normally done by the number block owner (i.e VOIP
gateway owner) or by the individual number owner, in which case how do
you establish "ownership" of the relevant zone underneath
6.1.1.4.4.e164.org?

You'd need to know it was a SIP address, if you want it to be obvious in
either case you'd use prefixes like
mailto:tim@provu.com
or
sip:tim@provu.com
not everything with an @ in it is an email address :-)

OK, to answer my own question, I see you can register individual phone
numbers, the registration process gives you a PIN on screen, then places
a phone call to the PSTN number you provide, you answer and then respond
with the PIN via DTMF, I'll have to play ...

Nothing really.
Well only that a SIP client will talk to a SIP server and an email
client will talk to an email server.
In the network they are treated completely differently.

You need to lookup a full number.

By individual numbers I believe.

Well that wasn't too hard, the process was the opposite way round to
what I though, you give it your phone number and a SIP address, it makes
a test SIP call to verify it exists, then it makes a phone call to the
PSTN number and dictates a PIN to you and you enter the PIN into the
website to verify (not the other way via DTMF as I though)
I'm surprised it doesn't have some form of PIN verfication on the SIP
part as well as the PSTN part.

What do you mean with you never managed to get it work properly ??
* Are you not managing to get your phone numbers registered to e164.org ?
* Or are you not managing to call a ENUM registered phone number with your
VOIP equipment ?
* Or are you not manging to receive calls via your registeerd sip adress
The first one is very simple: see Andy Burns reply further in this tread how
to register
The second one is also simple: I assume you still use your FritzBox
If "ENUM" is enabled in your FritzBox, then the Box will first check at
e164.org wether the phone number you dialed has been registered.
In this case, the call goes directly to your SIP adress.
To receive "ENUM" calls with your FritzBox, you may want to reserve 1 of
your 10 Sip entries just for this purpose.
Give this entry any number (1234)
you then can receive calls at sip:1234@ivorjones.dyndns.org (example)
Of course, you will need to have your IP adress registered to a dyndns or
similar. The FritzBox can manage the updates to the service

OK, I've registered at e164.org and I've added one of my voip numbers
(supplied by voip.co.uk) and have had the call-back and entered the supplied
PIN.
What next? What does that enable me to do - or enable anyone else to do with
my number, for that matter? [Their White Pages looks a bit sparse - only
finding 1 Smith, 3 Browns and no Joneses in the whole of the UK! - am I
missing something?]

It means if anybody with e164.org on their phone system dials your phone
number, then the call will be placed over SIP and avoid the PSTN.

Thanks. Could you explain a bit further please? Just what does having
"e164.org on their phone system" mean? My 'system' consists of a Linksys
PAP2T connected to my ADSL router, with both its phone ports registered to
voip.co.uk Can I put e164.org on *my* system and, if so, how?
Also, I'm under the impression that voip.co.uk don't knowingly permit voip
to voip calls to and from other companies' customers, and that voip to voip
calls between their own customers can only officially be made by dialling
the geographic number. Does the use of e164.org circumvent that in some way?
Sorry if these questions are naive, but I'm still trying to get my head
around just what e164.org is and does.

Even though voip.co.uk don't allow SIP calls from off-net?
