<a href="tel:0044201111111">0044201111111</a>

For Skype this reportedly works:

<a href='callto:0044201111111'>0044201111111</a>

Support is not tested by me and seems to vary have varied,
but should be better now, according to:

<https://css-tricks.com/the-current-state-of-telephone-links/>

=============================

Now for Whatsapp I use something like this,
HRM being 91 years old now, please substitute another number:

var hrm = "https://api.whatsapp.com/send?phone=0044201111111&text=HRM";

<a onclick='window.open(hrm)'>Whatsapping to HRM</a>

This even works on my desktop, both the extension and the windows app.

The group posted to and the phrase "get to know" suggests that
bit-naughty is looking for client-side code to discover a number, not
have a number explicitly presented in HTML.  What number is explained by
the phrase "of that cellphone".  (I don't know the answer so all I can
do is clarify the question.)

Perhaps I was a bit naughty, 
but the response to that Q goes without saying,
as,
if clientside Javascript on a website 
was able to get such info about the user,
there would be no need for Edward Snowdon and Julian Assange,
as all would have been revealed already.

I don't think that follows at all.  First, the request might need
explicit position (as is the case for geolocation data) and second, how
could an interface that exposes a person's telephone number (no matter
how insecurely written) reveal all that Snowdon did or anything close
to it.

Yes, that's Exactly what I want.  Can a website running on the mobile browser of a phone get to know the PHONE NUMBER of that phone?

Right!

It should not, 
and by browser-design it probably is not, 
but how can you be certain?

Your phone might be compromized.

You may have been asked for your phone-number say 3 years earlier,
and a cookie of the same url still has the number.

[btw, websites run on servers, 
I trust you don't mean a website on a phone.]

Well, 
I don't necessarily agree,
my believe-system does not include believing in en.wikipedia.org,
and you could just have a severe attack of brexitis,
but if you think so, 
why not substitute another number,
for instance a Scottish one?

On what platform, and how careful were you when installing apps?

http://lifehacker.com/5991099/why-does-this-android-app-need-so-many-permissions
Every time you install an app in Android, you're presented with the
list of permissions the app requires in order to work. If you're not
reviewing that list before you click "Install," start now

For client side JavaScript, the mobile version of Firefox (not in other
browsers) has a feature called Web Telephony. Its API doesn't provide a mean
to retrieve the phone number(s) in the mobile device. It can only retrieve
the phone number of the incoming call.

For any applications however, they can retrieve the phone number(s) in the
mobile device. Depending on the mobile OS, some security level must be
granted to the applications first.

I don't recall that any mobile application that can access the local phone number.

The applications in this context are non web based applications. The phone
IMSI is provided by the mobile OS with security. IMSI is not exactly the
same as the phone number, but it does include the phone number except that
it includes provider-specific digits.

Can you give an example of a familiar mobile application that knows your phone number, without being explicitly told, simply by having permissions, and uses it?

The IMSI is a unique identifier of the user's SIM card. In today's GSM, 
UMTS and LTE networks, the IMSI does not contain the phone number 
(MSISDN) in general. A subscriber's phone number can change without 
changing the IMSI.
