asterisk users - Nov 2006 - Setting the CallerID

Hi,

I have some trouble with setting my CallerID if i make an international
Call. No Problems with National Calls, i can set whatever I want. We pay
for this service but our telephone provider was not able to state clear,
wether the number we set on an international call should be shown on the
other side.

Actually only our base number shows up.

If I understand it correctly, in every call the base number is embedded
as ANI, so that we can be billed.

Is it possible, that, if a calls goes international, they only refer to
the ANI and forget the set number ?

The only route I am trying is from Germany to England, maybe it is a
problem between the providers and not of my setup.

Maybe someone could explain to me how CallerID transmission is done on
the technical level I could guess where i have to look for an solution.

Thx.

With that, do you mean the number without international prefix? That's
odd.
What's the provider you are calling here in uk?
I regular get calls from Germany with the correct international callerid
showing.

I don't receive any callerid from some (cheaper) german telco providers
(but most work correctly)
I vaguely remember that there are some pretty dodgy contractual
agreements lingering around. You might want to google for 'europe
callerid', specificially [1].
Are you sure your calls goes straight from Germany to UK? I found that
many German telecom providers terminate through the US, particularly to
landlines.

Maybe you could route your call to via sip to a uk voip provider and
persuade them to set the callerid to whatever you have in Germany? or
simply get a UK number routed via sip ? ;)
