asterisk users - Mar 2009 - Is it possible to get full callin number from E1?

Hi all
    
    i have just set up a asterisk in china, using DE410P and one E1 line
    and get a phone number like: +86 020 87654321 from my sp
    when somebody dial  +86 020 87654321 , the asterisk will get the call in
number by ${EXTEN} variable, but it can only get 87654321, no area code .
    when someone dial  +86 020 87654321xxxx , xxxx means 4 digits,  the phone
can call in, and the  ${EXTEN}  is only  87654321 too ,
    is it possible to get  full call in number 87654321xxxx  in asterisk ? 
thanks

ssmax,

Use CALLERID(num) to get the number that was dialed.

On Asterisk side you can not configure what your telco will send you.

Enable pri debugging ("pri debug span 1" or "pri set debug on
span 1"
debpending on your Asterisk version).

Then call the number and watch the logging on the Asterisk console. you 
will see an incoming SETUP message. Take a look at the "Called Numer" 
Information Element. The called number is signaled as a number within a 
certain context (ToN=type of number). Probably the provider is sending 
you the called number with ToN=local or unknown, as you do not see the 
area code. Ask the provider to send you the called number with different 
ToN e.g. national and you should see the whole number.

CALLERID(num) is the calling number, not the called number

As others have mentioned in this thread, this is pretty normal... Telco's
all have different policies on how many digits they will pass for the
dialled number, some may let you specify, but often each telco has an
internal standard... You don't need the rest of the number, but if
you're
doing something where it would be useful to have it, you can easily add the
prefix yourself... It's also worth pointing out at this point, the prefix is
either 020 or +86-20 for Guangzhou depending on whether it's written for
national or international use, the 0 is not dialled internationally...

This is confusing... Guangzhou numbers are only 8 digits long + prefixes,
so, +86 20 87654321 would be the number... Where do you get 'xxxx' from?
What would be more normal would be that you'd by DDIs with your ISDN30
service, such that you'd have for example, a range of 100 numbers say from
87654000 to 87654099, though you can buy more... With this, the number
dialled (or the last 8 digits in your case) would be accessible through the
${EXTEN} variable... I guess it could be possible that your telco is
attempting to offer some other type of service that allows them to issue you
a single number, but, that they will accept as many as four additional
digits that they will pass to you in some way, but, it's impossible to say
what they are doing here and how it's been implemented... I would further
suspect that if this is the case that there would be a very distinct chance
that this would only work with inbound calls from other users of the same
telco, and in China, in the same city...

Within China, telco interoperability can be flaky at best and, from
experience, the fact the telco engineers don't entirely understand their
huawei switches for local problems and for problems over a wider area, the
fact that the national telcos are split into provincial and city
organisations that don't appear to communicate without going through some
circuitous route via the telco's head office both lead to some very long fix
times if there ever is a fix... That said, as long as you have cash, you can
get them to provide almost any service you want, though they won't often
offer anything but the most basic service, you have to ask for it...

thanks all
     i found the telco only send me the normal number 87654321 
     i just want to start a fax service and people can direct dial some extend
num like 87654321xxxx...but it never send to me ... so the only thing i can do
is to provide a ivr and let the people enter the extend num then jump to fax.
     thanks alot ~
