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 ~

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 .
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...
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
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...
