Author Issue with Asterisk and BT ISDN 30 (Full ETSI)
Mark Simcock

2007-10-05, 7:11 am

Just recently BT have started installing ISDN 30 with a new standard that
drops the inital 0.

This creates a problem for us and the CLIP presented to the user can't be
dialed.

An example would be : -
1923123456

It does the same thing with international numbers but this time you get the
country code but no 00

I did find an example to add charators to the incoming cli but that won't
differentiate between national (which are missing 0 and international which
are missing 00)

How can this issue be worked arround and the number be presented in a
dialable format.

Thanks in advance,

Mark Simcock

How recent is this? A system I installed over a year ago did exactly this.

In zapata.conf:

nationalprefix=0
internationalprefix=00

[actually I set mine to 90 and 900 to make redial easier]

http://www.voip-info.org/wiki-Aster...fig+zapata.conf contains some
pointers, but you actually have to know the name of the parameter in order
to find the information on that page, which is annoying!

Thanks for that!

I've tried putting it in, it's not working but thats probally because I'm
missing some other perameters needed to get it to work. Can you either post
a working zapata.conf here or e-mail?

BT don't send the initial 0 on ISDN. They send a flag for national
number, or international number, or unknown number, followed by the
number. You have to replace that flag by a 0 or 00 as appropriate.
