asterisk users - Jan 2005 - Q: PRI leading 0 (area access code) or 00 (country access code) missing on incoming callerid

hi,

on our incoming E1-PRI from german telco Arcor the leading 0 for the 
(area access code in europe) and the 00 (country accescode in europe) 
are missing on incoming callerids.
only prepending a single 0 is not the solution as suggested by some 
writers on this list, because there is no way to differ between national 
and international callerids and it's not possible to make the decission 
based on the length of the presented callerid, as the length of the 
callerid can vary in most countries.

e.g.: i'm getting signalled 4123456789 which could be a call from 
"Barmstedt (Germany)" which has the areacode '4123' or from
Switzerland
which has the countrycode '41'

somehow our ericsson businessphone 250 fromerly connected to the same 
E1-PRI was capable of showing the correct number of leading 0s?!?

Hi,

standard asterisk doesnt support that. However it's in
bristuff (www.junghanns.net/asterisk) zapata.conf:

nationalprefix=0
internationalprefix=00

best regards

You should be able to determine the Type Of Numer / Numbering Plan through 
the CALLINGTON dialplan variable and then call SetCIDNum with the 
corrected digit string. However, there is a bug in chan_zap that prevents 
it from working. I still have not received the blessing from the legal
department for the Digium disclaimer. However, feel free to contact me 
directly if you want to test the patch.

BTW: The same applies to chan_capi.

after peter svensson gave me some hints on where to look after, i made a 
small patch to current cvs-head which should solve this problem, by 
returning the modified callernum.

the patch can be found on 
http://bugs.digium.com/bug_view_page.php?bug_id=0003493

the patch i made is now available through CVS-HEAD.

thanks again to peter svensson who gave me the relevant hints where to 
look after!

it is now possible to define prefixes in zapata.conf
internationalprefix=00
nationalprefix=0
localprefix=089
privateprefix=0891234
unknownprefix
is also made the channel restart interval per span configurable
resetinterval=86400
