[Asterisk-Users] Q: PRI leading 0 (area access code) or 00 (country access code) missing on incoming callerid

[Frank Sautter]

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?!?

regards
  frank
