[asterisk-users] leading ghost 0

[gincantalupo]

Hi all,

I have problems dialling out because my new telco (the previous gave no 
problems) tells me my PBX adds a leading 0 and that's why I cannot dial 
out (but I can receive calls).

I make a small extensions.conf as a test:

exten => 666,1,Dial(DAHDI/g1/339xxxxxx)
but cannot dial out

Curious thing is that
exten => 666,1,Dial(DAHDI/g1/0233xxxxxx)
and
exten => 666,1,Dial(DAHDI/g1/233xxxxxx)
call the same number!!!

Line in use is a PRI.

My Asterisk version is 1.4.26.2
dahdi version: 2.2.0.2
wanpipe-3.4.6

I checked with intense pri debug and see no 0 inside frames....

How can I really be SURE Asterisk is not adding some leading zero?

Thank you.

Giorgio.
