Alex,
I had already tried it....reloading chan_dahdi.so module is enough...I
saw Asterisk was behaving differently after reload. To tell the truth,
setting pridialplan=unknown causes Asterisk to stop reading following
channels configuration...it says pridialplan is already unknown so it
stops evaluating chan_dahdi.conf file.... useless to say that all n+1
channels do not work. Maybe it is a bug but with that parameter set in
that way I cannot dial.
I'm sure Asterisk is dialling the right number:

3x 3x 3x 3x 34]
[2012-11-21 09:05:29] VERBOSE[8314] logger.c: > Called Number (len=13) [
Ext: 1 TON: National Number (2) NPI: ISDN/Telephony Numbering Plan

[2012-11-21 09:05:29] VERBOSE[8314] logger.c: q931.c:3134 q931_setup:

[2012-11-21 09:05:29] VERBOSE[8314] logger.c: -- Called 6/349xxxxxx4
I'm starting to think it is a telco problem... in case I'd change some
parameter like pridialplan or similar, shouldn't I just see a leading 0
in the frame like this:
[70 0b a1 *30* 33 34 39 3x 3x 3x 3x 3x 3x 34] added by Asterisk/DAHDI??
I've used this page as reference about frame fields:

Thank you.
