1-15 and 17-31 are B-channels and 16 is the
D-channel; We
don't use E1s here in the
USA. I just finished
installing&nbsp; a PRI line, and being a complete novice at it myself, this
is what I wish someone had told
me: - the dahdi program
dahdi_genconf creates 2 files 1) /etc/dahdi/system.conf&nbsp; and 2)
/etc/asterisk/dahdi-channels.conf.&nbsp; The latter is the one that
maintains the configuration for asterisk.&nbsp; File chan_dahdi.conf is
where the configuration is maintain, you will need to have
an #insert
dahdi-channels.conf at the start of chan_dahdi.conf, otherwise it will never be
read. Else you can type the configuration yourselft in
chan_dahdi.conf -
Not written anywhere, but the way chan_dahdi.conf is read, there are no [XXXX]
separators, so any parameters in the file apply to the first "channel"
statement it finds. Hope
it
helps - Christian

Ask how numbers come through on incoming calls:  in "international"
format
(with IDD and STD codes, but without the leading double-zero and zero
respectively);  in "full national" format  (with STD code including
the
leading zero);  in "national" format with the STD code *but* with the
leading
0 stripped; or just the local number.

Also ask how they want you to send numbers on outgoing calls  (in particular,

do you need to insert the STD code even for a local call?)


Then, don't believe a word they say; and use something like
exten => s,1,NoOp(Call to ${EXTEN})
to see how they are _actually_ sending numbers to you.  Start out by sending

your numbers in the same format, but don't expect consistency.


Usually, channels 1-15 and 17-31 are B-channels and 16 is the D-channel; but

again, check this with the telco.  If your box can't find a D-channel, it
won't
work at all.
