[asterisk-users] How to configure NT/ptmp with Dahdi and BRI ?

[Olivier]

Hi,

In my lab, I'm testing BRI spans in NT/ptmp mode.
My setup is:
asterisk 11.2.1
libpri 1.4.14
dahdi 2.6.1
wctdm24xxp (HA8 hybrid with B400M)

SIP phone <----> Asterisk with HA8 <----> Patton SN4638 <----> Asterisk
<----> SIP phone

The single BRI line I'm testing remains down:
CLI> pri show spans
PRI span 1/0: In Alarm, Up, Active

I'm quite certain this doesn't come from cabling as this setup worked OK in
TE/ptmp mode (ie Patton gateway acting as network and asterisk as terminal).

[  212.102644] wctdm24xxp 0000:0a:01.0: Found a Hybrid card: HA8-0000 (4
BRI spans, 0 analog channels)

As I was suspicious this came from the fact I previously used the same box
in TE/ptmp, I re-ran my installation script from the start but I'm still
getting the same result : the line is in Alarm.

Any hint ?
Did I miss something ?
