[asterisk-users] PRI Setup problem

[Alvin Austin]

I've recompiled with the latest svn sources for zaptel, libpri, and 
Asterisk.  Wanpipe is 3.3.0.p4.
Switched the T1 cable. Same result.

(It's a Sasktel Megalink T1/PRI circuit)

CLI> shows:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

D-channels available!  Using Primary channel 24 as D-channel anyway!
  == Primary D-Channel on span 1 up
  == Primary D-Channel on span 1 up

CLI> pri show spans
alternates between:
    PRI span 1/0: Provisioned, Down, Active   (most of the time)
and:
   PRI span 1/0: Provisioned, Up, Active    (during its retry sequence - 
below)

with debugging enabled:   CLI> pri debug span 1
