[asterisk-users] PRI span problem - no D channel

[Mike]

Hi,

 

I have the following happen to me after the restart of one of my servers:
out of my 3 PRIs (all configured with the same technical settings), the last
one isn't coming back.  It's underutilized (chances it didn't get a call
since my reboot), if it makes a difference .

 

The PRI goes from provisioned to unprovisioned, and I get this regularly:

[Jun 22 09:03:48] WARNING[30723]: chan_dahdi.c:2790 pri_find_dchan: No
D-channels available!  Using Primary channel 72 as D-channel anyway!

 

Here is my PRI debug span:
