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

[liuxin]

Hi,

* [Jun 22 09:04:51] WARNING[30723]: chan_dahdi.c:2790 pri_find_dchan:
No D-channels available!  Using Primary channel 72 as D-channel
anyway!*

The error means that when it tried using the D channel 72 it was not
able to communicate. Probably a misconfiguration or you havent plugged
the cable in yet.
