Ring requested on unconfigured channel 255/255

After working fine for a week or so my new Quad E1 asterisk 1.8 system has started rejecting outbound calls from the Nortel
BMC 450 it is connected to.
The cli fills up with these:

sig_pri.c: Ring requested on unconfigured channel 255/255 span 3

Is this likely to be a
1) config error
2) cable issue (I made them)
3) hardware problem with the Digium card
4) software (lib pri)

Any clues? Anyone seen this recently (google shows it in 2005 but not since as far as I can see)

  • Tricky, by the time I’d got there, they had bypassed the Asterisk and plugged the BMC straight into the BT E1’s
    so all the channels will have been in red alarm.

    They did say that power-cycling the Asterisk machine cleared the problem for a while.

    The kernel log has some odd messages too:

  • If the call volume is low enough and the error reproducable enough,
    you may want to look at “pri set span 3 debug”.
