[asterisk-users] Asterisk 1.8 - BRI D Channel going up and down every few seconds

[Marco Mooijekind]

Dear all,

I have the following challenge using Asterisk 1.8, using a Digium B410P
card on BRI (The Netherlands, KPN ISDN) .

DAHDI is running, dahdi_tools indicates OK on my span and light on back of
card is green.

However, in Asterisk i get the following warnings every few seconds:

[Jan  2 20:33:17]   == Primary D-Channel on span 1 up
[Jan  2 20:33:26]   == Primary D-Channel on span 1 down
[Jan  2 20:33:26] WARNING[1671]: sig_pri.c:1095 pri_find_dchan: Span 1:
D-channel is down!
[Jan  2 20:33:27]   == Primary D-Channel on span 1 up
[Jan  2 20:33:37]   == Primary D-Channel on span 1 down
[Jan  2 20:33:37] WARNING[1671]: sig_pri.c:1095 pri_find_dchan: Span 1:
D-channel is down!
[Jan  2 20:33:38]   == Primary D-Channel on span 1 up
[Jan  2 20:33:47]   == Primary D-Channel on span 1 down
[Jan  2 20:33:47] WARNING[1671]: sig_pri.c:1095 pri_find_dchan: Span 1:
D-channel is down!
[Jan  2 20:33:48]   == Primary D-Channel on span 1 up

Result is I cannot dial out or in into Asterisk.

The asterisk module states the D Channel is going up and down every few
seconds. Some googling on Asterisk, BRI, and this warning indicates that
there might be an issue with Aterisk 1.8.x and euro BRI, version of LibPRI
etc.
has anybody experienced these problems on BRI? Any suggestions with regards
to these warnings are welcome!

Kind regards,

Marco Mooijekind.
