[asterisk-users] Asterisk 1.8 - BRI D Channel going up and down every few seconds
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. -------------- next part -------------- An HTML attachment was scrubbed...

It should just request that the D-Channel be activated again and once the telco complies the endpoint can then continue with setting up a call. Last time I looked dahdi/libpri/asterisk did not handle this very well. Admittedly that was quite a while ago and I do not know the current status. The bugreport were this was discussed and still seems to be unresolved can be found at: https://issues.asterisk.org/jira/browse/ASTERISK-13176 Don't know if you have seen it but there's an B410P installation doc at: http://docs.digium.com/B410P/b410p-user-manual.pdf Since you bought a B410P you should be able to get support so just call Digium. Good luck. Look forward to hear how it goes so please update the list. Regards, Patrick
