[asterisk-users] BRI D-channel goes up and down

[Vieri]

Hi,

I have a B410P card with span ports set up as
span=3,1,0,CCS,AMI
span=4,2,0,CCS,AMI
span=5,3,0,CCS,AMI

signalling = bri_cpe
switchtype = euroisdn
layer1_presence = ignore

However, I keep getting these messages over and over again:

[Dec 14 18:53:14] WARNING[22476]: sig_pri.c:1150 pri_find_dchan: Span 3: D-channel is down!
  == Primary D-Channel on span 3 up
  == Primary D-Channel on span 4 up
  == Primary D-Channel on span 5 down
[Dec 14 18:53:25] WARNING[22478]: sig_pri.c:1150 pri_find_dchan: Span 5: D-channel is down!

  == Primary D-Channel on span 3 up

It seems I can dial out and in but I'm afraid I may be losing some calls if they happen to dial in/out right when a span goes down.

libpri-1.4.13
dahdi-2.6.1
asterisk-11.0.1

Any suggestions?

Thanks,

Vieri
