Hello,

I am facing lot of voice cut after installing wctw235b card.

I am using libpri-1.4.14, dahdi-linux-complete-2.8.0.1+2.8.0,
asterisk-11.7.0.

I see error (http://pastebin.com/yJEgnnq7) on console.

Can anyone help me in this please.

Regards.

  • Well, Not to point out the obvious. But it’s complaining about the D-Channel not being in service.

    What’s the config look like on the other side? Is the D-Chan on some random channel? Or 24 and 48 as configured?

    For reference. This is what one of my PRI’s looks like.

  • It is 24 and 48. Kindly find the system.conf as below:
    # Span 1: WCTE2/0/1 “WCTE23X (PCI) Card 0 Span 1” (MASTER) ESF/B8ZS
    ClockSource span=1,1,0,esf,b8zs
    # termtype: te bchan=1-23
    dchan$
    echocanceller=mg2,1-23

    # Span 2: WCTE2/0/2 “WCTE23X (PCI) Card 0 Span 2” ESF/B8ZS
    span=2,2,0,esf,b8zs
    # termtype: te bchan%-47
    dchanH
    echocanceller=mg2,25-47

    # Global data

    loadzone = us defaultzone = us
    =========
    What could be the solution?

  • Sometimes you need to disable B-channel restarts, see chan_dahdi.conf.sample
