Hi,

I’m experiencing difficulties to get a B410P running with Asterisk
10.3.1 and DAHDI 2.6.1.
Am I supposed to use DAHDI for this card and ISDN BRI for my country
(Belgium)?

thx,

BC

  • That is the supported method to use in standard Asterisk, yes. DAHDI,
    libpri and Asterisk working together.

  • Hi Bart,
    here is a working configuration in Netherlands:
    /etc/dahdi/system.conf:

    span = 1,1,0,ccs,ami
    bchan = 1,2
    hardhdlc = 3

    span = 2,1,0,ccs,ami
    bchan = 4,5
    hardhdlc = 6

    span = 3,1,0,ccs,ami
    bchan = 7,8
    hardhdlc = 9

    span = 4,1,0,ccs,ami
    bchan = 10,11
    hardhdlc = 12

    loadzone = nl
    defaultzone = nl (of course change those to your country initials)

    /etc/asterisk/chan_dahdi.conf:

    group = 1
    signalling = bri_cpe_ptmp
    switchtype = euroisdn
    context = mainmenu
    echocancel = yes
    channel => 1,2,4,5,7,8,10,11

    I am not using dahdi-channels, hope it helps!

  • Hi Khalid,

    my setup is almost identical

    except for
    loadzone = be
    defaultzone = be

    (obviously)

    and in

    chan_dahdi.conf:

    [isdn4]
    signaling = bri_cpe_ptmp
    switchtype = euroisdn
    group = 2
    context = isdn
    dahdichan = 10,11

    this results into:

    ERROR[1021]: chan_dahdi.c:14182 dahdi_pri_error: PRI Span: 4 Unable to
    receive TEI from network in state 2(Assign awaiting TEI)!

    and after trying to call:

    May 9 21:25:51] NOTICE[1021]: chan_dahdi.c:3136
    my_handle_dchan_exception: PRI got event: Alarm (4) on D-channel of span 4

    An old Asterisk 1.4 installation with mISDN connected to the same line
    used ptp, not ptmp. When I used bri_cpe_ptp, I get even more problems on
    the console however (every second).

    This is why I wondered if DAHDI is supposed to work over here,

    cheers,

  • bri_cpe_ptp is not a valid value for the signaling parameter.

    From chan_dahdi.conf.sample:
    ; bri_cpe: BRI PTP signalling, CPE side
    ; bri_net: BRI PTP signalling, Network side
    ; bri_cpe_ptmp: BRI PTMP signalling, CPE side
    ; bri_net_ptmp: BRI PTMP signalling, Network side

  • Right you are,

    but when using bri_cpe I get:

    [May 9 23:08:45] WARNING[2775]: sig_pri.c:6969 pri_dchannel: PRI Error
    on span 4: Received MDL/TEI managemement message, but configured for
    mode other than PTMP!

    This repeats itself every second.

    The

    bri_cpe_ptmp

    settings seems to give the least troubles, but no calling possible,

  • oops, that was my intention, my bad.

    I just tested: yes it seams so!

    Will do. I suppose there is no way to make them disappear already,
    except for turning of WARNING messages.
