4 Port PRI

Hi Guys

I have a 4 port PRI card that I need to setup each port in their own group.

In chan_dahdi.conf I have the following which works for one port

How do I add the rest of the ports in their own groups so that I can have different signaling on each?

[channels]

language=en

switchtype=euroisdn

pridialplan=unknown

resetinterval`0

echocancel=yes

echotraining=yes

;echocancelwhenbridged=no

;rxgain=0

;txgain=0

callerid=asreceived

  • PRI or BRI? Which card are you using? Typically the installation script or procedure lets you configure each span. You seem to have 4 spans for either 8 or 128 (EuroISDN) channels.

  • When parsing the config file, all the current settings are applied when the
    ‘channel => ‘ directive is encountered. So something like this will make the three remaining groups and set signalling on ports 1 & 3 as pri_cpe and ports 2 & 4 as pri_net.

    ; setting specific to Group 2
    group=2
    signalling=pri_net channel =>

    ; settings specific to group 3
    group=3
    signalling=pri_cpe channel =>

    ; settings specific to group 4
    group=4
    signalling=pri_net channel =>

    BTW, this also means that the jitter buffer settings in your example are not in effect for the first group, but would be for the rest. All other settings would be the same for all ports.
