Hi,

    
I have 6 Red FXO with TDM2400p in my PC. I have install asterisk and dahdi
driver.
Scenario is 

jitsi-----> asterisk server-----> analog PBX ----> landline phone

I configured this scenario as follow

in chan_dahdi.conf file

    ; General options
    [channels]
    usecallerid=yes
    hidecallerid=no
    callwaiting=yes
    threewaycalling=yes 
    transfer=yes
    echocancel=yes
    echocancelwhenbridged=yes
    rxgain=0.0 
    txgain=0.0
    ;FXO Modules
    group=2
    echocancel=yes
    signalling=fxs_ks
    context=Incoming
    channel=1-20



After loading module in astrisk giving o/p below

    module load chan_dahdi.so

After loading extension and dahdi, i called from jitsi and dialed 81 but
asterisk is giving o/p as below and  busy tone is coming on jitsi

    -- Executing [81 at myphones:1] Dial("SIP/sandeep-00000000",
"DAHDI/1,20,rt") in new stack

    == Spawn extension (myphones, 81, 2) exited non-zero on

Any help to resolve this problem.

The quickest way to get pointed in the right direction would be to 
contact Digium support since the issue involves your TDM2400P. Be sure 
you have the serial number of your card when you call (printed on the 
card itself, and included with the documentation you received upon 
purchase).

Please don't cross-post across the lists.

Thanks,
