[Freeswitch-users] freeswitch and dahdi give an error: device /dev/zap/channel chan 1 fd 42 (Function not implemented)

[jim cncrepair.com]

I am trying to get freeswitch to talk with a digium tdm400 card.  I am 
using ubuntu and the provided dahdi and freeswitch packages. 

I have configured /opt/freeswitch/conf/openzap.conf with the following:

`--# cat openzap.conf

     [span zt]
     name => OpenZAP
     number => 1
     fxo-channel => 1

     [span zt]
     name => OpenZAP
    number => 2
    fxo-channel => 2

     [span zt]
     name => OpenZAP
     number => 3
     fxo-channel => 3

dahdi's auto generated configuration is the following:

     `--# cat /etc/dahdi/system.conf

     # Span 2: WCTDM/4 "Wildcard TDM400P REV I Board 5"
     fxsks=1
     echocanceller=oslec,1
      fxsks=2
      echocanceller=oslec,2
      fxsks=3
      echocanceller=oslec,3
     # channel 4, WCTDM/4/3, no module.

     # Global data

     loadzone    = us
     defaultzone    = us

The Freeswitch log is the following:

Loading module /opt/freeswitch/mod/mod_openzap.so

To get to this point.  I had to symbolically link /dev/zap to /dev/dahdi 
and change the permissions of /dev/dahdi.  I gave /dev/dhadi 777 
permissions.


I hope someone can advise us what to do next.  Thank you
