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: `--# tail -n 900 freeswitch.log| grep zap 2009-12-27 10:05:01.620610 [DEBUG] zap_config.c:56 Configuration file is /opt/freeswitch/conf/modules.conf. 2009-12-27 10:05:01.620738 [NOTICE] zap_io.c:2758 Modules configured: 1 2009-12-27 10:05:01.620765 [DEBUG] zap_config.c:56 Configuration file is /opt/freeswitch/conf/openzap.conf. 2009-12-27 10:05:01.620816 [DEBUG] zap_io.c:2362 found config for span 2009-12-27 10:05:01.621076 [INFO] zap_io.c:2579 Loading IO from /opt/freeswitch/mod/ozmod_zt.so [zt] 2009-12-27 10:05:01.621099 [DEBUG] zap_config.c:56 Configuration file is /opt/freeswitch/conf/zt.conf. 2009-12-27 10:05:01.640363 [INFO] zap_io.c:2379 auto-loaded 'zt' 2009-12-27 10:05:01.651465 [DEBUG] zap_io.c:2400 created span 1 (span1) of type zt 2009-12-27 10:05:01.651607 [DEBUG] zap_io.c:2413 span 1 [name]=[OpenZAP] 2009-12-27 10:05:01.651635 [DEBUG] zap_io.c:2413 span 1 [number]=[1] 2009-12-27 10:05:01.651652 [DEBUG] zap_io.c:2413 span 1 [fxo-channel]=[1] 2009-12-27 10:05:01.651667 [DEBUG] zap_io.c:2442 setting trunk type to 'FXO' start(KEWL) 2009-12-27 10:05:01.651847 [ERR] ozmod_zt.c:269 failure configuring device /dev/zap/channel chan 1 fd 42 (Function not implemented) 2009-12-27 10:05:01.651882 [DEBUG] zap_io.c:2362 found config for span 2009-12-27 10:05:01.651968 [DEBUG] zap_io.c:2400 created span 2 (span2) of type zt 2009-12-27 10:05:01.652022 [DEBUG] zap_io.c:2413 span 2 [name]=[OpenZAP] 2009-12-27 10:05:01.652041 [DEBUG] zap_io.c:2413 span 2 [number]=[2] 2009-12-27 10:05:01.652057 [DEBUG] zap_io.c:2413 span 2 [fxo-channel]=[2] 2009-12-27 10:05:01.652071 [DEBUG] zap_io.c:2442 setting trunk type to 'FXO' start(KEWL) 2009-12-27 10:05:01.652180 [ERR] ozmod_zt.c:269 failure configuring device /dev/zap/channel chan 2 fd 42 (Function not implemented) 2009-12-27 10:05:01.652207 [DEBUG] zap_io.c:2362 found config for span 2009-12-27 10:05:01.652282 [DEBUG] zap_io.c:2400 created span 3 (span3) of type zt 2009-12-27 10:05:01.652299 [DEBUG] zap_io.c:2413 span 3 [name]=[OpenZAP] 2009-12-27 10:05:01.652315 [DEBUG] zap_io.c:2413 span 3 [number]=[3] 2009-12-27 10:05:01.652344 [DEBUG] zap_io.c:2413 span 3 [fxo-channel]=[3] 2009-12-27 10:05:01.652358 [DEBUG] zap_io.c:2442 setting trunk type to 'FXO' start(KEWL) 2009-12-27 10:05:01.652483 [ERR] ozmod_zt.c:269 failure configuring device /dev/zap/channel chan 3 fd 42 (Function not implemented) 2009-12-27 10:05:01.652556 [INFO] zap_io.c:2502 Configured 0 channel(s) 2009-12-27 10:05:01.652573 [ERR] zap_io.c:2765 No modules configured! 2009-12-27 10:05:01.652589 [ERR] mod_openzap.c:2882 Error loading OpenZAP 2009-12-27 10:05:01.652605 [CRIT] switch_loadable_module.c:871 Error 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
