This dAHDI stuff is like voodoo! I know this has to be configuration issues but sh****t after a few years in the telecom industry it is really hard to find a more awful syntax for configuring such a stupid device as an FXO port. I am trying to get a Xorcom Astribank going with FreeTDM. So far after a bunch of firmware and driver BS (come on there is probably nothing more buggy in a freking kernel than the USB layer, how can a telecom device be using a USB driver!!!!!!!). I get the following output from #lsdahdi ### Span 1: XBUS-00/XPD-00 "Xorcom XPD #00/00: FXO" (MASTER) 1 FXO RED 2 FXO RED 3 FXO RED 4 FXO RED 5 FXO RED 6 FXO RED 7 FXO RED 8 FXO RED ### Span 2: XBUS-00/XPD-10 "Xorcom XPD #00/10: FXO" 9 FXO RED 10 FXO RED 11 FXO RED 12 FXO RED 13 FXO RED 14 FXO RED 15 FXO RED 16 FXO (battery) ### Span 3: XBUS-00/XPD-20 "Xorcom XPD #00/20: FXO" 17 FXO RED 18 FXO (battery) 19 FXO (battery) 20 FXO (battery) 21 FXO (battery) 22 FXO (battery) 23 FXO (battery) 24 FXO (battery) But when loading mod_freetdm I am getting: 2011-09-19 15:44:03.149105 [NOTICE] ftdm_io.c:5723 Modules configured: 1 2011-09-19 15:44:03.149105 [DEBUG] ftdm_config.c:80 Configuration file is /usr/local/freeswitch/conf/freetdm.conf. 2011-09-19 15:44:03.149105 [DEBUG] ftdm_io.c:4633 Reading FreeTDM configuration file 2011-09-19 15:44:03.149105 [DEBUG] ftdm_io.c:4649 found config for span 2011-09-19 15:44:03.149105 [NOTICE] ftmod_zt.c:1323 Using DAHDI control device 2011-09-19 15:44:03.149105 [INFO] ftdm_io.c:4963 Loading IO from /usr/local/freeswitch/mod/ftmod_zt.so [zt] 2011-09-19 15:44:03.149105 [DEBUG] ftdm_config.c:80 Configuration file is /usr/local/freeswitch/conf/zt.conf. 2011-09-19 15:44:03.149105 [INFO] ftmod_zt.c:585 Setting rxgain val to 0.000000 2011-09-19 15:44:03.149105 [INFO] ftmod_zt.c:593 Setting txgain val to 0.000000 2011-09-19 15:44:03.149105 [INFO] ftdm_io.c:787 Auto-loaded I/O module 'zt' 2011-09-19 15:44:03.149105 [DEBUG] ftdm_io.c:4670 created span 1 (SPAN1) of type zt 2011-09-19 15:44:03.149105 [DEBUG] ftdm_io.c:4688 span 1 [fxo-channel]=[17-24] 2011-09-19 15:44:03.149105 [DEBUG] ftdm_io.c:4718 setting trunk type to 'FXO' start(KEWL) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 17 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 18 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 19 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 20 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 21 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 22 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 23 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftmod_zt.c:288 failure configuring device /dev/dahdi/channel chan 24 fd 48 (No such device or address) 2011-09-19 15:44:03.149105 [ERR] ftdm_io.c:4579 1:Failed to configure span 2011-09-19 15:44:03.149105 [INFO] ftdm_io.c:4885 Configured 0 channel(s) 2011-09-19 15:44:03.149105 [ERR] ftdm_io.c:5733 FreeTDM global configuration failed! 2011-09-19 15:44:03.149105 [ERR] mod_freetdm.c:4805 Error configuring FreeTDM 2011-09-19 15:44:03.149105 [INFO] switch_time.c:1028 Timezone reloaded 530 definitions 2011-09-19 15:44:03.149105 [CRIT] switch_loadable_module.c:1019 Error Loading module /usr/local/freeswitch/mod/mod_freetdm.so **Module load routine returned an error** 2011-09-19 15:44:03.149105 [NOTICE] ftdm_sched.c:147 Main scheduling thread going out ...
