Trying to get this working on FreeBSD 5.4. zaptel-0.10_1 driver from ports. Digium TDM400 ( don't remember all these codes, but the card has fxs module in the 1st socket, and fxo module in the 4th one. /usr/local/etc/zaptel.conf loadzone=us defaultzone=us fxsks=4 fxoks=1 When I start the system, both modules get detected but I get "TDM PCI Master abort" message, which goes away if I run /usr/local/etc/rc.d/zaptel.sh stop, unloading the modules. Running this again with start argument, loads the modules without the above mentioned message, also detecting both modules, but ztcfg shows "ZT_CHANCONFIG failed on channel 1: Device not configured (6)" output of ztcfg -vv Zaptel Configuration ===================== Channel map: Channel 01: FXO Kewlstart (Default) (Slaves: 01) Channel 04: FXS Kewlstart (Default) (Slaves: 04) 2 channels configured. ZT_CHANCONFIG failed on channel 1: Device not configured (6) what would be the basic troubleshooting steps ? thanx a lot in advance.
