Hi, I can not load chan_ss7.so module from asterisk-1.4 with dahdi (instead of zaptel). Chan_ss7-1.1 source code was compiled with DAHDI flag set and dahdi include path. Here the error from asterisk console: [Jul 10 18:07:47] ERROR[8026]: transport.c:180 openchannel: Unable to open /dev/zap/channel: No such file or directory. [Jul 10 18:07:47] ERROR[8026]: chan_ss7.c:842 ss7_load_module: Unable to initialize ISUP. I have these modules loaded: # lsmod Module Size Used by wcte11xp 26400 0 dahdi_dummy 7752 0 dahdi 188752 2 wcte11xp,dahdi_dummy and these devices were created: # ls -l /dev/dahdi/ total 0 crw-rw---- 1 asterisk dialout 196, 1 Jul 10 17:36 1 ... crw-rw---- 1 asterisk dialout 196, 31 Jul 10 17:36 31 crw-rw---- 1 asterisk dialout 196, 254 Jul 10 17:32 channel crw-rw---- 1 asterisk dialout 196, 0 Jul 10 17:32 ctl crw-rw---- 1 asterisk dialout 196, 255 Jul 10 17:32 pseudo crw-rw---- 1 asterisk dialout 196, 253 Jul 10 17:32 timer How can i resolve this problem?
