Dear All, I am a starter on Freeswitch although I have telecoms experience for a long time I am trying to set-up a Freeswitch server with a Digium TE110P ISDN PrI E1 card. I have installed DAHDI Drivres and the card is discovered OK. I have also installed the libpri library and activated mod_freetdm. When I run the freeswitch I can see that my span is defined when I connect disconnect the cable I recieve alarms as below 2011-09-10 16:47:27.948506 NOTICE mod_freetdm.c:1819 Alarm raised on channel 1:1 2011-09-10 16:47:27.948506 WARNING ftmod_libpri.c:1419 channel 1:1 (1:1) has alarms!
