Hi, I'm trying to configure SS7 for the first time on a system that I cannot currently upgrade (ie. I need to use zaptel and Asterisk 1.4): asterisk 1.4.31 zaptel 1.4.12.1 libpri 1.4.11.5 libss7 1.0.1 (installed from source) At system startup I'm getting: ERROR[15475] chan_dahdi.c: Unknown signalling method 'ss7' and the Asterisk CLI does not contain any "ss7" or "zap" commands. How can I make sure Asterisk is loading the SS7 library? According to libss7, I should place "signalling=ss7" in /etc/asterisk/zapata.conf. Is that right? Do I need to recompile zaptel or asterisk AFTER I install libss7? Thanks Vieri
