i didn't get any response to this on users list. perhaps the question fits better to dev list: what would it take to make avpops module to print config file line number when error occurs? now i just get: Jun 24 14:13:43 host /usr/sbin/sip-proxy[29890]: ERROR: avpops [avpops_impl.c:1170]: ops_check_avp(): value types don't match -- juha
