Hello,
Certainly, here they are from opensips.cfg and I've included the
modparam in case they help:
loadmodule "db_mysql.so"
loadmodule "sl.so"
loadmodule "tm.so"
loadmodule "usrloc.so"
loadmodule "auth.so"
loadmodule "auth_db.so"
loadmodule "maxfwd.so"
loadmodule "mi_fifo.so"
loadmodule "nathelper.so"
loadmodule "perl.so"
loadmodule "registrar.so"
loadmodule "rr.so"
loadmodule "textops.so"
loadmodule "uri.so"
modparam( "auth", "nonce_expire", 30 )
modparam( "auth_db|domain|uri_db|usrloc", "db_url", "mysql://foo" )
modparam( "auth_db", "calculate_ha1", yes )
modparam( "auth_db", "password_column", "secret" )
modparam( "auth_db", "use_domain", 0 )
modparam( "auth_db", "user_column", "name" )
modparam( "mi_fifo", "fifo_name", "/tmp/opensips_fifo" )
modparam( "nathelper", "natping_interval", 240 )
modparam( "nathelper", "ping_nated_only", 1 )
modparam( "nathelper", "sipping_bflag", 1 )
modparam( "nathelper", "sipping_from", "sip:keepalive at foo" )
modparam( "nathelper|registrar", "received_avp", "$avp(i:42)" )
modparam( "perl", "filename", "/path/to/OpenSIPS.pm" )
modparam( "perl", "modpath", "/path/to/perllib" )
modparam( "registrar", "append_branches", 1 )
modparam( "rr", "enable_full_lr", 1 )
modparam( "usrloc", "db_mode", 2 )
modparam( "usrloc", "desc_time_order", 1 )
modparam( "usrloc", "nat_bflag", 1 )
modparam( "usrloc", "timer_interval", 5 )
Thank you!
