opsss, what the ****???

I use the following parameters in a LCR configuracion (I use m4):


modparam("lcr", "gw_uri_avp", "$avp(AVP_LCR_GW_URI)")
modparam("lcr", "rpid_avp", "$avp(AVP_LCR_RPID)")
modparam("lcr", "ruri_user_avp", "$avp(AVP_LCR_RURI_USER)")
modparam("lcr", "flags_avp", "$avp(AVP_LCR_FLAGS)")
modparam("lcr", "ping_interval", 10)
modparam("lcr", "ping_from", "sip:pinger at mydomain.org")
modparam("lcr", "ping_method", "PING")
modparam("lcr", "positive_codes", "501;200;404;401;407;403")
modparam("lcr", "negative_codes", "408;503")



As you say, the module doc doesn't talk about "ping" related
parameters... how can it be??? something happened to the module doc?

No, it just gives you the possibility of storing flags (1 or 0) of
each gateway. When a gateway is used, its flags are retrieved into
"flags" AVP:

  modparam("lcr", "flags_avp", "$avp(AVP_LCR_FLAGS)")
