Look at dispatcher - config.c and dispacher.c. http://sip-router.org/docbook/sip-router/branch/master/cfg_list/cfg_var_list.html#dispatcher.ping_reply_codes That page also gives more examples. I don't see a callback when variables in the config fw changes, so you need to get them with cfg_get before using if I understand it right. I will experiment and see if I can expose this in the snmp module. I don't see any Dispatcher-related variables in the MIBs, so that needs to be added. Time for me to learn about tables in NET-SNMP and MIBs. /O > > > Regards, > > Peter > > -- > Peter Dunkley > Technical Director > Crocodile RCS Ltd _______________________________________________ sr-dev mailing list [email protected] http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
