[Freeswitch-users] ESL event on OPTIONS fail

Hello I would like to real-time monitor network reliability for each extensions on multiples freeswitch servers ( no shared core or sofia database ). Using ESL i can monitor users registrations and network lost ( by catching unregister event thanks to all-reg-options-ping ) But is it possible to make ESL event for each OPTION packet without reply or even better make an event if the latency is above a predefined threshold ? Thanks
