[SR-Users] Dispatcher and options_reply

Hello, So Im using dispatcher to poll SBC's behind my kamailio load balancer. What I need to do is get a count of how many "active" SBC's there are in the dispatcher module. ( how many SBC's are actively responding to their options ping ) so that I can then use this info when I reply to an OPTIONS on the load balancer. effectively , if there are no SBC's active, the LB needs to not reply to options. I COULD use ds_select_dst or something , but is that going to be overkill from a CPU perspective ? ( And I dont want ds_select_dst to do any modification to my otpions packets ) just wandering what everyone thinks the best way to achieve this would be. -- Sincerely Jay
