We have currently dispatcher running for single domain, but in future we have more domain coming so i want to do multi domain dispatching for example dispatcher redirect request for foo.com to foo.registar and bar.com to bar.registar SIP server currently we have following code in dispatcher logic. what should we do to handle multi-domain if(!ds_select_dst("1", "2")) { # if we are here that means no destination is available. We notify the user by 404 and exit the script. xlog("L_NOTICE", "No destination available!"); send_reply("404", "No destination"); exit; }
