[Serusers] Round-Robin/Random forwarding

Hi, We have several gateways all with the same routes. Anyone knows how to distribute calls from SER in a round-robin or some random fashion to them. The rewriteuri and forward functions only allow one static route. It would be nice to have something like rewriteuri_randomselect("sip:gateway1.pfluger.de:5060", "sip:gateway2.pfluger.de:5060", "sip:gateway3.pfluger.de:5060", "sip:gateway4.pfluger.de:5060"); Any solution to this? Thanks, Henrik This is what we currently do to send calls to a single gateway: # PSTN resolution if (uri=~"^sip:[0-9]+@") { # request digest authorization if ((method=="INVITE") && !www_authorize("pfluger.de", "customer")) { www_challenge("pfluger.de", "0"); break; } # make sure from user matches authenticated user if (method=="INVITE") { if (!check_from()) { sl_send_reply("403", "From user does not match authenticated user"); break; } } # Forward PSTN call xlog("L_CRIT","[%Tf]: %rm %ru: Forwarding to PSTN gateway\n"); rewriteuri("sip:gateway.pfluger.de:5060"); }
