Basically the scenario is that we want to utilize Quagga
via BGP to anycast an address, which addresses a glaring load balancing issue with have with people who use only A records.</span></p><p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p><p class="MsoNormal"><span lang="EN-US">Problem is anycast doesn’t work so well in this scenario, just by adding the Anycast as a listen address on the proxy. What we’d want to do is rewrite the SIP so that all responses come back out saying to use the ‘real
ip’.</span></p><p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p><p class="MsoNormal"><span lang="EN-US">So I have two variables – say REAL_IP_ADDRESS and ANYCAST_IP_ADDRESS – request will come in via ANYCAST, but I want all responses from then on to be via REAL_IP_ADDRESS. We have six Kamailio boxes in various geographical
locations, so the idea is they hit one based on closest, and we rewrite it so they end up with the real ip address to talk to. </span></p><p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p><p class="MsoNormal"><span lang="EN-US">Anyone done something similar?
