<p class="MsoNormal"><span style="color:#44546A">For the brocades they were placed topology wise in front of the SBCs so that all requests and replies cross the load balancer. You can do this by having the load balancer be the default gateway for the SBC’s.
It was pretty simple at least for the brocade configuration. Note that RTP traffic was not load balanced of course.<o:p></o:p></span></p>

<p class="MsoNormal">Has anyone had any success load balancing SIP? More specifically distributing SIP registrations across a number of access SBCs and maintaining persistence based on source IP. By maintaining source IP persistence subsequent calls would
go to the SBC to which they are registered. In this case each of several SBCs cache registrations for a single SIP registrar. Has anyone used F5 or Kamailio for this..or some other SIP proxy or load balancer?<o:p></o:p></p>
