Hi Robert,

See the new blog post about how a balancer should be inserted into the SIP flow:

https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fblog.opensips.org%2F2017%2F06%2F28%2Ftraffic-balancing-the-insertion-into-the-sip-flow%2F&data=02%7C01%7Crmundkowsky%40ets.org%7C82012f772567476f77a308d4be5ddf7d%7C0ba6e9b760b34fae92f37e6ddd9e9b65%7C0%7C0%7C636342757777029125&sdata=xseFlfBeoa0hoS1sp01WsrFIeO71etgACzp9BPj6KcY%3D&reserved=0
