Hi All I have a FS cluster behind two OpenSIPS proxy, the incoming calls is load balance and failover to FS cluster by OpenSips, It works well. The problem is, the outbound calls from FS must also route throw then OpenSIPS servers. So, does FS servers can loadbalance the outbound calls between the two OpenSIPS servers and failover if one of the Opensips server is down? -- Lei.Tang lei.tlfly@gmail.com
