Hello,

        

        Indeed, we had some discussions with Ken Rice about
        interconnecting OpenSIPS and FreeSwitch. The main idea is to
        make use of the Load-Balancer module in OpenSIPS (please note
        this is not a simple dispatcher or probabilistic/hashing
        routing, but actually a LOAD based routing engine) and have this
        LB module connected into FreeSwitch to collect information about
        real load on FS (currently, LB module in OpenSIPS counts as load
        the number of ongoing calls). But as here suggested, the load on
        FS can be evaluated based on CPU/memory usage or any other
        internal FS parameters which may be relavant.

        

        The interconnection between OS and FS can be either via one of
        the FS APIs (having the two software talking directly) or, as
        Jay suggested, directly via SIP OPTIONS (when to add the load
        info in replied can be determined based on the src IP of the
        OPTIONS request).

        

        Regards,
