Hi Sammy,

I was thinking to simplify a bit this and to add to LB module a function like lb_is_from_peer() , to test if an IP + port matches on of the peers defined in LB...

Hi Miha,

I do exactly what Bogdan said, but using DB connecitons. IF its an Initial INVITE connect to DB and query table load_balancer and see if the source ip of INVITE matches any of the load_balanaced FS servers then I know that its from inside-media-serves to outside.

The next thing is identifying what original destination your FS was trying to send the calls to i.e carrier-ip / uri !

So in your FS dialplan add a sip header where you store the real destination of the SBC/trunk and once you are in the IF condition where you detect your internal FS servers, strip off that header change the $ru and t-relay the call !!

phone(dial 007@FS )<===> FS (P-Real-DST: CAR.RIE.R.IP & dial 007@OpenSIPS )<====>OpenSIPS([email protected])<===> ITSP([email protected] )

I hope this is what you wanted.

Regards,
Sammy

    Hi Bogan,

    that is a bit tricky as phones are registering on Opensips server.
    If I make this that the phones will not register as FSs servers
    are on different ips than SBC.

    What would you sugget?

        Hi Miha,

        Well, in your script, when dealing with the initial requests,
        just look at the source IP of the INVITEs - if from SBC, do
        the lb stuff, otherwise route it back to SBC.
           if (src_ip==11.22.33.44) {
               # do LB
           } else {
                # send to SBC
           }

        Regards,
        Bogdan

            Hi,

            as I am dealing with opensips for the first time I would
            ask you for a little help.
            I have installed and configured opensips that works like
            load_balancer
            (http://wiki.freeswitch.org/wiki/Enterprise_deployment_OpenSIPS).

            I tested it and works. Than I have created siptrunk and
            point it to Opensips. Opensips was balacing the calls to
            one of the FSs, that I have set in opensips configuration.

            How can I now configure opensips, if the call is made from
            FS, that opensips will send it to SBC (from where sip
            trunk is made), so that the calls will be working in both
            direction?


            Thanks!

            Miha
