Re: [Serusers] Round-Robin/Random forwarding

Module "exec.so" provides the server with external scripting capabilities. In your case, look at exec_dset ... relevant example usage is included with the distribution: /ser-0.8.12/examples/exec_dist.cfg Jamie

Hi, We have several gateways all with the same routes. Anyone knows how to distribute calls from SER in a round-robin or some random fashion to them. The rewriteuri and forward functions only allow one static route.

It would be nice to have something like rewriteuri_randomselect("sip:gateway1.pfluger.de:5060", "sip:gateway2.pfluger.de:5060", "sip:gateway3.pfluger.de:5060", "sip:gateway4.pfluger.de:5060");

Any solution to this?

Thanks,

Henrik

This is what we currently do to send calls to a single gateway:

# PSTN resolution if (uri=~"^sip:[0-9]+@") {

    # request digest authorization
    if ((method=="INVITE") && !www_authorize("pfluger.de", "customer"))

{ www_challenge("pfluger.de", "0"); break; }

    # make sure from user matches authenticated user
    if (method=="INVITE") {
            if (!check_from()) {
                    sl_send_reply("403", "From user does not match

authenticated user"); break; } }

    # Forward PSTN call
    xlog("L_CRIT","[%Tf]: %rm %ru: Forwarding to PSTN gateway\n");
    rewriteuri("sip:gateway.pfluger.de:5060");

}
