[OpenSIPS-Users] Max Concurrent Calls with drouting and dialog modules

[Jeff Pyle]

Hi Ali,

I have the same application.  A little before the t_relay() to the gateway,
I have:

        # Check to see if we're at maximum capacity
        if !(get_profile_size("outbound", "$avp(s:dlgid_out)",
"$var(dlgsize_out)")) {
                xlog("L_INFO", "Couldn't get dialog size, continuing
route-out\n");
        } else {
                if (is_avp_set("$avp(s:gw_maxcalls)") && $var(dlgsize_out)
>= $avp(s:car_maxcalls)) {
                        # Move on to the next carrier...

                }
        }
        # Continue towards t_relay() for this gateway...

This verifies our counts to make sure we have room.  If I'm at that value
(or over) I cycle around and select the next gateway.  If all is well
I run set_dlg_profile("outbound",
"$avp(s:dlgid_out)").  Since you're using drouting, perhaps you'll use
another variable here in place of $avp(s:dlgid_out).

I implement serial forking for my gateways.  In the selected failure_route
I run unset_dlg_profile("outbound", "$avp(s:dlgid_out)").  If I'm in this
section I know the call has failed, so I want to remove its count from the
profile.

This configure is old enough to be pre-drouting but the concepts are still
the same.

Is that helpful?
