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

[Jeff Pyle]

Ali,

Oops, I had some inconsistent rewrites.  So much for improved readability.
 Consider this instead:

        # Check to see if we're at maximum capacity for this gateway
        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:gw_maxcalls)) {
                        # We're full, so cycle around to the next gateway...
                }
        }

That should make more sense.


- Jeff
