Hi Ali,
For profiling, use the GW ID - as value for the profile - (you can
instruct DR to return the GW ID in an AVP) ; now, about the limit, use
the "attrs" from GWs to keep it

Hi Jeff,
Thank you for the reply but unfortunately this doesn't answer my
questions. I need to bind this to the drouting module, so when I call
do_routing, I need a parameter for set_dialog_profile for whatever
gateway do_routing() picks. That was my first and second questions.
Also in your case, where do you set $var(dlgsize_out)? where do you
get it from? How would you change it? I don't want to have to change
my script or restart opensips to change this.

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.

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?

Hi All,
I would like to limit number of concurrent calls to a
gateway in dr_gateways table (drouting module).
I have looked at the tutorial on the opensips webiste
(http://www.opensips.org/Resources/DocsTutConcurrentCalls)
and this is not the same.
I do create a dialog and then I do do_routing(). At this
point I don't know:
1- What parameters to pass to set_dlg_profile() to
increase the number of calls for whatever particular
gateway do_routing happened to select?
2- How to use get_profile_size() to see if the gateway has
reached it's maximum number of channels?
3- Where would be the best place to record and read the
max number of channels available for each gateway? some
place that I wouldn't need to do a db quey but I would be
able to make changes while opensips is running similar to
the drouting module parameters itself.
Any help/suggestion would be appreciated.
Thanks,
Ali Pey
