Hi Alex,
It's on the page that you linked to: "This is supported by all rtpengine
commands except rtpengine_manage()."
Thanks.

Hi David,
Whence the impression that sets aren't compatible with rtpengine_manage()?
https://kamailio.org/docs/modules/5.7.x/modules/rtpengine.html#rtpengine.f.…
"Sets the ID of the RTP proxy set to be used for the next
rtpengine_delete(),
rtpengine_offer(), rtpengine_answer() or rtpengine_manage() command.
The parameter
can be an integer or a config variable holding an integer."
Or are you using an earlier version of Kamailio in which this may not have
been true?

Hi Alex,
Thank you for the reply. We use a large weight of 99999999 to send
almost all
calls to the 22.x and 33.x servers without using sets. We
avoided sets because our Kamailio configuration uses rtpengine_manage(),
which according to the documentation is not compatible with
set_rtpengine_set(). I'll try it without the 11.x server and the large
weights, and see if the calls are evenly distributed between the 22.x and
33.x servers then.
Thanks again.

Hi,
From the docs:
"The balancing inside a set is done automatically by the module based on
the
weight of each RTPEngine from the set. The default weight is 1, if
another RTPEngine should be used twice as often as the first one, one would
specify the weight 2 for this server, for example."
I am unsure as to what effect such large values as 99999999 might have
on this
arithmetic.
It seems to me that if what you really want to accomplish is to evenly
distribute
calls between 22.22.22.22 and 33.33.33.33, with 11.11.11.11 only
as a last-resort backup, then you should put the first two into one naive
set without any weights, e.g.
modparam("rtpengine_sock", "1 == udp:22.22.22.22:7724 udp:
33.33.33.33:7724")
Then put 11.11.11.11 into a set of its own:
modparam("rtpengine_sock", "2 == udp:11.11.11.11:22724")
By default, set 1 should be invoked:
set_rtpengine_set("1");
rtpengine_{offer,manage}("...");
According to the docs, rtpengine_offer() will return a negative value if
there is
a failure of both:
"The function will return true on success and false (-1) on various
failures, like
using rtp_engine_offer() on a SIP MESSAGE
request or communication
with rtpengine fails."
Presumably, rtpengine_manage() does the same. Accordingly, you can do
something
like:
set_rtpengine_set("1");
if(!rtpengine_offer("...")) {
if($rc == -1) {
set_rtpengine_set("2");
rtpengine_offer("...");
}
}
Exact details and your mileage may vary.

anyone please tell me why? The rtpengine server at 11.11.11.11 is intended
to only receive calls if the other two are offline. Thank you very much.
