Hi Marek,

I assume you have something to handle failed/error'd sessions also?

Maybe use this for anything >400 do a rtpengine_manage()

https://kamailio.org/docs/modules/devel/modules/tm.html#tm.f.t_get_status_co...

Looks like it is a couple of things taking (and holding onto) the ports.

hi,

added

route[WITHINDIALOG] { if (loose_route()) { ...

if (is_method("BYE|CANCEL")) { rtpengine_manage(); } ...

now i see numbers in

rtpengine_closed_sessions_total{reason="terminated"} 6436

rtpengine_request_seconds_total{proxy="127.0.0.1",request="delete"} 17.559471

BUT

number for used RTP ports is still very high (from my point of view)

like ~2000 for 100 simult calls

rtpengine-ctl params current | grep delete delete-delay = 0

Hi Marek,

It looks like a missing rtpengine_manage/ rtpengine_delete somewhere.

I assume you have them in for any BYE/CANCEL you get and for any sip errors in your script?

Plus a low delete-delay in the rtpengine.conf?

hi,

i have open around ~8000 rtp ports for around ~200calls (in peak)

with this statistic (current data, not from peak)

rtpengine_closed_sessions_total{reason="rejected"} 0 rtpengine_closed_sessions_total{reason="timeout"} 237405 rtpengine_closed_sessions_total{reason="silent_timeout"} 103 rtpengine_closed_sessions_total{reason="final_timeout"} 0 rtpengine_closed_sessions_total{reason="offer_timeout"} 0 rtpengine_closed_sessions_total{reason="terminated"} 0

rtpengine_request_seconds_total{proxy="127.0.0.1",request="offer"} 539.270967 rtpengine_request_seconds_total{proxy="127.0.0.1",request="answer"} 367.237641 rtpengine_request_seconds_total{proxy="127.0.0.1",request="delete"} 0.000000

is it normal? (large number of timeouts, "zero" terminated)

or i have missing rtpengine_manage (rtpengine_delete) somewhere?

(os rocky 9.2, kamailio 5.6.4, rtpengine 11.3.1)

thanks

Marek
