Hi Marek,
Could be that your rtpengine sessions are not deleted correctly in some cases.
You can list the sessions with "rtpengine-ctl list sessions all" and check the callids there with your cdrs and check the "mark for deletion" row.
rtpengine AFAIK keeps the deleted sessions in the list and remove it then from time to time.
Which is normally not a long period (not sure every 30 seconds or longer).
Anyhow if the number of rtpengine sessions grows up and your dialog did not match with that, than it could be an issue with your config how you control rtpengine.
Or your dialog counter is not corrected.
Kind regards
there is some problem problem with rtpengine-ctl list numsessions
and caching.
i have
Current sessions own: 719
Current sessions foreign: 0
Current sessions total: 719
but current calls is maybe around 50
i wil check the prometheus module
thanks
