[SR-Users] Help with rtpengine_delete()

Hello everyone! I've been struggling with a kamailio scenario with the rtpengine_delete. My scenario is the following: I've setup a Kamailio multihomed, since some of my vendors has provided us a direct link using a different local subnet in eth2 and I have my public IP in eth1. The kamailio i've been working on is using app_lua module. SIP A <---------> 200.XXX.XXX.14 (eth1) [Kamailio 5.6] (eth2) 10.203.5.8 <------> Vendor 10.203.5.20 100.XXX.XXX.22 Basically, I receive a call from public IP eth1 and according to the logic from the vendor I forward statefully the call to 10.203.5.20 in second branch. I've been reading a lot of issues and documentation such as:[#840 rptengine], [#875 rtpengine] and [#2222 kamailio], but I don't really get working the rtpengine_delete() correctly, since I go to netstat -plan|grep rtpengine and I see some sessions still that are not freed. My second case is the following when I receive a 503 from another GW: SIP A <---------> 200.XXX.XXX.14 (eth1) [Kamailio 5.6] (eth1) 200.XXX.XXX.14 <-----------> Vendor GW 233.XXX.XXX.19 100.XXX.XXX.22 In that case I still see the rtpengine ports, mostly with my public IP 200.XXX.XXX.14 but some of them with the LAN 10.203.5.8 IP. Also, something curious I see on my 2nd use case is the following: https://pastebin.com/raw/B4vCgExX So, it would be great if someone can point me to the right direction, how and when I should use rtpengine_delete in order to finish the rtpengine sessions correctly and the ports can be freed up. Any help will be great!
