__________________________________________________________Hello,
generally speaking, calling rtpengine_manage() should be enough in most cases. Compare e.g. to the kamailio default configuration and the docs of the module:
https://kamailio.org/docs/modules/5.8.x/modules/rtpengine.html#rtpengine.f.rtpengine_manage
Cheers,
Henning

Tihomir,
Actually, yes, You need to call rtpengine_delete()
Like this
request_route {
....
if (is_method("CANCEL")) {
if (t_check_trans()) {
xlog("L_INFO", "[REQUEST_ROUTE] Relaying in-transaction CANCEL\n");
# Free previously reserved resourced
rtpengine_delete();
...
}
exit;
}}
route[WITHINDLG] {
if (has_totag()) {
if (loose_route()) {
...
if (is_method("BYE")) {xlog("L_INFO", "[WITHINDLG] In-dialog BYE. Invoking rtpengine_delete\n");
rtpengine_delete();
}...
}
failure_route[MANAGE_FAILURE] {
if ($rs > 299) {
xlog("L_INFO", "[MANAGE_FAILURE] Transaction failed with $rs > 299, invoking deleting of call on rtpengine\n");
rtpengine_delete();
}}
This is where I do this usually, but you might need to adapt it to your cases.

Hello,
I'm using Kamailio + RTPEngine. Everything works well except one thing. I noticed rtp sessions are not being deleted after call termination. Instead, they remain lingering on RTPEngine waiting for a timeout.

I'm using rtpengine_manage in two routes "route[RELAY]" and onreply_route[MANAGE_REPLY] . Do I need to add a specific rtpengine_delete somewhere ?
route[RELAY] {
...
$xavp(r=>$T_branch_idx) = "replace-origin replace-session-connection";
if (!nat_uac_test("8")) {
$xavp(r=>$T_branch_idx) = $xavp(r=>$T_branch_idx) + " trust-address";
}
if (!has_totag()) {
xlog("L_INFO", "NEXIOS: proto = [$proto], ru = [$ru]");
if ($proto =~ "ws" && !($ru =~ "transport=ws")) {
xlog("L_INFO", "####################### FROM WS to any ########################\n");
$xavp(r=>$T_branch_idx) = $xavp(r=>$T_branch_idx) + " rtcp-mux-demux DTLS=off SDES-off ICE=remove RTP/AVP direction=external direction=internal";
} else if (!($proto =~ "ws") && $ru =~ "transport=ws") {
xlog("L_INFO", "####################### FROM any to WS ########################\n");
setbflag(FLB_TOWEBRTC);
$xavp(r=>$T_branch_idx) = $xavp(r=>$T_branch_idx) + " rtcp-mux-offer generate-mid DTLS=active SDES-off ICE=force RTP/SAVPF direction=internal direction=external";
} else if (($proto =~ "udp") && $ru =~ "transport=udp" && $fs =~ "MY_IP2_ADDR") {
xlog("L_INFO", "####################### FROM ?? to ?? $ru ########################\n");
}
}
# we engage RTPEngine
if (has_body("application/sdp")) {
xlog("L_INFO", "NEXIOS: # $xavp(r=>$T_branch_idx) #\n");
rtpengine_manage($xavp(r=>$T_branch_idx));
}
if (!t_relay()) {
sl_reply_error();
}
exit;
}
onreply_route[MANAGE_REPLY] {
...
$xavp(r=>$T_branch_idx) = "replace-origin replace-session-connection";
if (!nat_uac_test("8")) {
$xavp(r=>$T_branch_idx) = $xavp(r=>$T_branch_idx) + " trust-address";
}
if (has_totag()) {

setbflag(FLB_TOWEBRTC);
$xavp(r=>$T_branch_idx) = $xavp(r=>$T_branch_idx) + " rtcp-mux-offer generate-mid DTLS=active SDES-off ICE=force RTP/SAVPF direction=internal direction=external";

}
}
if (has_body("application/sdp")) {
xlog("L_INFO", "onreply_route # $xavp(r=>$T_branch_idx) #\n");
rtpengine_manage($xavp(r=>$T_branch_idx));
}
}
Any ideas are appreciated.

Tihomir.
