[SR-Users] Re: Kamailio not deleteing rtp sessions

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.

rtpengine-ctl list totals tells me every session went to 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)

            } 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()) { xlog("L_INFO", "onreply_route proto = [$proto], ru = [$ru]"); if ($proto =~ "ws" && !($ru =~ "transport=ws")) { xlog("L_INFO", "onreply_route ####################### FROM WS to any ########################\n"); $xavp(r=>$T_branch_idx) = $xavp(r=>$T_branch_idx)

            } else if (!($proto =~ "ws") && $ru =~ "transport=ws") {
                    xlog("L_INFO", "onreply_route

                    setbflag(FLB_TOWEBRTC);

    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.

Regards, Tihomir.
