[OpenSIPS-Users] RTP Relay issue

Fri Sep 6 14:46:25 UTC 2024

Hi Răzvan,

I've just tested with version 3.4.8 and the situation has evolved.

This is what I have with a call of one side :

opensips conf:

$rtp_relay(iface) = "external";
$rtp_relay_peer(iface) = "internal";
rtp_relay_engage("rtpengine");

Debug result:

DBG:rtp_relay:rtp_relay_answer: leg=callee callid=[] ftag=[] ttag=[] 
type=[] in-iface=[external] out-iface=[external] ctx-flags=[] flags=[] 
peer-flags=[]

rtp_relay_list mi command:

[
{
"callid": "57c017bc5c8ccc3c5c29b2d57f6f0722 at x.x.x.x:5060",
"caller": {
"tag": "as2d4f2687",
"interface": "external"
},
"callee": {
"tag": "as2d4f2687",
"interface": "external"
},
"relay": "rtpengine",
"node": "udp:y.y.y.y:2223",
"set": 0,
"ctx": {
"from-tag": "as2d4f2687",
"to-tag": "DC09BE8B_nab_FFFF_isp_FFFF_cco_FFFF_igo_FFFF_mgt_401C"
}
}
]

And for a call from the other side:

opensips conf:

$rtp_relay(iface) = "internal";
$rtp_relay_peer(iface) = "external";
rtp_relay_engage("rtpengine");

Debug result:

DBG:rtp_relay:rtp_relay_answer: leg=callee callid=[] ftag=[] ttag=[] 
type=[] in-iface=[internal] out-iface=[internal] ctx-flags=[] flags=[] 
peer-flags=[]

rtp_relay_list mi command:

[
{
"callid": "0201FFFFF1F526A9",
"caller": {
"tag": "0E0AD956_nab_FFFF_isp_FFFF_cco_FFFF_igo_FFFF_mgt_4125",
"interface": "internal"
},
"callee": {
"tag": "0E0AD956_nab_FFFF_isp_FFFF_cco_FFFF_igo_FFFF_mgt_4125",
"interface": "internal"
},
"relay": "rtpengine",
"node": "udp:y.y.y.y:2223",
"set": 0,
"ctx": {
"from-tag": "0E0AD956_nab_FFFF_isp_FFFF_cco_FFFF_igo_FFFF_mgt_4125",
"to-tag": "as36a555a0"
}
}
]

It seems that with this version the code just take $rtp_relay(iface) 
value, put it into $rtp_relay_peer and ignore $rtp_relay_peer value.

Have you any other idea ?
