Also, an interesting thing - if you can see in Kamailio log, a check of the
proto of user "300" is being made. But 300 is $tU, and $tU proto is being
checked only if source IP is asterisks IP.
Here's the part of config where rtpengine is engaged (in NATmanage route)
if((src_ip==10.0.0.87))
{
xlog("L_NOTICE","====== select proto from sipusers where
name=$tU");
sql_xquery("ca_asterisk", "select proto from sipusers where
name=$tU", "ra");
xlog("L_NOTICE","===== $tU has proto $xavp(ra=>proto)");
if ($xavp(ra=>proto)=="ws")
{
xlog("L_NOTICE","===== $tU has WEBSOCKETS");
rtpengine_manage("trust-address replace-origin
replace-session-connection ICE=force RTP/SAVPF");
}
else
{
xlog("L_NOTICE","===== $tU has NO fucken WEBSOCKETS");
rtpengine_manage("trust-address replace-origin
replace-session-connection");
}
} else {
xlog("L_NOTICE","====== select proto from sipusers where
name=$fU");
sql_xquery("ca_asterisk", "select proto from sipusers where
name=$fU", "ra");
if ($xavp(ra=>proto)=="ws")
{
xlog("L_NOTICE","===== $fU has WEBSOCKETS");
rtpengine_manage("trust-address replace-origin
replace-session-connection ICE=force RTP/AVP");
}
else
{
xlog("L_NOTICE","===== $fU has NO WEBSOCKETS");
rtpengine_manage("replace-origin
replace-session-connection RTP/AVP");
}
}
