Are you sure these belong to the same call? With the call IDs and tags
being different and all...
My Kamailio code:
route[GET_ICE] {
if ( $proto == "wss" ) {
if (is_ip_rfc1918("$si")) {
$dlg_var(ice) = " ";
} else {
$dlg_var(ice) = " ICE=remove RTP ";
}
} else {
$dlg_var(ice) = "ICE=FORCE";
}
}
You mention WebRTC <> Asterisk, but I assume you really want to bridge
it to plain SIP/RTP? Making that work requires more than just making ICE
work on one side.
WebRTC requires a specific set of features, and so offers *going to*
WebRTC should have the following options set:
transport-protocol=UDP/TLS/RTP/SAVPF ICE=force trickle-ICE rtcp-mux-offer
rtcp-mux-require no-rtcp-attribute SDES=off generate-mid
If your version of rtpengine is recent enough, a convenience flag
`WebRTC` is provided that enables all of these in one go.
Offers *going to* plain SIP/RTP generally require removal of these
features, depending on how picky the intended recipient is and what
features it supports. Generally you want to remove SRTP encryption, ICE,
and RTCP multiplexing:
transport-protocol=RTP/AVP ICE=remove rtcp-mux-demux
Subsequent offers (re-invites) and answers (200 OK etc) may omit any or
all of these.
Good luck
Cheers
