Actually kamailio routes any Request by SIP headers.
I suppose your porblem on some another point, independend of ICE or other
SDP content

Hello,
Yuriy Gorlichenko, first of all thank you for your attention.
What I'm trying to understand is; Is Kamailio delaying the referral of
INVITE when it arrives with ICE candidates? Because, when the INVITE
arrives without the ICE candidates, the INVITE is routed correctly.
When I send the INVITE with ICE candidates, Kamailio responds to me
"SIP / 2.0 100 trying - your call is important to us" and nothing else
happens, because this INVITE does not reach the other endpoint.
Initially, what I want is for endpoints to decide what to do with ICE
candidates.
In my kamailio.cfg, I have a configuration related to rtpengine
"rtpproxy_manage("co");", could this affect the behavior for INVITES
that contain ICE candidates? I tried to comment on that line, but the
problem continued.
# RTPProxy control and singaling updates for NAT traversal
route[NATMANAGE] {
#!ifdef WITH_NAT
if (is_request()) {
if(has_totag()) {
if(check_route_param("nat=yes")) {
setbflag(FLB_NATB);
}
}
}
if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)))
return;
rtpproxy_manage("co");
if (is_request()) {
if (!has_totag()) {
if(t_is_branch_route()) {
add_rr_param(";nat=yes");
}
}
}
if (is_reply()) {
if(isbflagset(FLB_NATB)) {
if(is_first_hop())
set_contact_alias();
}
}
#!endif
return;
}
Best regards

You can use rtpengine module for rewriting ICE
