I have this config:
WebRTC sipml5 -> Kamailio -> Asterisk -> Kamailio -> WebRTC sipml5
When placing a communication between two sipml5 points I get this errors:
ERROR: <core> [resolve.c:1733]: sip_hostport2su(): ERROR: sip_hostport2su:
could not resolve hostname: "df7jal23ls0d.invalid"
ERROR: <core> [forward.c:532]: forward_request(): ERROR: forward_request:
bad host name df7jal23ls0d.invalid, dropping packet
ERROR: sl [sl_funcs.c:387]: sl_reply_error(): ERROR: sl_reply_error used:
Unresolvable destination (478/SL)
If I place a comm between WebRTC sipml5 -> Kamailio -> Asterisk ->
Softphone (connected to Asterisk)
Everything works fine
I'm running RTPEngine as RTP Proxy for DTLS/SRTP issues
SIP INVITE signalling Ringing 180 message and 200 OK gets done fine
Any ideas where this issue might come from? Looks something related with
media traffic (RTP).
Kind regards!

You have to do nat traversal logic for signaling -- see default config
file for set_contact_alias() and handle_uri_alias().
Cheers,

Ok, I have adapted the default for set_contact_alias and handle_ruri_alias
(you meant ruri not uri, right? i cant find handle_uri_alias in the
nathelper module)
Now I've tried some new scenarios:
Using JSSIP instead of SIPML5
Calling with a peer connected to Asterisk directly to WebRTC client works
fine
The inverse scenario (from WebRTC client JSSIP to Asterisk peer) fine
Also tried sip softphone connected directly to Kamailio to WebRTC client
and works fine both ways
The problem ocurrs when I call from WebRTC client to WebRTC client
Both WebRTC client and SIP softphone (X-Lite) are being used from the same
PC
First I tryed the JSSIp functionality "hack_ip_in_contact"
