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"

But without that property set:

I'm a little bit stucked with this :(

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

Cheers,
Daniel
