[SR-Users] ERROR: <core> [resolve.c:1733]: sip_hostport2su(): ERROR: sip_hostport2su: could not resolve hostname: "df7jal23ls0d.invalid"

[Manuel Camarg]

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"
http://jssip.net/documentation/0.3.x/api/ua_configuration_parameters/#parameter_hack_ip_in_contact

But without that property set:

I'm a little bit stucked with this :(
