Hi Brian,
Thank you very much for your answer but both, Freeswitch and Kamailio have
public IPs, it's my NAT'd IP phone who has private IP but this is fixed by
Kamailio.
The problem is not the 1st call is failing ( the test is set that way), the
problem is FS answers back 482 when Kamailio tries a 2nd route ( or 3rd ) for
the same call...
Freeswitch is configured to use the Requested-URI sent by Kamailio:
<action application="bridge" data="sofia/external/${sip_req_uri}"/>
I noticed that there is no Log message in Freeswitch when receiving the INVITE
for the 2nd route.
The process in FS seems to be destroyed (11:46:21.396593) before the 2nd INVITE
is received (11:46:21.401419
).

==========================================
Looks like FS is behind nat. You need to set local-network-acl and
the ext-rtp-ip and ext-sip-ip so FreeSWITCH properly puts in the right
IP's in the via headers and sdp.
Please refer to internal.xml in the latest SVN for an example of how
to do this.
