I think you should check your X-Lite setup, look for "Send internal IP 
yes/no" and press F9 in X-Lite for debugging.

Hello,

my next problem is with SIP device behind NAT.

First few seconds of the call are OK. Astrisk is sending the packets to 
the public IP address of the FW/NAT (62.152.224.3). But this change in 
10 second and packets are send to the my public addres.(192.168.1.163).

in the sip.conf for the phone(X-Lite) is
[998]
type=friend
username=998
secret=<pokus>
canreinvite=no
host=dynamic
dtmfmode=rfc2833
mailbox=998
nat=1
callerid=0650199802

Can anybody explain me, why the dest IP will change from public one to 
the private one ?

	best regards
