the contact must be at least user1 at 192.168.100.1;transport=TLS, and 
usually also a port is specified.

Thus I guess it happens as you directly dial the contact without

PS: Of course a dump would help:

"ngrep -W byline -t port 5060"

if you use TLS use port 5061 and use the NULL encryption schema in TLS 
settings.
