registration and header

Hello,
I use siproxd 0.5.13 and lib64osip2 2.2.2 on a mandriva spring ( 2007.1 ).
Then i try to register to the sip server ( asterisk ) with Express Talk from inside my lan ( 172.16.0.44 ) , i've got this log :

 siproxd: sock.c:125 received UDP packet from 172.16.0.44, count=399
 siproxd: accessctl.c:53 deny  list (SIP):*NULL*
 siproxd: accessctl.c:55 allow list (SIP):*NULL*

 siproxd: siproxd.c:348 ERROR:security_check_sip() failed... this is not good
 siproxd: siproxd.c:270 going into sipsock_wait 

I've try with x-lite too, and it's the same result : NULL To Header
What can i do to solve this ?
Thank's in advance
