That is correct. SNOM does send line ID as a parameter in the contact
when it registers with registrar. 
Contact: <sip:[EMAIL PROTECTED]:5060;line=819ctzmd>;flow-id=1;q=1.0;
        +sip.instance="<urn:uuid:57e98536-e146-4d1e-85ea-9fecb3d517dd>" 
This lineID is expected to be present in the request line for any
INVITE. If this is missing it moarns about the ID not being found. The
INVITE request line should look like 

INVITE sip:[EMAIL PROTECTED]:5060;line=819ctzmd SIP/2.0

I think when SNOM 360 register, it useses "lineid" in the Contact. So,it
might expect that information in the request URI while it's receiving
INVITE.

soft phone to SNOM 360.

        please find here the brief description of my set up and
configuration . the following are ......

                 1. brekeke SIP server
                           ( where i have created account for both snom
user and X-lite user)

                 2. Snom 360 is able to make call to X-lite, and the RTP
is through.
