i noticed that msilo generated messages include a Contact header such as:
Contact: sip:jh@test.fi;msilo=yes
according to rfc3428.txt this is wrong:
MESSAGE requests do not initiate dialogs. User Agents MUST NOT insert Contact header fields into MESSAGE requests.
if no one objects, i'll fix msilo module accordingly, i.e., remove contact header from msilo generated messages.
