[Serusers] Presence- Subscribe request issue

[Daniel Serrano]

Dear all,

I'm running a SER 9.6 in order to handle IM and presence.  IM are 
working just  great. I have an issue with the presence. At the moment of 
receive a SUBSCRIBE message, the SER  respond with a 400  BAD REQUEST 
and the message "Error while parsing headersServer: Sip EXpress router 
(0.9.6 (i386/linux))" inside.   Any ideas?
Thanks in advance for the help.
