[OpenSIPS-Users] Wrong Contact in location table

[Dragomir Haralambiev]

Hi,

Thanks for your email.

Here is part of my location table:

         contact_id  username   domain  contact
                                         received  path    expires
         q  callid                                              cseq
last_modified         flags  cflags     user_agent
socket                   methods  sip_instance  attr

Why "received" field is blank?
Where could be the problem?
