[Serusers] who's controller?

[lakmal at lankacom.net]

Hi,

I have SER running. I noticed that on 2 occations a user by the id
<sip:controller at iptel.org> calling me. When I accepted the call nobody
talks, but the connection is established. Is this sort of a routine
checkup or something by iptel.org?




Regards,
Lakmal
