Solved Registration attempts all over from 127.0.0.1

[Richard P OConnor]

Greetings Everyone !

Just got in and started reviewing my logs . Found a number of these registration requests as I have no idea who sp9 isa yet there are quite a few attempts to register from different sip names ! Must be 50 of them all in about 10 minutes !
The example shows a reg attempt form [email protected]

Any way to block these ?
Where are they coming from ?
My network is pretty secure albeit what I don't know \
Running a network trace as we speak

Thx !

It' a "system" log regarding Shared Parking.

What leejor said, SP stands for Shared Parking, so nothing to worry about.
