track source of a strange portscan / portmap attack -- 2

Job Description:

Hi I have an ongoing problem

from few hours.

My server appears to be performing a portscan

toward 'random' ip addresses and udp ports.

The process that is sending those packets is Asterisk

which was already at version 16.29

and I've upgraded it to the last version, 16.30

but the problem persists.

I can't provide ssh access to the server

but I can provide whatever packets captures you prefer.

I'd like to know the source of the problem,

if it's some virus in the office of the client

or some external attack.

Max 100 euros.

Aptitudini: Asterisk PBX, VoIP, Administrare rețea, Securitatea internetului, Network Security
