Hi,
while strolling through my sip server logile ive came accross some strange unauthorized sip messages originating from "scan.qualsys.net": (ip address has been logged to)
--- OPTIONS sip:scan.qualys.com SIP/2.0 Via: SIP/2.0/UDP scan.qualys.com:5060;branch=z9hG4bKnashds7 Max-Forwards: 70 To: Foo sip:foo@scan.qualys.com From: Foo sip:foo@scan.qualys.com;tag=456248 Call-ID: 843817637684230@998sdasdh09 CSeq: 1826 OPTIONS Accept: application/sdp Content-Length: 0 ---
These packets could be found in ALL our SIP Proxy logs and they are clearly unauthorized.
Has anyone a idea what this could be about or found similiar sip messages in his log?
