    The reported problem is with the Skype software. SIP is a protocol. There's
    no useful comparison to be made.

  4. Aware that Skype is a proprietary system whilst SIP is an open
    protocol.

    Reported in above story that Skype has a habit of port hopping to dodge
    firewalls presumably to make user setup easy, along with large userbase
    makes it attractive to hackers.

    As anything takes off it will become target of attacks, happens with
    browsers all the time, Firefox has had quite a few security
    vunerabilities patched recently.

    Seem to remember a variant of PGP being introduced to allow secure,
    scrambled, voice communication.

    Just wondering if there are yet any reported attempted attacks on SIP
    based systems be it `tapping` or exploitation of SIP clients to run
    malicious code?

    Thanks

    Some resources related to VoIP security may be found at

    http://www.voipsa.org/

    There you will find a recent publication, the Threat Taxonomy document,
    which identifies and discusses what that organisation perceives the
    threats to VOIP security to be.

    Also of interest is
