    VOIP from your own ISP is secure
    (Magnet, Smart, eircom, UPC(NTL/Chorus), Digiweb all offer secure VOIP on their own networks).

    Third party VOIP is not secure:

    Thats a big statement unless you happen to know the in depth details of exactly how each of those operators VoIP services work. And of course another user on the same ISP or an employee of one of the ISPs would never think to try and listen in.

    True enough - but I think he is referring to VoIP providers that are not ISP's & specifically where the user has to connect over the internet.

    e.g, DSL is reasonably secure (provided the VoIP packets are secured at the exchange). Same for fibre. The difficulties arise when the network between the VoIP user & the VoIP provider is over the internet.

    Still, to be on the safe side, you should never say anything on a comms link you don't want the world to know, regardless of how secure it is supposed to be ;)

    Well I'm pretty sure 4 of the 5 providers originally mentioned assign public IP addresses to their customer's broadband connections (I think Digiweb may assign a private IP address for the VoIP on their router) so their VoIP traffic is on the internet straight away; if it's got a public IP it's on the internet. Apart from that in a lot of cases the traffic between those same ISPs and 3rd party Irish VoIP operator will travel over INEX so the call traffic traverses exactly the same amount of public internet irrespective of whether the VoIP service is from an ISP or a 3rd party Irish VoIP operator.

    Purely software based services, such as Skype and others, are the only popular public VoIP services that can claim a modicum of security since they are able to use personal computer endpoints to encrypt traffic. Stating that one SIP based VoIP service is more secure than another's without providing an explanation of the non-standard measures taken to secure the SIP network is FUD.
