Ever Wonder Why?
The Voip vulnerability topic made me wonder, since a couple of these were VoIP vulnerabilities that didn't affect just Cisco, how come I never see Avaya, Nortel, or any other VoIP companies release security advisories? So Cisco gets punished just for being honest with their customers, whereas others never release a security advisory and they are not called out...nice.
you are mistaken
You make an eroneous assumption, in that you believe that all vendor 'do' VoIP exactly as Cisco does VoIP--- that's not the case. Avaya doesn't have some of the issues Cisco has because of the way our technology works and is deployed. Avaya's VoIP products work off a different OS, they use different technologies for controlling media-gateways, and [in my opinion] use more sound telephony feature set as the basis for our product. Can other vendors be subject DoS attacks and the like? Yes, but all IP-Telephony wasn't created equally, so we don't all have the same issues. fjm
