  1. There’s an excellent paper on availability and reliability of VoIP that I recommend: Assessment of VoIP Service Availability in the
    Current Internet

    Its conclusion is:
    Overall, we observe that the call success
    probability at around 0.5% and call abortion probability
    at about 1.5%, resulting in a 98% net availability, which is still
    some steps away from what the PSTN offers today (three to
    four 9’s), but already comparable to the availability of mobile
    telephone networks (around 97% to 99%).

    My take is that users only accept poorer quality if it is (more than) offset by a compelling feature. Example: mobile quality is worse than fixed line but that is the price to pay for mobility.
    What is the deal for VoIP?

  2. Instead of drinking the cool-aid of PSTN replacement and PSTN interconnect, if we consider IP Communication where by two (or more) individuals communicate via text, speech, image and screen sharing etc., then the paradigm changes. The user may be willing to live with less reliability because the new mode of communication allows different form and experience. (Just like people agree to live with lower quality of cell phones.) The tragic flaw is in trying to replace (that means we have to replicate) PSTN. The irony is that VoIP proponents think PSTN is dead, but they keep PSTN in their radar all the time.

  3. the question is not that we should have wireless back-up, but instead if we want VoIP to quack like PSTN, well then it has to be as good as PSTN. sorry but don’t buy the argument of having back-ups. Maybe IP should instead by integrated communication on IP
