SPA3102 firmware upgrade

    I've been reviewing my options with regard to upgrading my SPA3102
    firmware. There appears to be two firmware revisions available at - one version 3.3.6 and one 5.1.10.

    My SPA3102 is already at 3.3.6 (firmware "3.3.6(GW)" with a hardware
    revision "1.4.5(a)" to be precise), yet (a) I've never upgraded it
    in the couple of years I've had it, and (b) the release date for this
    software claims to be 21st July 2010 - just last month. (Provisioning
    is not enabled, in case anyone wonders!)

    So, could someone explain what the difference is between the 3.3.6
    firmware and the 5.1.10, please? Particularly whether they are for
    different hardware revisions, or whether 5.1.10 is really the latest
    version for a 3.3.6 box - and if so, why both versions are offered!

    Many thanks,

    It's less hassle to stick with 3.3.6 (GW)
    The "FXS Port Impedance" option for the UK is missing from the dropbox:
    under "Voice > Regional settings".

    If it's not broken .......

    There is a Cisco/Linksys (Sipura) forum at

    Mmmm, uh oh. Thanks for that heads-up.

    Well, IMO it is broken - don't you find the echo on the POTS line pretty
    unpleasant? I do (and my wife /detests/ it).

    In message <>
    Your line impedance setting predominantly affects how much echo
    the far end hears when talking to you. It also affects the level
    of sidetone, which is your voice coming back non-delayed. You
    always want some sidetone; it's very disconcerting not to have
    any, it's like talking into complete emptiness. As for how much
    "some" is: quite a lot, usually in the range -6 dB to -10 dB.

    When I say "non-delayed", that really applies to an analogue phone.
    A DECT handset introduces delays both ways between itself and the
    hybrid, so it might sound like echo, I suppose.
