    I have just set up my Zoom X5V with Sipgate works great now I've added an
    ADSL filter between it and the phone as it wasn't ringing on incoming calls
    at first. Anyway I was wondering what codec to use to obtain the best
    quality audio. I have a choice of G.711u, G729 and G7.11a.
    Thanks in advance.

    In order, G711a, G711u (although there's not a lot to choose between them)
    and G729.

    For tests please feel free to call my speaking clock on 1431320 (020 7043
    1320). Note that due to firmware limitations it will cut off after 30
    seconds, nothing I can do about it, sorry..!

    Hi Ivor, many thanks for the info, I've set up my router with the codecs in
    that order. Thanks for the speaking clock worked well. Good on ya for
    setting it up.

    Ms Simmons is sounding in good form today Ivor!

    I would say about 6dB louder than last time I tried.

    Is it my imagination, or have you tweaked her?

    No, nothing changed at this end. Maybe they've been doing some tweaking at
