Which Codec?

Discussion in 'UK VOIP' started by the hamiltons, Jan 21, 2006.

  1. Hi all-I'm using a Sipura SPA2000 with a satellite 128/512k connection.
    Obviously I suffer latency problems but I can work around this. My problem
    is incoming calls are fine but outgoing calls are very distorted. In the
    Sipura set-up I notice the codec in use is G723. The connection is capped at
    128/1gb a month so bandwidth is an issue,however I need to be heard! In
    which order do I start using the other codecs to start using more bandwidth.
    For those not familar with the Sipura the available codcs
    are;G711u,G711a, G726-16-24-32-40, G729a.TIA.

    In increasing order of bandwidth:
    G723
    G729a
    G726-16
    G726-24
    G726-32
    G726-40
    G711u/G711a
