  • Question

  • Hello, I am using MS BW calculator and need to set a codec on sip trunk to provider to g.729, while codec between Mediation server and SBC is g.711. Has anyone met the same trouble?

  • G.729 isn't in the calc because Lync doesn't use it.  G.729 is compressed a bit so to calculate what you'd need you could do some math and pick maybe 30kbps or just ask your sip provider to do this for you.

    There are sites that can help too:
