I am using asterisk 18.14.0 and chan_sip. confbridge has dsp_drop_silence=yes The conf joins all the endpoints in a one-way conf.

60+ devices and packets choppy or dropping audio.

The CPU is decent at Intel(R) Xeon(R) CPU E3-1240 v5 @ 3.50GHz

What else might I tweak to get this working without audio dropping ?
not much else is running on the server besides – asterisk.

Thanks

Jerry

  • I did just now change the mixing_interval to 40. Asked them to try again.

    WHich setting has the BIGGEST impact ? (typically)

    For codec all the endpoints are just ulaw and alaw.

  • What is a one-way conf?

    How have you determined the packets choppy/dropping audio?

    Is it virtualized? What timer is being used?

  • one way conf is ME – setting up users to be Muted.
    [ConfUserMuted]
    type=user quiet=yes startmuted=yes announce_only_user=no announce_user_count_all=no announce_join_leave=no

    The people at that environment shared that the audio is choppy or drops out.

    The server is Virtual server. How do you tell what “timer” is used ?

    Thanks

  • resources?

    timing test Attempting to test a timer with 50 ticks per second. Using the ‘timerfd’ timing module for this test. It has been 1000 milliseconds, and we got 50 timer ticks
