60+ Devices In Confbridge And Dropping Audio
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

What else have you tried ? jitterbuffer ? mixing_interval ? codecs ?

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

The “timing test” CLI command will state it. Does the VM have guaranteed resources?
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
