I would try adding this to all of your user profiles (type = user) and
see if that improves things.

Kind regards,

Thanks - so based on this wiki - seems like "The only functionality that
requires internal timing is IAX2 trunking" - which I am not using .
Just ConfBridge... And getting crappy audio with about 80 devices and a 1 -
way conf.

other thoughts on what is happening ?

Hi,

Dahdi timing is for dahdi hardware. See here: 
https://wiki.asterisk.org/wiki/display/AST/Timing+Interfaces 


You could check your asterisk modules using "module show" on asterisk cli.

Sounds like you might be doing transcoding, which might be the cause of your 
problems. Are you using the same codec for all calls? If so - which one? I'm 
not 100% sure about this, but asterisk might be using slin internally for the 
conf bridge, which means it might have to do some expensive transcoding on the 
receiving and then again on the sending end. You could check your transcoding 
times with "core show translation recalc".

Regards,
Stoyan

noload = res_timing_timerfd

However, it's unlikely to be a timing problem. Can you share your ConfBridge 
configuration?

Re: [asterisk-users] Confbridge for 80 devices

2022-10-20 Thread Jerry Geis 
What is the trick to get "preload => res_timing_dahdi" working ?

I have tried to add to both a CentOS 7 (metal box) and Ubuntu 20.04 (VMware
guest) system
restart asterisk and neither print anything about res_timing_dahdi in the
/var/log/asterisk/messages file.

Both are having issues with around 80 Confbridge items.

timing test on BOTH return the same...
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

I dont think either system is "correctly" using the dahdi timer.

Thoughts ?

So I did the "timing test" got
 timing test
Attempting to test a timer with 50 ticks per second.
Using the 'timerfd' timing module for this test.


in modules I added
[modules]
autoload=yes
preload => res_timing_dahdi.so
preload => res_timing_pthread.so

Re-ran the timing test got the same thing.
Notice it says specifically timerfd - not timing_dahdi or timing_pthread.
System is CentOS 7.

lsmod | grep dahdi
lsmod | grep dahdi
dahdi_transcode14291  1 wctc4xxp
dahdi_voicebus 59241  1 wctdm24xxp
dahdi 228002  9
wctdm24xxp,wcaxx,dahdi_transcode,oct612x,dahdi_voicebus,wcb4xxp,wct4xxp,wcte43x,wcte13xp
crc_ccitt  12707  2 wctdm24xxp,dahdi

Is my timing OK - or not ?

Note /var/log/asterisk/messages says "nothing" about timing even though the
resourse were loaded.

Thoughts ?
