why stick with version 11 ? upgrade to 13 is a starting solution.

DAHDI is required for MeetMe to do the audio mixing.  ConfBridge does not
need DAHDI since
it does its own mixing in Asterisk.

As for timing sources you have several to choose from of which DAHDI is one
of them.  See
menuselect res_timing_xxx modules.  Timing is really only needed when
playing back sound
prompts when nothing is being received.

I thought dahdi was needed for a timing source. Doesn't ConfBridge need a
timing source?

why load or even install dahdi if no cards are used?

[asterisk-users] Running on virtual machine and audio not intelligable

[Jerry Geis]

Hi All,
Running asterisk 11.25.3, the /proc/cpuinfo says
Intel(R) Xeon(R) CPU   X5675  @ 3.07GHz

lsmod | grep dahdi gives
dahdi_transcode16384  1 wctc4xxp
dahdi_voicebus 61440  2 wctdm24xxp,wcte12xp
dahdi 225280  11
wctdm24xxp,wcfxo,wctdm,dahdi_transcode,oct612x
dahdi_voicebus,wcb4xxp,wct1xxp,wct4xxp,wcte11xp,wcte12xp
crc_ccitt  16384  2 wctdm24xxp,dahdi

There are no cards in the VM - just the CentOS 7.4 operating system. I'm
actually running 4.4.92 from elrepo as the kernel.

I am using the confbridge with about 100 devices in the "one way"
conference and the audio is not intelligible. Sending audio to a single
endpoint is fine.

dahdi_test running when nothing is happening is 99.8 running with the ALL
100 units in conf is about 99.6.

What can I do do get audio where it needs to be ?  I believe the
environment is VMware.

Thanks,

Jerry
