[asterisk-users] Running on virtual machine and audio not intelligable
Hi All, Running asterisk 11.25.3, the /proc/cpuinfo says Intel(R) Xeon(R) CPU X5675 @ 3.07GHz lsmod | grep dahdi gives dahdi_transcode 16384 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 -------------- next part -------------- An HTML attachment was scrubbed...

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

>why load or even install dahdi if no cards are used?I thought dahdi was needed for a timing source. Doesn't ConfBridge need a timing source?

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. Richard -------------- next part -------------- An HTML attachment was scrubbed...
