[Freeswitch-users] Internal VM Audio is below acceptable limit

Fri Mar 23 17:51:33 MSK 2012

Hey Peter,

Very interesting, I certainly do not have access to the physical host to do any tweaking for performance values on the virtual machine. What bugs me though is if I pickup the handset attached to an ATA box I do not run into this problem with voicemail. If I had to guess I would have said that this is a problem with softphones and the way they handle audio.

I do have an old PC kicking around that I can stick FS on. I’ll move my conf files over and run a test on a physical machine to see what happens. I did fight against putting FS on the VPS but lost. My concern was network latency not potential performance issues.

Ok – that’s the problem then :)

If you want to make sure everything “just works” – install on real hardware.

If you use the built in tools timer_test and time_test I’m pretty sure it will show you quite bad timing.

It’s not impossible to succeed with a virtual setup, but it will require lots of testing, and usually you need to be in control of the physical host, so it’s possible to tweak some performance values for the virtual machine.

Actually, I believe what he was asking about was the actual server, although the info you provided already does give us some insight into your setup.

Is the freeswitch instance running on virtual or real hardware?

Hey Peter,

Thank for the question. We have a mixture of softphones on computers and
mobiles and handsets connected on a ATA box. It seems that the handsets can
leave VM but the softphones cannot. I would never have thought of grabbing a
handset to test this.
For the office this won't be a problem for too long as we are moving to
phones but we do have the option of working from home and those cases
require softphones to work.

Are you on real hardware, or on a virtual machine?

I have FS up and running with the awesome help of this community. I have a
few minor bugs to workout. Some of my own doing (music on hold) but one that
I can't trackdown or figure out the cause is when someone internally calls
an extension and tries to leave a voice mail the system says something to
the effect that the audio was below acceptable limit, basically it was too
short.
If the person at the extension picks up there is a slight pause and then you
can talk with no issues and the audio sounds great.

If the same extension is called from an outside line and the call goes to VM
there are no problems leaving a message.
