    Hi,

    I have a problem of speed of sound with IVR on elastix 1.5.2.

    I done the installation on several linux computers with or without vmware, with or without grub options
    .

    All time I have the same problem, the IVR cannot give a good speed voice. Even voices installed with elastix !

    The unmodified voice file I used is a
    First, I tried to change the format of my voice file with sox

    So the voice is too slow.

    Second, I tried to change the speed of my file with sox

    The speed seems to be good but the voice is too bad.

    Can you help me to solve my problem (or elastix problem) ?

    Thx

    Need more information, as in what hardware spec's are you running and also codecs in use.

    There is a custom kernel optimized for vmware that should work fine:
    Have a look here:

    Also you can try VirtualBox, I think it doesn't have those choppy sound problems.

    I don't test this optimization (I don't find it before). I'll try it.

    But it isn't enough. I have the problem with vmware computers and with
    a physical computer to.

    My computers are :

    1 - HP dual core Intel(R) Xeon(R) CPU 3040 @ 1.86GHz 1.5 Go of RAM with zen 5.
    2 kernel 2.6.21-smp with vmware 1.0.8

    2 - DELL dual core Intel(R) Xeon(R) CPU 3040 @ 1.86GHz 1.5 Go of RAM with slac
    kware 12.2 kernel 2.6.27-smp with vmware 2.0.1 (and 2.0.0 before)

    3 - Intel server Intel(R) Pentium(R) Dual CPU E2160 @ 1.80GHz 3 Go of RAM wi
    th
    • ONLY
    elastix (ie a physical computer).

    The trunk part is :

    host=keyyo.net
    username=339XXX
    secret=MySecret
    type=peer
    context=from-trunk
    insecure=invite
    qualify=800

    So in computer 1 and 2 with zen 5.2 and Slackware 12.2 you have the same sound issues when you install asterisk inside the vmware?
    This is weird. You shouldn't have this problem in a clean Elastix installation.
    Maybe the problem is in your phones?
    Try to reinstall.

    Thx ramoncio,

    I test http://pbxinaflash.com/vm/ on a vmware server ad it is running !

    So, I done the same test on the physical computer and ... IT IS RUNNING fine !!!!

    So the problem is with the default linux kernel of elastix (Don't be afraid, the problem can be found in the trixbox distribution too. I test it and stop to use it because keyyo).

    Just a tone down : there are lot of
    (wct4xxp, wcte12xp, wct1xxp, wctdm24xxp, wcfxo, wctdm, wcb4xxp, wctc4xxp, xpp_usb, rxt1, r1t1 and rcbfx)
    with a fatal module dahdi not found ???

    (I can just test with on vmware, the physical computer is not in my office)

    Great thx.

    after a few restarts the problem is back, chopy/ slow sound.
    it seems there is a problem with the DAHDI timing.
    any idea?
