[Freeswitch-users] problem with voice quality

[joy this]

Dear all:



        The scenario is that, when I use 3CX (PCMA) to call XLite, 3CX will
hear loud noise but XLite is fine. And I found that it would only happen
when XLite supports PCMA and PCMU simultaneously. If XLite only support
PCMA, everything is fine.

Maybe it is because of the old version of Freeswitch, I download the latest
version yesterday and re-test. The result is that 3CX hear nothing instead
of noise. I use Wireshark to survey packages, and the server does not
transfer UDP packages to 3CX. I check the log file, it is as below.



-----3CX hears nothing-----

-----log end-----



When XLite only supports PCMA, it would be an additional log:

2011-02-24 20:16:06.661625 [INFO] switch_rtp.c:2968 Auto Changing port from
192.168.1.1:51508 to 114.24.x.x:51508

        And I test it again by using a public VoIP server (
sip.lowratevoip.com), there is no noise or silence situation, everything is
fine.

        Does XLite get bugs? Why the public server can deal with the
situation? Could anyone help me?


Sincerely yours,

thisjoy.
