[Freeswitch-users] Questions of packages loss

[joy this]

    I have some tests for the problem that the voice keeps off and on during
the call. I use Wireshark to check the package flow on the caller, callee,
and FS sides. The network structure:
caller(PCMA)---(Wi-Fi)--->WAN--->FS--->callee(PCMA). FS and the callee are
under the same router. The result is: The caller sends 2688 packages to FS,
and FS receives 2687 packages. Then FS sends only 2380 packages to the
callee, and the callee receives 2380 packages. There is about 11.4% package
loss in FS, and the callee hears incomplete voice.

    I have some questions:

    1. I guess FS drops packages from the caller because these packages
arrived too late. Is it reasonable? If not, what is the reason?

    2. I want to check if FS drops packages because of the late arrival.
Could you tell me the packages flow in the source code?

    3. I set the jitterbuffer_msec from 10 to 10000, but it seems not
effective. Wouldn’t the jitterbuffer_msec affect the result?


Sincerely yours,

 thisjoy.
