Some RTP packets will be dropped because they either arrive before the signalling starts the media (on 18x or 200), or they arrive after the hangup.<br><br>How long was the call you made? 2380 suggests under a minute? Try a much longer call and see whether you're still seeing the same amount of loss.<br>

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. </span></p>

have some questions:</span></p>
<p class="MsoNormal"><span lang="EN-US"> 1. I guess FS drops packages from the
caller because these packages arrived too late. Is it reasonable? If not, what
is the reason?</span></p>
<p class="MsoNormal">
</p><p class="MsoNormal"><span lang="EN-US"> 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?</span></p>
<p class="MsoNormal"><span lang="EN-US"> 3. I set the jitterbuffer_msec from 10 to
10000, but it seems not effective. Wouldn’t the jitterbuffer_msec affect the
result?</span></p><p class="MsoNormal"><br><span lang="EN-US"></span></p><p style="text-align: right;" class="MsoNormal"><span lang="EN-US">Sincerely yours,<br></span></p>
