Hi, I solved this issue. the reason is because of the different port
number between the the one in SDP and the one in real RTP stream. This
is very nice feature. <br>

Hi, I got a weird issue when I dialed an extension and listen to a recorded voice mail greeting message. <br>
After playing a couple of time of the greeting, the FS printed the warning of "sample rate not matching", then <br>
send the audio to a different remote RTP port. See the log below,<br>

<br>
the original codec is wideband 16kHz Speex and the wireshark shows that the FS used the same codec. I used FS 1.04 in fedora 8.<br>
I have two questions here,<br>
(1) why does FS report <span style="font-style: italic; text-decoration: underline;"><span style="text-decoration: underline;"><span style="font-style: italic;">"</span></span></span><span style="text-decoration: underline;"><span style="text-decoration: underline;"></span></span>Sample rate doesn't match"? is it a bug or configuration issue?<br>
(2) Why does FS change the RTP port ? how to fix it? <br>
<br>
Thanks,<br>
<br>
Regards,<br>
