<p class=MsoNormal>There is a theory that says that jitter buffers should not
be used until the end of the voice path where jitter might be introduced. With
that in mind, and in this scenario, the jitter buffers should reside at the ATA
and media gateway;<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>ATA (SIP UA) <> ASTERISK NATIVE BRIDGE <>
MEDIA GATEWAY (SIP TO TDM)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>That raises a question about the Asterisk Native Bridge; Are
the UDP RTP packets bridged in such a way that out of order packet arrivals between
the ATA and asterisk can still be buffered and corrected at the media gateway,
or are the RTP sequence numbers re-written by the Asterisk native bridge so the
media gateway is now unaware that they are not in the same order as they were initially
transmitted?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Anyone know the answer? Has it been validated with packet
captures, or code review?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks a bunch!<o:p></o:p></p>
