<DIV><FONT face=Arial size=2>Interesting point from Malik. VoIP.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My initial feeling is even if the routing between
GCC countries through US is totally inefficient from engineering point of view,
but if most of the data IP traffic is really not between the GCC country,
we may not care. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>However, if VoIP is to be a significant service,
then I suspect there may be a lot of VoIP traffic between GCC countries.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In which case, one may pay attention to ITU
recommendation G.114 on One-way Transmission Time (note: not round trip) and its
effect on voice services. It suggests to keep the one way latency to
under 150 ms. 150 - 400 ms is acceptable depending on
application. Anything above 400 ms is not acceptable.</FONT></DIV>
