<DIV><FONT face=Arial color=#000000 size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>we have a 5.x cluster with several gateways. We
have implemented QoS in the LAN (classification, marking and scheduling). The
CallManager instructs the IP phones to use CoS marking for signaling (SCP) and
voice (RTP). For a call to the PSTN, the path IP Phone->Gateway is QoS aware,
but what happens in the other sense?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We have some MGCP and H323 gateways. The switch
ports where the gateways are connected are trusted, but does the H323, MGCP and
RTP traffic originated in these gateways with destination the CCM or an IP Phone
for an external call have any QoS mark?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance,</FONT></DIV>
