default dscp values for media (both on mgcp and h323) are what you are
expecting. If in doubt set them manually either by command (if you are
trusting the router) or via remarking if you are not trusting the
endpoint.</FONT></SPAN></DIV>

color=#0000ff size=2>Yes the signalling traffic should be marked just like any
other voip signalling. You can set the specific values for
dscp for both H.323 and MGCP with commands on the
gateway.</FONT></SPAN></DIV>

<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>
