<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">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 size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">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>
