[cisco-voip] QoS on VoIP Gateways

[Ryan Ratliff]

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.

Subject: [cisco-voip] QoS on VoIP Gateways


Hello,
 
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?
 
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?
 
Thanks in advance,
 
Ruben
