dscp in voip dial-peer

[i.fouraki]

Hi,

In voip dial-peer configuration we can set a dscp value for media and for signaling. My question is what kind of signaling do we mark? Is it H225? If we have MGCP or SIP gateway, is this signaling included or we have to mark it excplicitly (outside dial-peer) with access-lists/class-maps, etc?

Thanks,

Yanna

With dsco both H225 and H245 are marked. For MGCP you will need to configure it in the global config:

mgcp ip qos dscp cs5 media

mgcp ip qos dscp cs3 signaling

The followinbg couple of URLs might be helpful.
