QoS for SCN which ports?

[KatzEye1]

hi guys, i thought the only ports we needed to identify on QoS for SCN traffic would be the RTP session ports, which can be taken from the telephony tab in 3.2 etc but we still get back call quality once the net line gets congested, soon as all other data traffic ends the call goes back to very good. i've set to g.729.

i'm sure there are other ports/traffic at work here between the 2 IPOs once a call is established, i've looked at the faq and included the other SCN BLF ports...any others i should be aware of?

many thx!

sorry i meant RTP ports from gatekeeper tab not telephony

If you're prioritizing based on port then yes you want to prioritize the ports in the RTP range.

Why not use DSCP markings?
