Description (partial)

++ On ASR 1001-X running IOS-XE ver 16.9.4 and is facing the following issue:

++ If we have dial-peer level QOS configured, DSCP marking is applied to regular SIP signalling for calls, but its not applied to Options Ping /  NOTIFY, and 200OK and ACK.
++ On DP level, DSCP marked as CS3, but when CUBE sending options ping, its marking DSCP as AF31, not CS3, and even some of the signalling like (NOTIFY, and 200OK and ACK) are using CS0, not CS3.

++ When using DP level DSCP marking.
