Avaya X330WAN manual PPP VoIP Configuration

Chapter 4 Operational Concepts and Configuration Examples

Note: By default, Avaya IP phones have the DSCP value configured to 46 and do not tag packet priority. To enable such packets to reach the VoIP queue, they should be tagged with a priority of 6. To achieve this, either set the IP phone to Tagging Mode, or use an appropriate DSCP-802.1p mapping in X330WAN. For more information, refer to "Policy" on page 48.

To improve voice quality using cRTP, refer to the “Configuration tip” on page 54.
