Troubleshooting
The information presented here shows how to troubleshoot AudioCodes devices.
DSCP
The phone's Teams application supports DS (Differentiated Services) containing a differentiated
Services Code Point (DSCP) value and an ECN (Explicit Congestion Notification) value, for
monitoring Quality of Service (QoS).
DSCP is part of the IP header that defines the type of routing service to tag outgoing voice
packets originated from the phone. It informs routers that this packet must receive a specific
QoS. Values can be set in decimal (e.g., 184) or hexadecimal (e.g., 0xb8). The default value is
0xb8
(184).
