DiffServe Settings for VoIP Calls
To ensure that priority queuing is set appropriately and voice packets are not droped, the
DiffServe settings on G150 must match those set on Communication Manager and any other
equipment (such as routers) on the network that effect Quality of Service. These settings effect
VoIP calls when the G150 is in both subtending and survivable mode. The following table shows
the configurable fields on the G150 and their corresponding configuration on Communication
Manager:
