Description
ShoreTel 9 extends the DiffServ/ToS setting to all voicemail, workgroup, account code
collection (ACC), or contact center calls. One setting applies to all ShoreTel servers in a
ShoreTel system.
ShoreTel 9 also introduces DiffServ/ToS marking for video IP packets. The default value for
the Video DiffServ/ToS Byte is 0, indicating that priority is not defined for Video packets.
Changing the Video QoS setting does not affect video sessions in progress. The updated
value is applied to new video sessions. Call Manager recognizes the change without being
restarted.
Implementation
Voice Packet Marking
The Director Call Control panel provides an option to configure DiffSrv/ToS setting for
Voice calls, as shown in Figure 39. All ShoreTel servers need to be rebooted to enable the
new setting. This parameter configures DiffServ/ToS for voicemail, workgroup, account
code collection (ACC), and contact center calls.
This panel is not altered by the Voice Packet Marking capability change.
Video Packet Marking
The Director Call Control panel is modified to provide a video packet DiffSrv/ToS
configuration options, as shown in Figure 39. Changing this setting does not affect active
video sessions. New video sessions will use the updated value. Call Manager recognizes the
new value without being restarted.
The default value for the Video DiffServ/ToS Byte is 0, which defines no priority for Video.
