Quality of Service: DiffServ (Differentiated Services)
DiffServ (Differentiated Services) ist a method that organizes IP data
packets for transmission or forwarding in service classes. A higher service
class means that the data packets are treated preferentially (e. g. VoIP voice
packets for a better voice quality).
Requirements:
•
Available and enabled support for DiffServ in all active network compo-
nents (e. g. hubs, switches, router, etc)
Note:
DiffServ is not supported by all VoIP providers. When used in a
standard VoIP account, these settings may not be applied in some situa-
tions.
The activation of DiffServ requires a reboot of the telephone. For VoIP
calls, the service class in accordance with RFC 4595 is set.
