I2050Qossvc.exe - Nortel 1110 Fundamentals

•
To prevent improper assignment of these settings, this tab is removed in IP
Softphone Version 2. The 802.1Q p settings are automatically detected.
QoS is otherwise supported in IP Softphone 2050 Version 2 as it was in IP
Softphone 2050 Version 1.
Application thread priorities
Priorities are determined by thread priorities. The i2050QosSvc.exe
application consists of threads, which run the Graphical User Interface
(GUI) and audio threads. Thread priorities increase from the base priority
of the process, as needed. The audio threads boost to high priority, as
recommended by Microsoft, while the GUI maintains a normal priority.
Increasing the process priority implies that the operating system may not
perform properly. This concern restrains the IP Softphone 2050 to use
Windows recommended priorities to avoid an unpredictable degradation
in general OS performance.

i2050QosSvc.exe

i2050QosSvc.exe provides QoS tagging to outgoing 2050 IP packets.
When the IP Softphone 2050 application opens a socket, the i2050QosSvc
software monitors traffic destined for the specified IP address and port.
i2050QosSvc software sets DiffServ QoS priority bits.

Automatic Detection—sends 802.1Q/p packet, which requires a
response from the TPS. If the TPS replies, 802.1Q.p is used. If the TPS
does not reply, the same packet is sent without 802.1Q/p. If the TPS
replies, then 802.1Q/p is not used.
G.711 provides the highest quality (if the network facilities can handle
the packet flow) because there is no compression.
G.729 is ranked best; it has 8:1 compression but no voice activity
detection.
G.711-64 A-law and µlaw: 10-960—10 ms increments
G.729A: 10-960—10 ms frames
G.729AB: 10-960—10 ms frames
