Network requirements
Note:
Priority 0 is a higher priority than Priority 1.
Network audio quality
You can monitor network audio performance on the 9600 Series IP Deskphones while on a call.
You can view this information on the Network Information screen. You can view the Network
Information screen on most 9600 Series IP Deskphones button-based deskphones from the
Avaya (A) Menu and select the Network Information option directly if available. You can also
select Phone Settings, then select the Network Information option. On touch screen
deskphones such as 9621G, 9641G, and 9641GS, you can gain access to the Home screen, then
select Settings, then Network Information.
While on a call, you can view the network audio quality parameters in real-time. See the following
table for the various parameters that you can view:

Internal microphone
Internal speaker
The implication for LAN administration depends on the values the deskphone user reports and the
topology, loading, and QoS administration for the LAN. This information gives the administrator an
idea of how network conditions affect the audio quality of the current call. Avaya assumes you
have more detailed tools available for LAN troubleshooting.
IP address list and station number portability
You can specify IP address lists on the 9600 Series IP Deskphones . On startup or on restart, the
phone attempts to establish communication with these various network elements in turn. The
phone starts with the first address on the respective list. If the call server denies communication
with the phone or the session times out, the phone continues to the next address on the
appropriate list and tries that IP address. The phone does not report failure unless all addresses
on a specified list fail, improving the reliability of IP telephony.

Possible values
G.711, G.722, G.726, or G.729.
No call. The system counts late and out-of-sequence packets as lost if
the packets are discarded. The system does not count the packets as
lost until a subsequent packet is received and the loss confirmed by the
RTP sequence number.
No data or an integer number of milliseconds. The number reflects the
amount of delay in received audio packets, and includes any potential
delay associated with the codec.
No data or an integer number of milliseconds. The number is half the
value RTCP or SRTCP computes for the round-trip delay.
No data or an integer number of milliseconds reporting the average
delay that is introduced by the jitter buffer of the phone.
The system specifies whether internal microphone is on or off.
The system specifies whether internal speaker is on or off.
