As well, specific ATA settings are required. These settings depend on how the
telephone is connected to the system (ASM, ASM8+, or ATA).
IP phone line configuration
IP telephones have a very similar DN configuration to digital telephones.
There are several models of i-series telephones, and each telephone has a
different number of programmable buttons. Refer to the Nortel i-series
telephone user cards for details.
Proactive Voice Quality Monitoring
The following path indicates where to set PVQM thresholds in Element
Manager:
• Element Manager: Administration > Telephony Metrics > PVQM >
Threshold Settings Panel
PVQM monitors and reports on call quality in process, not just after the end of
the call. This enables more timely and accurate resolution of potential call
quality problems, especially on more lengthy calls. A call quality threshold is
set so that an exception is reported if the quality drops below a configurable
value.
PVQM is fully supported on 1210, 1220, 1230, 1110, 1120E, and 1140E IP
phones and on Phase 2 of the 2000 series IP sets. Phase 1 of the 2000 series
IP sets support only the following PVQM metrics: packet loss, inter arrival
jitter, and round trip delay.
Hot desking IP phone configuration
You can transfer your IP telephony configuration temporarily from one IP
telephone to another using the Hot desking feature. This feature is described
in detail in the Telephone Features User Guide (NN40020-100). You use
FEATURE *999 to enter the feature. To perform Hot desking, you are
prompted for a password, which is specified at the telephone, before you can
complete the task.
Default memory button programming for sets
Button programming allows you to program the buttons on a telephone with
internal and external autodialers, and with programmed feature keys.
Assigned line, Hunt group designator, answer DNs buttons, intercom buttons,
and handsfree buttons cannot be changed through button programming.
These latter features appear in read-only format on the Button Programming
table. During startup, the installer chooses one of the available telephony
template (PBX or DID). Each profile has a default features set that assigns
automatically to the programmable buttons on telephones plugged into the
system, unless you configure different settings in the DN record.
