Explanation

Summary

The RxType and the TxType statistics show the codec that is being
used for a conversation between this conference phone and the other
device. The values of these statistics should match. If they do not, verify
that the other device can handle the codec conversation or that a
transcoder is in place to handle the service.

See the

“

Call Statistics screen

”

section for information about displaying

these statistics.

Codec mismatch between the
conference phone and another
device

When you are on a call that requires keypad input, if you press the keys
too quickly, some of them might not be recognized.

Dual-Tone Multi-Frequency
(DTMF) delay

Check that the ringer setting is not

“

Ringer Off.

”

Check the volume

level.

conference phone does not ring

A loopback condition can occur when the following conditions are met:

•

The conference phone receives power from an external power
supply

•

The conference phone is powered down (the power supply is
disconnected)

In this case, the switch port on the conference phone can become
disabled and the following message will appear in the switch console
log:

HALF_DUX_COLLISION_EXCEED_THRESHOLD

To resolve this problem, re-enable the port from the switch.

Loopback condition

If you are powering your conference phone through the network
connection, you must be careful if you decide to unplug the conference
phone network connection and plug the cable into a desktop computer.

The computer

’

s network card cannot receive power through

the network connection; if power comes through the
connection, the network card can be destroyed. To protect
a network card, wait 10 seconds or longer after unplugging
the cable from the conference phone before plugging it into
a computer. This delay gives the switch enough time to
recognize that there is no longer a conference phone on the
line and to stop providing power to the cable.

Caution

Moving a network connection from
the conference phone to a
workstation

Check that all connections are secure and in place. Make sure all
connections are correct.

No dial tone

Check to make sure that the conference phone has power. Make sure
that the power supply unit is plugged in.

No LCD screen display
