Maintenance Manual

Redial
limit
Enables or disables the redial limit for
this endpoint, and overrides the
corresponding box-wide setting.
The redial limit allows the MCU to stop trying to reconnect a
failed call. When the limit is enabled, the MCU will attempt to
reconnect up to ten times: once immediately after the
connection failure; four times at one minute intervals
thereafter, and once every five minutes for a further five
attempts.
When the redial limit is disabled, the MCU continues retrying -
once every five minutes - after those first ten attempts. It will
do this until the connection is made. If the connection is never
made, the MCU continues retrying until either the conference
or the participant is destroyed.
The redial pattern has an initial delay when the redial behavior
is set to Redial on any disconnection. With that setting, the
MCU does not immediately redial after a deliberate
disconnection - it waits 30 seconds.
DTMF
sequence
The DTMF sequence to send to an
endpoint after it answers the call.
The sequence may be up to 127
characters long and may include digits
0-9 and the following characters: *
(star), # (pound/hash), and , (comma).
The comma represents a two second
pause.
There is always a two second pause
after the call connects, after which
the MCU will send the DTMF tones at a
rate of two per second. You can insert
as many two second pauses as you
need by inserting commas into the
DTMF sequence. Leading and trailing
commas are supported.
This sequence enables the MCU to navigate through an audio
menu. This is useful where a conference on the MCU dials out
to an audio-only conference on an audio bridge.
You can configure the audio bridge as a pre-configured
endpoint (either H.323 or SIP) and specify the DTMF sequence
which will than be used whenever the bridge is added to any
conference. Alternatively, you can add the audio bridge as an
ad hoc participant to an individual conference.
For example, assume you want the MCU to dial out to a PIN-
protected audio conference on an audio bridge. The
conference ID is 555 and the PIN is 888. The audio bridge
requires that you press # after entering the ID and after
entering the PIN. In this example the DTMF sequence could
be: 555#,,888#. The two commas represent a four second
pause which allows the audio bridge's automated menu
system time to process the ID and request the PIN.
Suppress
audio
during
DTMF
Suppresses the audio stream while
initial DTMF connection sequence is
being sent, so that other conference
participants do not hear the audio of
this participant or interactive voice
responders reacting to the tones.
Outgoing only suppresses the audio to
the endpoint while DTMF tones are
sent to the endpoint.
All also suppresses both incoming and
outgoing audio for the participant
while the initial DTMF sequence is
being sent to the endpoint.
This setting is independent of other audio muting
mechanisms. Audio suppression is active for the duration of
the DTMF tone sequence, including any deliberate pauses
(commas in the DTMF sequence).
