8. Click the drop-down arrow for Monitor Modem Tone to select either Enabled or Disabled.
When enabled the module will allow audio monitoring of modem tones during connection in
POTS Codec mode via the phone input. By default, the following phone input monitoring rules
apply when multiple POTS G5 modules are installed in a codec and multiple POTS
connections are dialed.
Module 1
POTS Codec
(Monitor Modem Tone)
POTS Codec
(Monitor Modem Tone)
Analog Phone
Important Notes:
·
Modem tone monitoring will work even if Phone Input Enable is Off via Settings >
Audio > Phone Input > Phone Input Enable [Off].
·
Modem tone monitoring is only enabled during the initial connection training and
negotiation period in POTS Codec mode.
·
The monitoring volume can be adjusted using the codec front panel via Settings >
Audio > Phone Input > Level, or by opening the Inputs panel in the Web-GUI and
adjusting the Phone input volume slider.
9. Country displays the current country setting in the codec. To adjust this setting select Settings
> System > Country.
10. Click Save when configuration is complete.
23.6.2 Configuring POTS Answering
It is possible to store a different POTS Answer Config for each POTS module installed in the
codec. POTS answering can be configured to suit:
·
The type of call being made, e.g. Tieline (with Tieline Session Data) versus non-Tieline
(Sessionless).
·
Expected dialing behaviors and encoding, e.g. whether audio streams use Route tags and
which algorithm is used.
If you answer a call from a non-Tieline codec you will need to create an answering "Config" to
determine which module in the codec will answer the call and the settings used when connecting.
Important Notes:
·
POTS Answer Config settings are applied to POTS Codec connections and not
Analog Phone connections.
·
When receiving a call from a Tieline codec with session data enabled (i.e. not
Sessionless), the algorithm setting from the dialing codec overrides the setting in the
POTS Answer Config menu.
