Operating the system
Selecting the call type
Definition
The phone connection can use one of the following call types:
• Standard Voice, which is a low-tariff voice connection compressed to
4.0 kbps,
• 3.1 kHz Audio, which is a high quality connection used for Premium Voice,
G.3 fax or analog modem,
• UDI or RDI (only on ISDN interface), which is used for G4 fax or data.
In the web interface you can set up which type of connection to use by default
when you make or receive a call from the Phone/Fax or ISDN interface or from
an IP handset connected to the LAN interface.
When connecting a fax or a modem to the Phone/Fax interface you must use
3.1 kHz Audio.
Example: If you always have a fax connected to the same Phone/Fax
interface you can set this interface to 3.1 kHz Audio only. This will
mean that if an incoming Standard Voice call is received, this
Phone/Fax interface will not ring.
When connecting a G4 fax or a modem to the ISDN interface in the
TracPhone FB500 system you must use UDI.
Selecting the default outgoing call type
To select the default call type for outgoing calls, do as follows:
• ISDN. Select the call type in the web interface under SETTINGS > ISDN.
For further information, see Configuring the ISDN interface on page 92.
• Phone/Fax. Select the call type for each port in the web interface under
SETTINGS > Phone/Fax.
Note
UDI and RDI are not available with the TracPhone FB250 system, so
you cannot connect a G4 fax machine nor a modem to the ISDN
interface on the TracPhone FB250 system.
