Adjusts the voice path volume.
• Rx is a gain level for signals transmitted by FXS
• Tx is a gain level for signals received by FXS.
Default = 0dB for both parameters. Loudest volume: +6dB Lowest volume: -6dB.
User can adjust volume of call using the Rx gain level parameter and the Tx gain level parameter located on the FXS
Gain
port configuration page.
If call volume is too low when using the FXS port (ie. the ATA is at user site), adjust volume using the Rx gain level
parameter under the FXS port configuration page.
If voice volume is too low at the other end, user may increase the far end volume using the Tx gain level parameter
under the FXS port configuration PAGE.

Ring Power
OnHOOK DC
This feature is used to adjust DC feed current.
Feed Current
This feature allows users to customize the count of RFC2833 events.
RFC2833 Events
The Valid Value Range is between 2 and 10 , if it is set to 0 , it means continuous RFC2833 events are activated
Count
Default is 8.
RFC2833 End
This feature allows users to customize the count of RFC2833 end events. Default is 3.
Events Count
Customizes the Ring Tone 1 to 3 with associate caller ID: when selected, if caller ID is configured, then the device
will ONLY use this ring tone when the incoming call is from the Caller ID. System Ring Tone is used for all other
calls. When selected but no Caller ID is configured, the selected ring tone will be used for all incoming calls using the
FXS port. Distinctive ring tones can be configured not only for matching a whole number, but also for matching
prefixes. In this case the symbol "x+" will be used.
Distinctive Ring For example: if configured as 617x+, Ring Tone 1 will be used in case of call arrived from the area code 617. Any
other incoming call will ring using cadence defined in parameter System Ring Cadence located under Advanced
Tone
Settings Configuration page.
Note: If server supports Alert-Info header and standard ring tone set (Bellcore) or distinctive ring tone 1-10 is
specified, then the ring tone in the Alert-Info header from server will be used. Bellcore rings and tones are
independent from custom ring tones.
The custom ring tones can also be specified by alert-info header, for example Alert-Info: <127.0.0.1>; info=ring5
Configures the ring tone cadence preferences. User has 10 choices.
Ring tones
The configuration, completed in Distinctive Ring Tones block in the same page, applies to ring tones cadences
configured here.
Distinctive Call Customizes the Call Waiting Tone 1 to 10 with associate caller ID: when selected, if caller ID is configured, then the
Waiting Tone device will ONLY use this call waiting tone when the incoming call waiting is from the Caller ID. When selected but
no Caller ID is configured, the selected call waiting tone will be used for all incoming waiting calls using the FXS
port. Distinctive Call Waiting Tones can be configured not only for matching a whole number, but also for matching
prefixes. In this case symbol "x+" will be used.
