Introduction

Use the SIP UA Port-Level-Configuration window to configure options at the FXS-port level. The window lists the FXS ports along with the following status information for each port. Until the port is configured, the status for each parameter is "Unavailable."

ParameterDescription
Port-Level-configThe number of the FXS port.
Hook-stateThe current hook-state of the port: onhook, offhook, in-call
Registration-stateThe registration state: unregistered or registered
LicensedThe license status of the port.

To configure the settings for a specific FXS port, click on the arrow to the left of an FXS port number. The window expands to show the options for the selected port.

Use the following table to review information on the configuration options.

ParameterDescription

FXS-Port

A read-only field identifying the number of the FXS port you are configuring.

SIP-Display-Name

Specifies the display name for outbound calling party name purposes.

SIP-User-Name

Identifies the analog phone connected to the FXS port. This value can be either a name or a number that callers use to reach the analog phone. This username is added to the Edge 8300's client list for call routing.

SIP-Authentication-Name

Specifies the name the FXS port uses to authenticate itself if the Enable-SIP-Authentication-Name option is set to False in global configuration.

Password

Specifies the password to authenticate the SIP UA against the softswitch or outbound proxy.

Codec-Preference

Choose a codec type from the Codec Preference drop-down list. The Edge 8300 chooses this codec when offered by the far end regardless of the order of appearance in the SIP SDP.

This selects the codec that is used by all FXS ports for encoding analog data. The codec must be part of the negotiated codec list: G.711 uLaw, G.711 aLaw, G.729, G.728, G.726-16, G.726-24. G.726-32, G.726-40, G723-63, G723-53, G729E, and Global.

Use-Preferred-Codec-OnlySet this option to True to specify that only the preferred codec is used when the FXS places a call. An incoming call is rejected if it does not have the preferred codec.

SIP-User-Domain

Enter a domain in this field to use a value other than the domain configured on the global configuration page.

Tx-Gain-To-FXS

Choose the analog transmit gain for the FXS port. The default setting of 0dB is appropriate for most installations; however, you can adjust the setting to interoperate with user endpoints such as phones, fax, or key systems. Range is -16dB to 16dB, default is 0dB.

Note

If dealing with echo on line, ensure a delta of at least 6DB between the Tx and Rx gain settings.


Rx-Gain-From-FXS

Choose the analog to receive gain for the FXS port. The default setting of 0dB is appropriate for most installations; however, you can adjust the setting to interoperate with user endpoints such as phones, fax, or key systems. Range is -16dB to 16dB, default is 0dB.

Note
If dealing with echo on line, ensure a delta of at least 6DB between the Tx and Rx gain settings.


Enable-Echo-Cancellation

Choose the setting for the echo cancellation. The default setting is True. Range of options are: True and False.

Enable-Call-Waiting

Set this option to True to enable call waiting at the port level. 

Enable-Call-Waiting-CallerId

Set this option to True to enable the call-waiting caller-ID feature at the port level.

Max-Number-Call-Waiting-Tone

Specifies the number of Call Waiting Tones to play. The default value is 2. Range is 2 to 18. 

VAD-Enabled

Choose voice activity detection for the FXS port:

  • Enabled
  • Disabled
  • Global—Allows global VAD settings to be applied at the port level.

Hotline-Number

Enter the number that the port calls automatically when it goes off-hook. If the field is empty, the feature is disabled.

CallerID-Block

Set this option to True to enable endpoint call privacy - user provisioned on the port - in a trusted SIP network (RFC 3325). Caller Identity in the From SIP header is restricted and is instead carried in the P-Preferred-Identity SIP header. If the endpoint does not trust the proxy that it sends request to, do not enable the option.

Disable-Flash-Hook

Set this option to True to disable Flash Hook on the port.
