Introduction
Use the following parameters SIP Gateway Port-Level-Configuration window to configure options at the specific FXO-port level. The window lists the FXO ports along with the following status information for each port.
Parameter | Description |
---|---|
Port-Level |
...
-config | The number of the FXO port. |
Admin-State | The administrative state of the port. Until it is configured, the port appears as disabled. Once it is configured, it is enabled and shows a green check mark. |
Call-State | Until it is configured, the call-state is "unavailable." Once it is enabled, the call-state appears as onhook, offhook, or in-call. |
To configure the settings for a specific FXO port, click on the arrow to the left of an FXO port number. The window expands to show the options for the selected port.
Use the following table to review information on the configuration options.
Parameter | Description |
---|---|
FXO-Port READ-ONLY VALUE: 0 or 1 | A read-only field identifying the number of the FXS port you are configuring. |
Enable-FXO-Port | Select the Enable FXO port dropdown Set this option to True toenable the FXO/Line port for incoming and outgoing calls.When this field is not checked, the FXO/Line port is disabled. The options are True and False. |
Two-Stage-Dialing-From-IP | Select the Enable InBound (from IP network) two-stage dialing dropdown to allow Set this option to True toenable two-stage dialing for incoming calls from the IP network. The options are True and False. Default is False |
Two-Stage-Dialing-From-PSTN | Select Enable InBound (from PSTN) two-stage dialing to allow Set this option to True to enable two-stage dialing for incoming calls from the PSTN. Provides dial tone when a call is answered. The caller can then dial an extension to further complete the call or hang up. The options are True and False. Default is False. |
Forward-To | If the Enable InBound (from PSTN) two-stage dialing is not selectedTwo-Stage-Dialing-From-PSTN is not enabled, enter a name or number in the Forward to field to which you want to automatically forward incoming calls from the PSTN to this name or number. |
PSTN-Incoming-Accept-Method | Provides Select which type of condition enables a connection for a call calls from the PSTN to the IP under two conditionsnetwork: If callerCallerID Detection - connect a call if caller ID is detected , then a call connects. WhenRing Detected Counts - connect the call to IP using a simple ring detect , connect the call to IP. The options are CallerID Detection and Ring Detected Counts. Default is CallerID Detection. |
PSTN-Accept-Ring-Counts | Provide the PSTN Accept Ring Counts value to define If Ring Detected Counts is selected as the PSTN incoming accept method, enter the number of rings to connect detect before connecting to the IP . This value applies when the ring is selected as an accepted method. The network. The range is 2 to 8. |
Tx-Gain | Choose the Analog Transmit gain . Control to control the gain of the media signal coming to FXO from the IP side. The options are in the following list (Range is -16dB to 16dB. Default is 0db). Note: In cases where the default value does not optimize echo cancellation, adjust the gain with from -6DB in steps to -10DB until the echo is gone. |
Rx-Gain | Choose the Analog Receive gain . Control to control the gain of the media signal coming to FXO from the PSTN side. Based on the line conditions, sometimes the level of the DTMF signal sometimes needs to be boosted to make DTMF detection more reliable. Range is -16dB to 16dB. Default is 0dB. |
