ENA Amplifiers in SIP mode

This article describes the configuration settings available for a Exigo Network Amplifier (ENA) in SIP mode. The ENA Amplifiers are configured through their web interface.

Software requirements

Minimum Software requirement

  • ENA Amplifier: 5.1.3.0

Main

Information

  • Log In to the amplifier
  • The Information page will now be displayed, showing the amplifier configuration and status.
The Information page


Note icon To find the IP address of the amplifier, use the Menu Selection Knob on the front of the amplifier, and navigate to Information > Network.


Main Settings

  • Click Station Main > Main Settings to access the page for configuring Station Mode and IP parameters.
The Main Settings page


Station Mode: Select the SIP radio-button.

Preferred Internet Protocol: Select either IPV4 or IPV6.

IP Settings:

  • DHCP – Select this option if the IP station shall receive IP Settings from a DHCP server.
  • Static IP – Select this option if the IP station shall use a static IP address. Enter values for:
- IP-address
- Subnet-mask
- Gateway
- DNS Server 1 (option for network administration)
- DNS Server 2 (option for network administration)
- Hostname (option for network administration)
  • Disable Reset to Factory default settings using frontboard and I/O: If enabled, factory reset will only be possible from the web interface. This is disabled by default.
  • Enable RSTP: RSTP is only required when using redundant networking

Click Save followed by Apply to apply the new configuration settings.

Recovery

Commands

The Recovery page


  • Full reboot: Perform a full Linux reboot. No configuration is lost
  • Partial reboot: Perform a restart of the intercom application. No configuration is lost
  • Factory reset: Set all parameters to Factory Default values. The amplifier will get static IP Address 169.254.1.100.
  • Factory reset with DHCP: Set all parameters to Factory Default values. The amplifier will get IP Address from DHCP server. If no DHCP server in the network, it will get a random 169.254.x.x IP address.

Preferences

Select SIP Account -> Account/Call to access the page for configuring the SIP Account Settings.

The Account/Call Settings page


Amplifier Settings
  • Name: Enter a name for the amplifier.
Channel 1/2 Account Settings
  • Name: Enter a name that will be shown on the display at the remote party.
  • Number (SIP ID): This is the identification of the station in the SIP domain, i.e. the phone number for the station. This parameter is mandatory. Enter the SIP ID in integers according to the SIP account on the SIP domain server.
  • Server Domain (SIP): The IP address of the SIP Server. This can be either an IP address in regular dot notation or a hostname.
  • Backup Domain (SIP): This is the secondary (or fallback) domain. If the station loses connection to the primary SIP domain, it will switch over to the secondary one. This can be either an IP address in regular dot notation or hostname.

  • Suspend Monitoring Options (only available when Monitor Mode is Continuous)
    • When Suspended Monitoring is enabled, the amplifier will suspend the monitoring signal when there is a call on the channel to avoid false alerts and maintain audio quality.
  • LET (only available when LET Monitoring is enabled)
    • 10 LETs per channel can be added
    • Failed Counter How many times LET should fail before error is reported
  • Calibration Info (only available when channel monitoring is enabled, configured and saved)

    • Reset Calibration (3 seconds timeout) will reset channel calibration
    • Measure (60 second timeout, only available if Monitor Mode is Manual and channel is successfully calibrated) will manual monitor channel for 60 seconds and report any faults detected


IO Monitoring

The ENA amplifier offers monitoring of the outputs and the inputs:

  • RCOs

RCO is not supported for ENA amplifiers in SIP.

  • RCIs
    • RCI Config allows configuring the thresholds for when the RCI triggers. An RCI has an open voltage of 10V across the terminals. A resistor network is needed to ensure that RCI's can be monitored properly.
    • Monitor RCI enables monitoring of RCI.
    • Not Connected - When the voltage on the pin is higher than this threshold, it's set as Not Connected.
    • Not Pressed - Low threshold for the RCI to be considered not pressed.
    • Pressed - High threshold for the RCI to be considered pressed.
