The Advanced Parameters settings, shown as follows, are accessed by clicking on the Advanced Parameters item in the lefthand menu and are a collection of AudiCodes-specific settings.
The following configuration options are available on this page (click on Show Advanced Settings to reveal all options):
- Secure SIP Calls: If this is enabled, gateways will only accept SIP calls from IP addresses listed below. The default is disabled (unchecked)
- Accepted IP Addresses: They are used in conjunction with the above setting. It is a space-separated list of IP addresses from which gateway will accept the calls. It is taken into account only if Secure SIP Calls is enabled. The default is the IP address provided for the PBX during install.
- Digit Delivery to Telephony Port: This setting enables a digit string to be played to the port at the far end, after off-hook. The default is disabled (unchecked).
- Digit Delivery to IP: This setting enables a digit string to be played to the port at the far end, after off-hook. The default is disabled (unchecked).
- DID Wink Support: When this is enabled, the gateway can connect to EIA/TIA 464B Loop Start DID lines. Both generation and detection are supported. The default setting is disabled (unchecked).
- Enable Call Disconnect on Polarity Reversal: If this is checked, enables port disconnect (on-hook) based on polarity reversal. Some POTS providers will reverse the polarity of the analog phone line to signal disconnection to a PBX. The default is disabled (unchecked). Enable Call Disconnect on Current Drop: If this is set to 1, enables port disconnect (on-hook) based on current drop. The default setting is disabled (0).
- Enable Call Disconnect on Broken Connection: If this is checked, the call is released if the gateway stops receiving RTP for a period of time. The default is enabled (checked).
- Broken Connection Timeout (10msec): The amount of time for which RTP is not received, before the call is cleared. In 10 ms steps, the default is 500, 10 ms steps (5 seconds).
- Enable Call Disconnect on Far End Silence: If this checked, enables disconnection of call based on silence. The default is disabled (unchecked).
- Silence Period for Disconnect: The detection period, in seconds, before the call is released based on silence. The default is 120 seconds.
- Silence Detection Method: This setting can be set to “None” (silence detection option is disabled), “Packets Count” (according to packet count), “Voice/Energy Detectors” (according to energy and voice detectors (default)) or “All” (according to packet count and energy / voice detectors).
- Silence Threshold: The threshold of packet count, in percentage, below which is considered as silence. The default setting is 8 packets.
- Detail Level in Debug Log: The detail level of the log messages sent to syslog server. Default is 0 (off), max is 5 (full).
- CDR Server IP Address: An optional separate syslog server to collect CDRs only. If null and CDR is enabled, the output is mixed with the log messages and is routed to the syslog server IP. (Default: 0.0.0.0)
- CDR Report Level: This can be set to “None”, (Call Detail Recording or CDR information isn’t sent to the Syslog server, which is the default value), “End Call” (CDR information is sent to the Syslog server at the end of each Call) and, “Start & End Call” (CDR information is sent to the Syslog server at the start and at the end of each Call).
- Port Busy-Out Method : If there is a network-side failure on the gateway, the POTS interfaces can be set to busy. If this is checked, telephony ports are busied out (special tone) in case of LAN failure or proxy communication failure. The default is disabled (unchecked).
- Delay After Reset [sec]: Amount of time delay before answering calls after gateway reset. The default is 7 seconds.
- Max Number of Active Calls: This is the maximum number of active calls the PBX can process. It should be set to the number of PSTN lines active.
- Max Call Duration [min]: This is the maximum duration of a phone call. The default is 0, which means no maximum.
- Enable LAN Watchdog: When LAN Watchdog is enabled, the gateway’s overall communication integrity is checked periodically. If no communication for about 3 minutes is detected, the gateway performs a self test. If the self test succeeds, the problem is logical link down (for example, Ethernet cable disconnected on the switch side), and the “Busy Out” mechanism is activated if enabled (EnableBusyOut = 1). Lifeline is activated if enabled. If the self test fails, the gateway restarts to overcome an internal fatal communication error (default: unchecked).
- Enable SAS: This setting is to enable/disable Stand-Alone Survivability (SAS) (default: unchecked). • SAS Registration Time: This is the time after which SAS is enabled (default: 20 seconds).
- SAS Local SIP UDP port: This is the UDP Port for SAS SIP signaling (default: 5080).
- SAS Local SIP TCP port: This is the TCP Port for SAS SIP signaling (default: 5080).
- SAS Local SIP TLS port: This is the TLS Port for SAS SIP signaling (default: 5081).
- SAS Default Gateway: This is the SAS Default Gateway IP address (default blank).
- SAS Short Number Length: This is the SAS short number length.
