Viewing IP Connectivity

You can view on-line, read-only network diagnostic connectivity information on destination IP addresses configured in the Tel-to-IP Routing table (see Configuring Tel-to-IP Routing Rules).

The table is applicable only to the Gateway application.

➢ To view IP connectivity status:
1. Enable alternative Tel-to-IP routing that is triggered by connectivity loss with destination. This is done by configuring the AltRoutingTel2IPEnable parameter to Enable or Status Only. For more information, see Alternative Tel-to-IP Routing Based on IP Connectivity.
2. Open the IP Connectivity table (Monitor menu > Monitor tab > VoIP Status folder > IP Connectivity).

IP Connectivity Table Description

Column Name

Description

IP Address

Displays the destination IP address, which can be one of the following:

■ Destination IP address as configured in the Tel-to-IP Routing table.
■ Destination IP address resolved from the host name (FQDN) as configured in the Tel-to-IP Routing table.

Host Name

Displays the host name (or IP address) as configured in the Tel-to-IP Routing table.

Connectivity Method

Displays the method according to which the destination IP address is queried periodically by the device to check keep-alive connectivity status (SIP OPTIONS request). To configure the keep-alive mechanism, see IP Destinations Connectivity Feature.

Connectivity Status

Displays the connectivity status with the destination:

■ "OK": Remote side responds to periodic connectivity queries.
■ "Lost": Remote side didn't respond for a short period.
■ "Fail": Remote side doesn't respond.
■ "Init": Connectivity queries not started (e.g., IP address not resolved).
■ "Disable": Connectivity option is disabled (i.e., [AltRoutingTel2IPMode] parameter is configured to None or QoS). For more information, see Alternative Tel-to-IP Routing Based on IP Connectivity.

Quality Status

Displays the QoS (according to packet loss and delay) of the destination:

■ "Unknown": Recent quality information isn't available.
■ "OK"
■ "Poor"

Note:

■ The parameter is applicable only if the parameter 'Tel-to-IP Alt Routing Mode' is configured to QoS or Both.
■ The parameter is reset if two minutes elapse without a call to the destination.

Quality Info

Displays QoS information: delay and packet loss, calculated according to previous calls.

Note:

■ The parameter is applicable only if the parameter 'Tel-to-IP Alt Routing Mode' is configured to QoS or Both.
■ The parameter is reset if two minutes elapse without a call to the destination.

DNS Status

DNS status:

■ "DNS Disable"
■ "DNS Resolved"
■ "DNS Unresolved"
