Testing SIP Signaling Calls

A simulated endpoint can be configured on the device to test SIP signaling of calls between
it and a remote destination. This feature is useful in that it can remotely verify SIP message
flow without involving the remote end side in the debug process. The SIP test call
simulates the SIP signaling process - call setup, SIP 1xx responses, through to completing
the SIP transaction with a 200 OK.
The test call sends Syslog messages to a Syslog server, showing the SIP message flow,
tone signals (e.g., DTMF), termination reasons, as well as voice quality statistics and
thresholds (e.g., MOS).

Configuring Test Call Endpoints

The Test Call table lets you test the SIP signaling (setup and registration) and media
(DTMF signals) of calls between a simulated phone on the device and a remote endpoint.
These tests involve both incoming and outgoing calls, where the test endpoint can be
configured as the caller or called party. Test calls can be dialed automatically at a user-
defined interval and/or manually when required. The simulated phone and remote
endpoints are defined as SIP URIs (user@host) and the remote destination can be defined
as an IP Group, IP address, or according to an Outbound IP Routing rule. You can also
enable automatic registration of the endpoint.
When a SIP test call is initiated, the device generates a SIP INVITE towards the remote
endpoint (e.g., a SIP proxy server or softswitch). It simulates the SIP call setup process,
managing SIP 1xx responses and completing the SIP transaction with a 200 OK.

The following procedure describes how to configure test calls in the Web interface. You
can also configure this using the table ini file parameter, Test_Call or CLI command,
configure system > test-call > test-call-table.
Version 6.8
By default, you can configure up to five test calls. However, this number can be
