TestSipUdpApp

SIP Test Application Configuration

The SIP Test Application is a utility application which listens for and sends out UDP or TCP payloads on behalf of other applications.

It exists as a separate application for two reasons:

1. To allow test agents to send/receive UDP and TCP without needing to manage sockets directly,
2. For scalability, to allow multiple processes to serve inbound requests from a single UDP or TCP port.

Here is a configuration example, connecting to a remote host via UDP:

<?xml version="1.0" encoding="utf-8"?>
<n2svcd>
  ...
  <applications>
    ...
    <application name="UDP-SIPTestApp" module="TestSipUdpApp">
      <include>
        <lib>../apps/sip_test/lib</lib>
      </include>
      <parameters>
        <parameter name="local_host"      value="${N2SVCD_TEST_IP}"/>
        <parameter name="local_port"      value="5063"/>
      </parameters>
    </application>
    ...
  </application>
  ...
</n2svcd>

Note the use of ${N2SVCD_TEST_IP}. All parameter value attributes support the use of environment variables to allow a single n2svcd.xml to operate on different platforms without needing to be modified for each platform.
