Once you have installed the NetBorder Call Analyzer and started the service, you should place an outbound call to verify that a call is successfully put through, and that call progress analysis is functioning and returning the expected results.
This chapter assumes that the NetBorder Call Analyzer software has been successfully installed on your system. For installation procedures, please proceed to the Installation section

Prerequisites to making a test SIP call
To make a test SIP call, you will need the following:
...
You will also need to configure the softphone to use NetBorder Call Analyzer as an outbound proxy. Refer to the Configuration Section
Configuring as an Outbound Proxy
By default, the NetBorder Call Analyzer is configured to serve as an outbound proxy. Before making your test call, you will need to configure your softphone to route calls through NetBorder.
...
By configuring the softphone to use an outbound proxy, the softphone will initiate all its SIP communication through the outbound proxy; that is, the callee’s SIP URI will be processed by NetBorder. In other words, all SIP requests and responses will be sent through NetBorder.
Making a Call Without NCA
To further verify the NetBorder Call Analyzer installation, you should place an outbound call to ensure that it is put through and you receive valid results.
...
start your soft phone application
Place a call using the soft phone. Enter the phone number in the “CallTo” field using dotted notation, as follows:
sip:[phone number or extension]@[IP address]:[port]
For example: sip:1024@192.168.11.103:5061.
In the example above, X-Lite is being used to call the telephone extension “1024”, reachable via the PSTN gateway at 192.168.11.103:5061.
Place the call. If you are using X-Lite, press Enter or click the green telephone icon in the left side of the application
Verify that you hear a ringing tone and ultimately, once the call is connected, audio on the other end
Interact with the application to verify that audio is coming through on both ends of the call
Note: If you fail to hear audio, your firewall may be preventing calls from being put through. Also, if the call is established successfully and no audio is heard, the firewall may be blocking the media (RTP) packets. Try disabling your firewall.
When finished, hang up. If you are using X-Lite, click the red telephone icon on the right side of the application
...
If you wish, you can view SIP messages related to the call to verify that you have received the expected results. The call-log files are located in the following directory:
...
[NETBORDER_INSTALLDIR]\logs\call-logs where [NETBORDER_INSTALLDIR] is the root folder of the installation (for example, C:\Program Files\Sangoma NetBorder Platform 2.0\logs\call-logs). By default, call-log files are saved in subdirectories based on date and time.
Making a Call With NCA
Now place an outbound call with CPA on to verify that call progress analysis is functioning properly and returning useful results. The CPA scenario is triggered by placing “ ;cpd=on ” in the SIP Invite. Therefore, this process is very similar to the previous procedure, except that you add “ ;cpd=on ” to the phone number you are dialing.
...
Start your soft phone application.
Place a call using the soft phone. Enter the phone number in the “Call To” field using dotted notation, as follows:
Code Block sip:[phone number or extension]@[IP address]:[port]
For example: sip:1024@192.168.11.103:5061.
Append the following to the phone number you entered: “;cpd=on”.
For example: sip:1024@192.168.11.103:5061; cpd=on.
Place the call.
...
Verify that you hear a ringing tone and ultimately, once the call is connected, audio on the other end.
Interact with the application to verify that audio is coming through on both ends of the call.
When finished,hangup.
If you are using X-Lite, click the red telephone icon on the right side of the application.
If you receive an error message, such as a “Decline” message from the softphone application, see What to do if a call is not connected on page 43.
Now take a look at the call-log files to verify the results of the call and particularly of the call progress analysis.
Do the following:
a) Open the call-log files located in the following directory:
