Add or Remove SIP Ports for Monitoring

You can add or remove SIP ports for monitoring. In your environment, firewalls may prohibit monitoring on the default SIP ports. Or, the needs of your network may require that you monitor multiple SIP ports for load balancing, for example.

You can change port number in the vcAgentCurrentState.txt file.

Follow these steps:

Open a command-prompt window on the collector server that monitors the SIP ports.
Stop the CA UCM Collector Communication service.
```
net stop “CA UCM Collector”
```
Important: Stop the service before changing the vcAgentCurrentState.txt file. Otherwise, your changes may be overwritten because the collector saves configuration settings to the .txt file when it stops.
After the service stops, navigate to the following location:
```
install directory\voipmonitor\bin
```
Open the vcAgentCurrentState.txt file in a text editor such as Notepad.

In the .txt file, search for text "SIP port=" as shown below. Ports 5060 and 5061 are monitored by default:

Changed directives=0x7f009fbe
Show summary dialog=0
Save interval=1
…
…
SCCP port=2000
MGCP port=2427
Q931 port=2428
H225 port=1720
SIP port=5060;5061
TPKT capture=1

Add or remove port numbers on the SIP port= line. Separate port numbers with a semi-colon, but no space. For example:
- To add port 5066: SIP port=5060;5061;5066
- To remove port 5061: SIP port=5060
Important: The SIP port= line can contain no more than 5 port numbers.
Save and close the text file.
In the command-prompt window, start the Collector service:
```
net start “CA UCM Collector”
```

(Optional) To verify your changes, open the voipagent log in the
[install directory]\voipmonitor\logs directory.

Log entries similar to the following indicate that your changes were successful

13:56:51 Severity 4 - [PacketReader] Setting (UDP & TCP) port filters: 5060 (SIP).
13:56:51 Severity 4 - [PacketReader] Setting (UDP & TCP) port filters: 5061 (SIP-2).
