Title: Troubleshooting Chirp Registration Issues and Checking Port Connectivity

Introduction:
If you encounter issues with registering your Chirp softphone or experiencing registration failures shortly after logging in, this guide provides troubleshooting steps to identify and resolve potential causes. Two methods are presented: checking for firewall issues on your home network and using the telnet command to test port connectivity.

Method 1: Checking for Firewall Issues on Your Home Network:
If other agents on different networks can successfully register their Chirp softphones and you are using your home Wi-Fi, a firewall issue might be causing the problem. Follow these steps to troubleshoot:

1. Connect your laptop or desktop, where Chirp is installed, to a different network (e.g., use your mobile hotspot or USB tethering with mobile data).
2. Attempt to register your softphone on the new network.
3. If you are able to successfully register on the new network, it indicates that the issue lies with your home Wi-Fi network.
4. Contact your Wi-Fi/internet service provider and request assistance in opening the necessary ports.

Method 2: Using Telnet Command to Check Port Connectivity:
The telnet command can be used to test connectivity to the server from your Windows 10 system. Follow these steps:

1. Enable the Telnet feature on your Windows system by following the instructions in this article: How to Enable Telnet in Windows.
2. Open the Command Prompt on your Windows 10 system.
3. Type the following command and press Enter:

   shell
   telnet <server_ip_address> 5060
   

   Replace <server_ip_address> with the IP address of the Linux server or the subdomain used for Chirp login (e.g., 172.16.0.38 or portal02.txcontact.com).
   
4. Check port 5060 for connectivity. (If you are using Secure SIP i.e. TLS enabled on the server then 5061)
5. If the port is accessible and there are no network restrictions, you will see a blank screen or a message indicating a successful connection.

Example (Successful Connection):

Trying <linux_server_ip_address>...
Connected to <linux_server_ip_address>.
Escape character is '^]'.


Example (Connection Failed):

Trying <linux_server_ip_address>...
telnet: Unable to connect to remote host: Connection refused


If you receive a "Connection refused" message or any other error, it suggests that the port is not accessible or network restrictions are preventing the connection.

Following these troubleshooting methods should help you identify and resolve issues with Chirp registration failures or softphone restarts. If the problem persists, consider reaching out to support@telenetix.in for further assistance.
