Monitoring Gateway SIP Trunk Status via SSH through Command line

Question

Hi,I am trying to monitor the status of the Gateway SIP trunk using the command "show sip-ua register status" via SSH. However, I am encountering issues while running a custom script provide by the support team. Initially, when I ran the script a few times, I received an error: "Unable to establish the SSH Connection". After some time, the error changed to "No Signature Method."I have verified the SSH connection from the collector server to the end device, and it works fine when I manually establish the SSH session. I also tested my own script , but it returned a similar error:&nbsp;"Error: Unable to establish SSH session/channel."I have attached the error snapshot and the script I am using for reference. Please guide me on how to monitor the SIP status via the command line using SSH.When running the command "show sip-ua register status", the output is either&nbsp;Yes (registered) or No (unregistered) from the device end. In LogicMonitor, the expected output should be:Yes = 0No = 1I tried to attach the Script but it will not support Txt Format, Sorry for the inconvenienceBelow is the script Provided by the support teamimport com.santaba.agent.groovyapi.expect.Expect;// Get the hostname and credentials from the device property tablehostname = hostProps.get("system.hostname");userid = hostProps.get("ssh.user");passwd = hostProps.get("ssh.pass");// Ensure required properties are not nullif (!hostname || !userid || !passwd) {&nbsp; &nbsp; throw new Exception("Missing required device properties: hostname, ssh.user, or ssh.pass.");}// Initiate an SSH connection to the host using the provided credentialsdef ssh_connection = Expect.open(hostname, userid, passwd);// Wait for the CLI prompt to confirm connectionssh_connection.expect("# "); // Adjust prompt based on your device// Send the `show sip-ua register status` commandssh_connection.send("show sip-ua register status

What kinda device are you attempting to SSH into?
There was an older forum post at https://community.logicmonitor.com/discussions/product-discussions/lm-expect-packages-and-ed25519/14285 that mentions issues with Expect and Fortigate. That LM's Expect might not support some of the newer SSH encryption systems.

Try this one for Active Discovery.&nbsp; My applies to is hasCategory("CiscoVoiceDialControl")&nbsp; It was created for telnet but you should be able to tweak it.&nbsp; It is multi instance.// Import the LogicMonitor expect helper class
