Monitoring Gateway SIP Trunk Status via SSH through Command line

Try this one for Active Discovery.  My applies to is hasCategory("CiscoVoiceDialControl")  It was created for telnet but you should be able to tweak it.  It is multi instance.

// Import the LogicMonitor expect helper class
import com.santaba.agent.groovyapi.expect.Expect

// Get the hostname and credentials from the device property table
def hostname = hostProps.get("system.hostname")
def userid = hostProps.get("ssh.user")
def passwd = hostProps.get("ssh.pass")
def port = 23  // Default Telnet port
def timeout = 5000  // Timeout in milliseconds

// Open a Telnet connection
def telnet_connection = Expect.open(hostname, port, timeout)
telnet_connection.expect("Username:")
telnet_connection.send("${userid}\n")
telnet_connection.expect("Password:")
telnet_connection.send("${passwd}\n")
telnet_connection.expect("#")

// Disable pagination and set terminal width
telnet_connection.send("terminal width 0\n")
telnet_connection.expect("#")
telnet_connection.send("terminal pager 0\n")
telnet_connection.expect("#")

// Send command to display the SIP UA register status
telnet_connection.send("show sip-ua register status\n")
telnet_connection.expect("#")

// Collect the command output
def config = telnet_connection.before()

// Close the Telnet connection
telnet_connection.send("exit\n")
telnet_connection.expectClose()

// Print the raw output for debugging
//println config

// Initialize a list to hold parsed entries
def entries = []

// Use regex to match each line of data
def matcher = config =~ /(\d+)\s+(\d+)\s+(\d+)\s+(\w+)\s+(\w+)\s+(\S+)/

while (matcher.find()) {
    def line = matcher.group(1)
    def peer = matcher.group(2)
    def expires = matcher.group(3).toInteger()
    def reg = matcher.group(4)
    def survival = matcher.group(5)
    def p_associ_uri = matcher.group(6)

    // Map Reg field: 0 for "yes" and 1 for "no"
    def regStatus = (reg == "yes") ? 0 : 1

    // Create an entry map with the mapped Reg value
    def entry = [
        'Line': line,
        'Peer': peer,
        'Expires': expires,
        'Reg': regStatus,  // Mapped value
        'Survival': survival,
        'P-Associ-URI': p_associ_uri
    ]
    
    // Add entry to entries list
    entries << entry
}

// Output the parsed entries for LogicMonitor to pick up as individual datapoints
entries.each { entry ->
    // println "Line: ${entry['Line']}, Peer: ${entry['Peer']}, Expires: ${entry['Expires']}, Reg: ${entry['Reg']}, Survival: ${entry['Survival']}, P-Associ-URI: ${entry['P-Associ-URI']}"
    println "${entry.Line}##${entry.Line}"
}

// Return a success code
return 0

Below is for data collection.

// Import the LogicMonitor expect helper class
import com.santaba.agent.groovyapi.expect.Expect

// Get the hostname and credentials from the device property table
def hostname = hostProps.get("system.hostname")
def userid = hostProps.get("ssh.user")
def passwd = hostProps.get("ssh.pass")
def port = 23  // Default Telnet port
def timeout = 5000  // Timeout in milliseconds

// Open a Telnet connection
def telnet_connection = Expect.open(hostname, port, timeout)
telnet_connection.expect("Username:")
telnet_connection.send("${userid}\n")
telnet_connection.expect("Password:")
telnet_connection.send("${passwd}\n")
telnet_connection.expect("#")

// Disable pagination and set terminal width
telnet_connection.send("terminal width 0\n")
telnet_connection.expect("#")
telnet_connection.send("terminal pager 0\n")
telnet_connection.expect("#")

// Send command to display the SIP UA register status
telnet_connection.send("show sip-ua register status\n")
telnet_connection.expect("#")

// Collect the command output
def config = telnet_connection.before()

// Close the Telnet connection
telnet_connection.send("exit\n")
telnet_connection.expectClose()

// Print the raw output for debugging
//println config

// Initialize a list to hold parsed entries
def entries = []

// Use regex to match each line of data
def matcher = config =~ /(\d+)\s+(\d+)\s+(\d+)\s+(\w+)\s+(\w+)\s+(\S+)/

while (matcher.find()) {
    def line = matcher.group(1)
    def peer = matcher.group(2)
    def expires = matcher.group(3).toInteger()
    def reg = matcher.group(4)
    def survival = matcher.group(5)
    def p_associ_uri = matcher.group(6)

    // Map Reg field: 0 for "yes" and 1 for "no"
    def regStatus = (reg == "yes") ? 0 : 1

    // Create an entry map with the mapped Reg value
    def entry = [
        'Line': line,
        'Peer': peer,
        'Expires': expires,
        'Reg': regStatus,  // Mapped value
        'Survival': survival,
        'P-Associ-URI': p_associ_uri
    ]
    
    // Add entry to entries list
    entries << entry
}

// Output the parsed entries for LogicMonitor to pick up as individual datapoints
entries.each { entry ->
    println "${entry.Line}.Reg:${entry.Reg}"
}

// Return a success code
return 0

I have one datapoint named Status and it looks like this.
