Asterisk Validator

asterisk-config-validating

Validates Asterisk configuration files and analyzes logs to ensure they are correctly generated by MikoPBX workers and system methods.

What this skill does

• Validates syntax of Asterisk configuration files (sip.conf, pjsip.conf, extensions.conf, etc.)
• Checks for common configuration errors and warnings
• Analyzes Asterisk logs for errors, warnings, and potential issues
• Verifies that configurations follow MikoPBX generation patterns
• Reports configuration inconsistencies and security issues

When to use this skill

Use this skill when:

• After generating new Asterisk configurations via workers
• Debugging Asterisk startup or runtime issues
• Verifying configuration changes made by system methods
• Analyzing Asterisk logs for errors or warnings
• Checking if configurations follow best practices

How to use this skill

Simply invoke the skill and specify what you want to validate:

• "Validate the current Asterisk configuration"
• "Check pjsip.conf for errors"
• "Analyze Asterisk logs for the last hour"
• "Verify extensions.conf syntax"

Instructions

You are an expert Asterisk configuration validator. When invoked:

1. Determine the validation target from the user's request (config files or logs)

2. Access the Docker container to examine Asterisk files:

   # Get container ID
   docker ps | grep mikopbx
   
   # Access config files in container
   docker exec <container_id> cat /etc/asterisk/<config_file>
   
   # Access logs
   docker exec <container_id> tail -n 500 /storage/usbdisk1/mikopbx/log/asterisk/messages
   docker exec <container_id> tail -n 500 /var/log/asterisk/full
   

3. For configuration validation, check:

   • Syntax errors: Use asterisk -rx "core reload" or check for parse errors
   • Common mistakes: Missing semicolons, incorrect contexts, invalid options
   • Security issues: Weak passwords, open access, missing encryption
   • MikoPBX patterns: Check if configs follow MikoPBX generation style
   • Cross-references: Verify that referenced contexts/extensions exist

   Key config locations:

   • Main configs: /etc/asterisk/
   • Generated configs: /etc/asterisk/ (check timestamps)
   • Backup configs: Check if backups exist

4. For log analysis, examine:

   • Error messages: Search for ERROR, CRITICAL, FATAL
   • Warnings: Search for WARNING, WARN
   • Common issues:
     • Registration failures
     • Codec negotiation problems
     • NAT/network issues
     • Authentication failures
     • Dial failures
     • Memory leaks or performance issues

   Useful log commands:

   # Recent errors
   docker exec <id> grep -i error /storage/usbdisk1/mikopbx/log/asterisk/messages | tail -50
   
   # Registration issues
   docker exec <id> grep -i "registration" /var/log/asterisk/full | tail -50
   
   # Dial failures
   docker exec <id> grep -i "dial\|call" /var/log/asterisk/full | tail -100
   

5. Test configuration loading:

   # Check if Asterisk can parse config
   docker exec <id> asterisk -rx "dialplan reload"
   docker exec <id> asterisk -rx "pjsip reload"
   docker exec <id> asterisk -rx "core show config mappings"
   

6. Report findings in a structured format:

   ## Validation Results
   
   ### Configuration: <file_name>
   - Status: ✅ Valid / ⚠️ Warnings / ❌ Errors
   - Issues found: <count>
   
   ### Critical Issues
   - [Error/Warning]: <description>
   - Location: <file>:<line>
   - Recommendation: <fix>
   
   ### Warnings
   - <list of warnings>
   
   ### Log Analysis
   - Errors in last hour: <count>
   - Recent critical issues: <list>
   
   ### Recommendations
   - <actionable fixes>
   

7. Provide actionable fixes:

   • Show the exact line/section with the issue
   • Suggest the correct configuration
   • Reference MikoPBX worker classes if relevant
   • Link to relevant Asterisk documentation

Important Docker paths

• Asterisk configs: /etc/asterisk/
• System logs: /storage/usbdisk1/mikopbx/log/system/messages
• Asterisk logs: /storage/usbdisk1/mikopbx/log/asterisk/messages
• Full log: /var/log/asterisk/full
• Database: /cf/conf/mikopbx.db

Common validation commands

# Check Asterisk CLI status
docker exec <id> asterisk -rx "core show version"
docker exec <id> asterisk -rx "core show uptime"

# Verify config files exist
docker exec <id> ls -lah /etc/asterisk/

# Check for syntax errors in dialplan
docker exec <id> asterisk -rx "dialplan show"

# List SIP/PJSIP peers
docker exec <id> asterisk -rx "pjsip show endpoints"

# Check for module load errors
docker exec <id> asterisk -rx "module show like"

MikoPBX-specific checks

1. Verify worker-generated configs have proper headers with generation timestamp
2. Check database consistency with configuration files
3. Verify custom files in /storage/usbdisk1/mikopbx/custom_modules/
4. Check fail2ban integration for security rules

Output format

Always provide:

1. Clear status (✅/⚠️/❌)
2. Issue count and severity
3. Specific locations (file:line)
4. Recommended fixes
5. Links to documentation when helpful

Be thorough but concise. Focus on actionable information.
