PABX Troubleshooting: Alcatel Lucent System

Job ID: 38101046

Budget: ₹1,500 – ₹12,500 INR

I'm having issues with my Alcatel Lucent PABX system. Recently, I've been getting an error reading "One or more IP of the defined DHCP are already used by devices", which is affecting outgoing calls outside the organization.

For a little background, here are some of the recent changes in our network configuration:

- New ISP

Ideally, you'd have:
- Extensive experience with Alcatel Lucent PABX systems
- Strong understanding of network configuration, specifically dealing with DHCP related issues
- Familiarity with network troubleshooting and potential issues following an ISP change

Please be prepared to dive into the issue at hand, and provide effective solutions quickly. Thank you.
