    Thirdlane VoIP: Great for MSPs, but Demands an Investment in Time

    Date: Apr 23 2025

    Summary: Thirdlane offers a robust system with a level of customization that's invaluable for managing multiple clients. However, it's not a plug-and-play solution. For MSPs willing to invest the time to configure it, it provides long-term stability. If you're after a hands-off, simple deployment, you might need to look elsewhere—but if you're ready to put in the work, it's a great choice.

    Positive: Thirdlane Multi-Tenant VoIP stands out because of how much control it gives us over the system, whether it's configuring multiple clients or handling internal communications. The platform’s ability to manage separate environments under one umbrella is critical for an MSP like ours.

    Negative: The setup process took more time than expected, especially when trying to optimize it for various client needs. There's no real "out-of-the-box" ease for someone new to VoIP systems.
