Troubleshooting

    Temporarily Register Devices to a Different Core

    The VoIP Help Page Team·2 min read·Last updated: March 14, 2026

    ### Scope

    There are times when a route to a specific core is resulting in poor call quality or other issues due to an intermediary hop. As a last resort, you can use the this article to temporarily register devices to a different core other than the client's parent core. These steps will not guarantee a resolution of the issue and should only be done after having already performed the troubleshooting steps to eliminate other possible resolutions. As a reminder, these steps are meant to be temporary until resolution is found since pointing devices to a different core can lead to cross core calls.

    Requirements

    • Access to the Manager Portal

    • Evidence of Loss and Latency on the route between the Client's network and the datacenter they are registered to (A traceroute using Ping Plotter)
