    A customer of ours with a mix of Grandstream GXP2140/1630 phones are currently nonstop ringing. This only occurred after our system automatically updated to V15.5 SP3.

    Has anyone else experienced this issue?

    Hello @jzollo

    Please update your phones to the supported firmware for these phones and make sure you are using the default templates. You can find the supported firmware here
