We had several isolated reports of incoming calls immediately dropping to a fast busy or dead air today after rolling out some network changes to prepare for the device firmware upgrade which was pushed out.

This was not widespread and primarily affected users with specific NAT setups and ISPs. Based on reports that we received from users, it was less than 1%, but still a decent number.

We've been working on this issue throughout the night and have isolated it and corrected the NAT handling for those users.

It should be fully corrected now. If you continue to see this issue, please update your ticket for assistance.
