Call Drop Issue

This morning, I tried to use the conference call service for a church meeting. One of my participants used the one number phone number. They texted the number “Call Me”. It would call and it would work. Then, after 2 minutes, the call would drop. This kept happening until the temporary backup number was used. This is a new issue. Why would this be happening?

Hello,

Sounds like the issue of the caller staying connected to the line is due to their phone provider. The caller that is being dropped from the line will need to contact their phone provider to further troubleshoot this issue.

If the issue is still happening then, the caller will need to continue to use the backup number. Thank you.

But would that make sense if the One Number is not working properly, but the backup number is working? At the same time of the call, the one number has issues staying called-in. The issue was very consistent.
