Overview

You noticed that calls to a particular MS Teams number made from Zoom phone do not complete. Calling from mobile works normally.

Solution

To start with troubleshooting, we will need fresh call samples. Reproduce the issue and open a ticket with Support, making sure to describe the issue and any symptoms you observe, and add at least two call samples in the following format:

• Calling From Number:
• Calling To Number:
• Date of call: dd/mm/yy
• Time of call: xx:xx am/pm (time zone)
• Trouble observed: Inbound or Outbound
• Description of the failing scenario

Verification

Once the root cause is fixed, try to replicate the issue to confirm that it is no longer there.
