Description

Alarm Status

None

Possible Cause

Corrective Action

A network or firewall configuration issue. Persistent cases are usually due to a misconfigured firewall.

Check your network path between the remote set and the receiving equipment. Check the tug.log to determine which set was experiencing the one-way audio. If the tug.log determines the issue is on the WAN network side, contact your IP service provider to determine changes that may have been made to your IP service. Check that the firewall configuration meets the MBG Engineering Guidelines requirements. If the alarm is not resolved, collect required logs and contact Mitel product support.
