My system is Windows Server 2016 running Version 20.0 Update 4 (Build 487 Release) using Flowroute for my SIP provider.

Can someone tell me how to find the setting to disable the " Put Public IP in SIP VIA Header" option as mentioned in the linked post. I am not able to find this setting in my Trunk settings.
thanks

Try this solution I gave just a short while ago, to test and see the audio packets

Use the 3CX connection monitoring tool, to see which side of the connection is at fault

Enable the connection monitoring on a user (top right menu of a user, or from the Team tab



This can monitor a connection for a period of 1, 3, 5 or 7 days

See the report of each call.

This is done through the reports, or through the event log



Click on the log entry to expand the report



here you will be able to see any packet loss and see the quality of the call and which of the 2 sides is at fault.

This is a configuration option that is available when you configure a generic SIP trunk.

With a supported provider everythig is preconfigured to the requirements of the provider.

This shouldn't affect the one user however.

Issue seems to have been in a Chrome permission setting that the user excepted and it is now working. She enabled this before we were able to monitor a call.
thanks for the help
