Procedure

The purpose of this article is to provide a sample configuration. At the time of article creation, this device was in a known working state on the firmware used.  Keep in mind different firmware versions will interact with hosted VoIP services in different ways. While this device may be fully functional on the tested and/or current firmware version, it is possible newer revisions will cause disruptions in service or make a device fully compliant with the required settings for hosted VoIP services where it was previously not.

Note: Traffic Shaper / Bandwidth Management does not appear to actually set reserved traffic as specified.
