About VoIP Testing and Test Resources
This Note describes a few simple tests that you should carry out once you have installed your VoIP phone and the dmClub resources that can help you with the testing.
You should carry out these tests in order: they start with the lowest possible requirements and work up to testing the full system.
You can carry out these tests whenever you like, if you want to ensure that your VoIP phone is still working properly. They will not change your phone's configuration.
Duration
These tests should take you around five minutes to complete.
