In this solution, the customer would typically utilize the following:
- one or more dedicated voice circuits
- ViBE technology
- a dedicated voice switch (POE or not), that will only be used for phones
Key to this solution is that the phones cannot have additional devices plugged into them in 'bridge' mode (i.e. switch into phone, phone into PC) - there is no internet access from this network, only voice access.
The design is outlined below, with the Visio template attached (2010).
