There are multiple types of end-user endpoint devices such as PC software, IP phones, VoIP adaptors and gateways. Endpoints are responsible for originating, handling and ending conversations. Heterogeneous VoIP networks may have multiple types of endpoints with varying degrees of compatibility with the VoIP server and between each other. This is especially true for SIP-based VoIP networks.
A network analyzer identifies and displays the model names of endpoint devices, allowing tracking down connectivity problems and often fixing them with a simple software or firmware update without hunting around the network.
