- SIP Connectivity: Test the connections to SIP endpoints and SIP-aware firewalls in the network path.

- DNS Resolution: Test the server's ability to resolve DNS hostnames, which is required by SIP devices and trunks.

- Packet Trace: Capture a log of traffic passing over the network.

- Teleworker Network Analyzer: Test voice quality and remote IP device connectivity to the MBG server.
