Phase 0 testing: Run tests on phones as configured on one PBX: Asterisk. This is to validate basic "phone is not broken" behavior.
Phase 1 testing: Move phones to the PBXs as assigned. Make calls, hang up, and verify two-way voice. Replicate testing from 2004 SIP iLabs to verify basic connectivity. Connect to NuFone.
Phase 2 testing: For each phone on each SIP Proxy, run the following tests with every other phone on that same proxy. For the sake of labels, the first phone you're testing we'll call the A phone, and the second phone will be called the B phone. Some of these tests require a third phone, which is not being tested, called the C phone.
