Do the voice-over-IP products you're evaluating use these industry-standard protocols or proprietary methods for handling calls?
* Media Gateway Control (MEGACO) — sets how a network gateway converts
the information carried on telephone circuits into data packets carried
over the Internet or other IP networks.
* Session Initiation Protocol — a signaling protocol used to establish,
maintain and terminate multimedia sessions, including voice-over-IP calls.
* H.323 — a widely adopted standard that defines how audiovisual conferencing
data is transmitted across networks.
* G.729 — a protocol that reduces the size of voice packets traveling
across an IP network.
