The language behind the routes
HD Voice, explained.
The HD Voice Exchange begins with a simple belief: when voice is part of the product, quality should be part of the route decision.
- HD Voice
- HD Voice describes voice that carries more of the human voice spectrum than traditional narrowband telephony. The result can be clearer, more natural conversations when the network, endpoints, and codecs support it end to end.
- Wideband AMR
- Wideband AMR is the default HD Voice codec conversation for the Exchange. It is designed to carry a broader voice range and is widely associated with modern mobile voice quality.
- G.722.2
- G.722.2 is a standards name used for Wideband AMR / AMR-WB. It may appear in technical specifications, interconnection discussions, and codec negotiations.
- G.711
- G.711 is a widely used traditional telephony codec. It remains important for interoperability, even when a route is not carrying the wider audio range associated with HD Voice.
- Purple Routing
- Purple Routing is Jeff Pulver’s vision for treating route selection as a quality decision before it is a cost decision.
- Lowest latency practical for the conversation.
- Highest available quality signal across the route.
- Most secure appropriate route for the deployment.
- Cost considered after latency, quality, and security.
The Exchange does not operate routes or guarantee a particular codec, quality level, latency, security posture, price, or service outcome. It helps the right people begin the right conversation.
