Q
Is any Quality of Service (QoS) implemented on the Motorola voice terminal?
A
Although voice service over the Internet is typically best-effort, the Motorola voice terminal provides upstream voice prioritization to ensure
that upstream voice data has priority over other Web data. This ensures good voice quality even during heavy upstream data transfers such
as e-mail synchronization or file sharing.
Q
What codecs and voice protocols does the Motorola voice terminal support?
A
The Motorola voice terminal supports:
•
Many popular coder/decoders (codecs) including G.711 (a-law and µ-law), G.726(16, 24, 32, and 40 kbps), G.729A/B, G.729E, G.728,
G.723, and others. The configuration of supported codecs depends on your VoIP provider's system.
•
Session Initiation Protocol (SIP) per RFC 3261, Real Time Protocol (RTP) per RFC 1889, and Out of Band Dual Tone Multi Frequency
(OOB DTMF) per RFC 2833.
