	register server. After this time period expires, the SIP register server

	time period has expired.

	Server. The default is 0, which disables this feature.

	ASCII Extended set characters.

	you use RESTART (in the navigation panel).

13.3 Voice Coding

A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital signals back into voice signals. The Prestige supports the following codecs.

13.3.1 G.711

G.711 is a Pulse Code Modulation (PCM) waveform codec. G.711 provides very good sound quality but requires 64kbps of bandwidth.

Pulse Code Modulation (PCM) measures analog signal amplitudes at regular time intervals and converts them into bits.
