Polycom SIP 3.0.2 manual Single Registration, SIREN22

Administrator’s Guide Addendum for the SoundStation IP 7000

Single Registration

The SoundStation IP 7000 phone supports a single registration.
When the phone is unable to register with the call control server, the icon
is shown (outline). Once the phone is able to register, the icon	is
shown (solid).

Audio Codecs

The following table summarizes the SoundStation IP 7000 phone’s new audio codec support:

					Effective
Algorithm	MIME Type	Bit Rate	Sample	Frame Size	audio
			Rate		bandwidth
G.722.1C	G7221/	24 Kbps	32 Ksps	20ms - 80ms	14 KHz
	32000	32 Kbps
		48 Kbps
Lin16	L16/16000	25.6 Kbps	16 Ksps	10ms	7 KHz
	L16/32000	51.2 Kbps	32 Ksps		14 KHz
	L16/48000	76.8 Kbps	48 Ksps		22 KHz
Siren14	SIREN14/	24 Kbps	32 Ksps	20ms - 80ms	14 KHz
	16000	32 Kbps
		48 Kbps
Siren22	SIREN22/	32 Kbps	32 Ksps	20ms - 80ms	14 KHz
	48000	48 Kbps
		64 Kbps

	Note		The network bandwidth necessary to send the encoded voice is typically 5-10%
			(confirm number) higher than the encoded bit rate due to packetization overhead.
			For example, a G.722.1C call at 48kbps consumes 5xkbps of network bandwidth.
			Configuration changes can performed centrally at the boot server:
Central		Configuration file:		Specify codec priority, preferred payload sizes, and jitter buffer tuning
(boot server)		sip.cfg		parameters.
