Administrator’s Guide - SoundPoint® IP / SoundStation® IP Addendum

1Addendum

This addendum addresses changes to the SoundPoint IP / SoundStation IP SIP 2.0 Administrator’s Guide made by the release of the SoundPoint IP 650 phone.

The SoundPoint IP 650 phone behaves in a similar manner to the SoundPoint IP 601 (supports the SoundPoint IP Expansion Module) unless otherwise specified.

For more information, refer to the Release Notes for the SIP Application, Version

2.0.3 B.

Note

The various .hd. parameters in sip.cfg (such as voice.aec.hd.enable, voice.ns.hd.enable, and voice.agc.hd.enable) are headset parameters. There are not connected to high definition or HD voice.

1.1 Added or Changed Features

1.1.1 Configurable Feature Keys

The SoundPoint IP 650 phone’s default SIP key layouts is the same as the SoundPoint IP 600 and 601. Refer to 3.1.7 Configurable Feature keys on page 29.

1.1.2 Handset, Headset, and Speakerphone

The SoundPoint IP 650 phones are full-duplex speakerphones. Changes can be found in the following parameters in the sip.cfg configuration file:

• Gains <gain/>

Attribute Default

voice.handset.rxag.adjust.IP_650 1 voice.handset.txag.adjust.IP_650 9 voice.handset.sidetone.adjust.IP_650 -3

Attribute Default

voice.headset.sidetone.a

just.IP_650 -3

Important

Polycom recommends that you do not change these values.

1.1.3 LCD Backlight

Backlight intensity on the SoundPoint IP 650 phone has three modes:

• Backlight On

• Backlight Idle

• Dim

You can modify the Backlight On intensity and the Backlight Idle intensity separately. You can select high, medium, low, and off levels for both. Dim mode intensity is determined by the Backlight On intensity and the Backlight Idle intensity together.

Backlight settings can be found in the User Preferences <up/> parameter in the sip.cfg configuration file.

Permitted

Attribute

up.backlight.onIntensity 0 (off),

up.backlight.idleIntensity 0 (off),

Values

1 (low), 2 (medium), 3 (high)

Default Interpretation

3 This parameter controls the intensity

of the LCD backlight when it turns on during normal use of the phone.

1 This parameter controls the intensity

of the LCD backlight when the phone is idle.

Note: If idleIntensity is set higher than onIntensity, it will be replaced with the onIntensity value.

1.1.5 MicroBrowser

The SoundPoint IP 650 phones support an XHTML microbrowser. This can be launched by pressing the Services key.

MicroBrowser parameter changes in the sip.cfg configuration file are as follows:

Attribute Permitted Values Default Interpretation

mb.limits.nodes positive integer 256 Limits the number of tags which the

XML parser will handle. This limits the amount of memory used by complicated pages. A maximum total of 500 (256 each) is recommended. This value is used as referent values for 16MB of SDRAM.

Note: Increasing this value may have a detrimental effect on performance of the phone.

mb.limits.cache positive integer 200 Limits the total size of objects down-

loaded for each page (both XHTML and images). Once this limit is reached, no more images are downloaded until the next page is requested. Units = kBytes. This value is used as referent values for 16MB of SDRAM.

Note: Increasing this value may have a detrimental effect on performance of the phone.

milliseconds) that must be achieved before play out begins for the first time. Once this depth has been achieved initially, the depth may fall below this point and play out will still continue. This parameter should be set to the smallest possible value which is at least two packet payloads, and larger than the expected short term average jitter.
