The SoundStructure VoIP Interface
12 - 29
Using a Central Provisioning Server
You can centrally provision SoundStructure VoIP Interfaces from a provision-
ing server through a system of global configuration files and SoundStructure
VoIP Interface-specific configuration files system. The central provisioning
method uses the MAC address of the SoundStructure VoIP Interface to specify
the set of configuration files to use from the provisioning server.
The provisioning server facilitates automated application upgrades, logging,
and fault tolerance. To improve reliability, you can configure multiple redun-
dant provisioning servers. Parameters can be stored in the files in any order
and can be placed in any number of files. For example, it might be desirable to
set the default audio codec for a remote user differently than for office users.
By adding the audio codec settings to a particular user’s per-phone file, the
values in the broader system file are ignored.
Using Manual Provisioning
You can manually configure the SoundStructure VoIP Interface by using the
Web Configuration Utility. Any changes you make are stored in a configura-
tion override file that will override any configuration settings that may been
performed with a provisioning server. The override file is stored on the Sound-
Structure VoIP Interface, but a copy is also uploaded to the central
provisioning server (if one is being used). When the SoundStructure VoIP
Interface boots, the SoundStructure VoIP Interface software loads the override
file. The settings in this file override the settings in the centrally provisioned
files.
Understanding the Hierarchy of SoundStructure VoIP Interface Settings
The VoIP parameters can be configured by files on a provisioning server, from
the Web Configuration Utility, or from SoundStructure Studio. Because there
are multiple ways to set these parameters there is a hierarchy to which settings
are used: the SIP settings from the central provisioning server are used unless
overridden by a higher priority setting from the Web Configuration Utility
settings.
SoundStructure Studio provides an interface for a small subset of the overall
SoundStructure VoIP Interface settings including network settings and
room-based settings such as auto answer enable, ringtone selection, entry and
exit tones, and the tone volume. All other settings are configured via the Web
Configuration Utility or via configuration files on a central provisioning
server. When SoundStructure VoIP Interface parameters are set within Sound-
Structure Studio those parameters are synchronized with the web interface
settings and stored in the SoundStructure VoIP Interface. SoundStructure-spe-
cific telephony parameters such as auto answer, entry and exit tones, and tone
volumes are stored within the SoundStructure device configuration file.
If you are not using a provisioning server, Polycom recommends using the
Web Configuration Utility for setting the VoIP parameters.
