Understand Polycom UC Software Architecture
This section discusses the components of the UC software.
What Is the Polycom UC Software?
The Polycom Unified Communications Software, or Polycom UC Software, manages the protocol stack,
the digital signal processor (DSP), the user interface, and the network interaction. The UC Software
implements the following functions and features on the phones:
● VoIP signaling for a wide range of voice and video telephony functions using SIP signaling for call
setup and control
● SIP signaling
● Industry standard security techniques for ensuring that all provisioning, signaling, and media
transactions are robustly authenticated and encrypted
● Advanced audio signal processing for speakerphone communications using a wide range of audio
codecs
● Flexible provisioning methods to support single phone, small business, and large multi-site
enterprise deployments
The software is a binary file image and contains a digital signature that prevents tampering or the loading
of rogue software images.
There is a new image file in each release of software.
What Are the Configuration Files?
The Polycom UC Software that you download contains template configuration files, valid XML files that
you can change using an XML editor. These template files contain a number of parameters that provision
the phones with features and settings. The template configuration files are very flexible: you can
rearrange the parameters within the template, move parameters to new files, or create your own
configuration files from only those parameters you want. This flexibility is useful when you want to apply
the same features and settings to a large number of phones. Use of the configuration files to provision the
phones with features and settings is called the centralized provision method—the configuration files
enable you to store a single set of configuration files on a central provisioning server and configure all of
your phones to read the same set of files.
Polycom recommends that you configure phones using the centralized provisioning method. However,
there are several methods you can use to configure the phones and you can use one or multiple methods
in combination. Alternatively, you can configure individual phones using the phone’s menu system,
accessible through the local user interface, or using Web Configuration Utility.
