1.5 Problem reports
Before you report problems to your conferencing service provider, please be prepared to
provide basic information about the phone, configuration files and logs, and a full
description of the issue.
•Basic information about the phone:
•Phone serial number
•Version of software currently on the phone
•Configuration files and logs:
•Phone configuration: Provide the relevant configuration files from the provisioning
server for the phone, or export your entire configuration.
•Any relevant log files showing the problem occurring. If you have not enabled logging,
you should enable it for the phone experiencing the issue, reproduce the issue, and
provide those logs.
•Have you been able to reproduce the problem? If so, please detail how.
•Is there anything that you think might be relevant in the log? Did anything unusual
occur? Did the system generate any high-severity log messages? If so, please attach
an extract.
•Description of the issue:
•When did the problem occur? How often does it occur? Is there any pattern or trend to
the occurrence?

pattern or trend to the affected users?
•Any symptoms observed.
•Any error messages displayed on the phone UI or web interface.
•Any obvious triggers. (What was the user doing before the error message displayed?)
•If the issue was reproducible. (Does it happen regularly or after certain tasks are
performed?)
•How widespread the issue appears to be. (Does it affect a single user only or the whole
organization?)
•Any other information you have that might assist in understanding the issue.
•What operating system and version are being used by the client? What browser and
version are being used by the client?

2 Solution architecture
The Dolby Conference Phone supports advanced functionality, including local conferencing,
multiple call appearances, Hypertext Transfer Protocol Secure (HTTPS) secure provisioning,
and deployment in conference service provider and IP PBX environments.
•Dolby Conference Phone software application
•Network configurations
•Operational modes of the Dolby Conference Phone
2.1 Dolby Conference Phone software application
The Dolby Conference Phone software consists of two basic components: the application
that loads the phone software when the phone is first powered on and implements the
phone functions and features, and the configuration files that contain the phone settings.
The phone software application manages the protocol stack, the DSP, the UI, and the
network interaction. This application implements these functions and features:
•Voice over Internet Protocol (VoIP) signaling for a range of voice telephony functions
using Session Initiation Protocol (SIP) signaling for call setup and control
•Industry-standard security techniques for ensuring that all provisioning, signaling, and
media transactions are authenticated and encrypted
•Advanced audio signal processing for communications using a group of audio codecs
•Flexible provisioning methods to support various deployment scenarios
The phone software application also performs these tasks once you power up or reboot the
phone:
•Enables you to set various network and provisioning options
•Formats the file system, and removes any application and configuration files if new
updates are downloaded
•Determines what files on the provisioning server are required by the phone
•Downloads the application and configuration files
•Installs the application, and uploads an event log file from the boot cycle to the
provisioning server
The phone software application is a binary file image and contains a digital signature that
prevents tampering or the loading of rogue phone software images. There is a new image file
in each new release of phone software.
2.2 Network configurations
From an administrator’s perspective, the Dolby Conference Phone is a SIP endpoint in a
network that interoperates with other compatible hardware, such as application servers,
media servers, gateways, switches, voice bridges, and other endpoints.
For the Dolby Conference Phone to successfully operate as a SIP endpoint in the network,
you will require:
2.1 Dolby Conference Phone software application
Dolby Conference Phone 3.1 administrator's guide
12 January 2017 9

•A working IP network
•Network routers and switches configured for VoIP
•VoIP gateways configured for SIP
•Adequate firewall security
•The latest Dolby Conference Phone software image (or a compatible version)
•An active, configured call server to receive and send SIP messages
•Dolby Conferencing Console or provisioning server on the IP network
There are many ways to set up a phone network using the Dolby Conference Phone. This
figure is just one example of a network setup.

2.3 Operational modes of the Dolby Conference
Phone
The operational modes of the Dolby Conference Phone can integrate with the conferencing
service provider as a conference endpoint, register to an IP PBX call control platform as a SIP
endpoint, or do both simultaneously.
The mode the phone operates in determines what features are supported. For example, if
the operational mode is set to Conferencing Only Mode, then the phone cannot be
configured to connect to an IP PBX, and features such as forwarding and transferring will be
unavailable. Similarly, if the operational mode is set to IP PBX Only Mode, then the phone
cannot be configured to connect to a Dolby Voice enabled conferencing service provider.
