Overview

This chapter provides an overview of the Session Initiation Protocol (SIP)
application and how the phones fit into the network configuration.
SIP is the Internet Engineering Task Force (IETF) standard for multimedia
conferencing over IP. It is an ASCII-based, application-layer control protocol
(defined in RFC 3261) that can be used to establish, maintain, and terminate
calls between two or more endpoints. Like other voice over IP (VoIP)
protocols, SIP is designed to address the functions of signaling and session
management within a packet telephony network. Signaling allows call
information to be carried across network boundaries. Session management
provides the ability to control the attributes of an end-to-end call.
For the SoundPoint IP / SoundStation IP phones to successfully operate as a
SIP endpoint in your network, it must meet the following requirements:
• A working IP network is established.
• Routers are configured for VoIP.
• VoIP gateways are configured for SIP.
• The latest (or compatible) SoundPoint IP / SoundStation IP phone SIP
application image is available.
• A call server is active and configured to receive and send SIP messages.

http://www.polycom.com/techpartners1/ .
This chapter contains information on:
• Where SoundPoint IP / SoundStation IP Phones Fit
• Session Initiation Protocol Application Architecture
• Available Features
• New Features in SIP 3.1
To install your SoundPoint IP / SoundStation IP phones on the network, refer
to Setting up Your System on page 3-1. To configure your SoundPoint IP /
SoundStation IP phones with the desired features, refer to Configuring Your
2 - 1
Administrator’s Guide SoundPoint IP / SoundStation IP
System on page 4-1. To troubleshoot any problems with your SoundPoint IP /
SoundStation IP phones on the network, refer to Troubleshooting Your
SoundPoint IP / SoundStation IP Phones on page 5-1.
Where SoundPoint IP / SoundStation IP Phones Fit
The phones connect physically to a standard office twisted-pair (IEEE 802.3)
10/100 megabytes per second Ethernet LAN and send and receive all data
using the same packet-based technology. Since the phone is a data terminal,
digitized audio being just another type of data from its perspective, the phone
is capable of vastly more than traditional business phones. AsSoundPoint IP /
SoundStation IP phones run the same protocols as your office personal
computer, many innovative applications can be developed without resorting
to specialized technology.

Session Initiation Protocol Application Architecture
Configuration
Resource
Files
bootROM
Application
The software architecture of SIP application is made of 4 basic components:
• BootROM—loads first when the phone is powered on
• Application—software that makes the device a phone
• Configuration—configuration parameters stored in separate files
• Resource Files—optional, needed by some of the advanced features
Overview
BootROM
The bootROM is a small application that resides in the flash memory on the
phone. All phones come from the factory with a bootROM pre-loaded.
The bootROM performs the following tasks in order:
1. Performs a power on self test (POST).
2. (Optional) Allows you to enter the setup menu where various network on
provisioning options can be set.
The bootROM software controls the user interface when the setup menu is
accessed.
3. Requests IP settings and accesses the boot server to look for any updates
to the bootROM application.
If updates are found, they are downloaded and saves to flash memory,
eventually overwriting itself after verifying the integrity of the download.
4. If a new bootROM is downloaded, format the file system clearing out any
application software or configuration files that may have been present.
2 - 3
Administrator’s Guide SoundPoint IP / SoundStation IP
5. Download the master configuration file.
This file is either called <MAC-address>.cfg or 000000000000.cfg . This file
is used by the both the bootROM and the application for a list of other files
that are needed for the operation of the phone.
6. Examine the master configuration file for the name of the application file,
and then look for this file on the boot server.
If the copy on the boot server is different than the one stored in flash
memory or, if there is no file stored in flash memory, the application file is
downloaded.
Application
Note
Warning
If the Application is any SIP version prior to 1.5, the bootROM will also download all
the configuration files that are listed in the master configuration file.
7. Extract the application from flash memory.
8. Install the application into RAM, then upload a log file with events from
the boot cycle.
The bootROM will then terminate, and the application takes over.
The application manages the VoIP stack, the digital signal processor (DSP), the
user interface, and the network interaction. The application managed
everything to do with the phone’s operation.
The application is a single file binary image and, as of SIP 1.5, contains a digital
signature to prevent tampering or loading or rogue software images.
If your phones are using bootROM 3.0 or later, the application must be signed.
All SIP 1.5 applications and later are signed, but later patched versions of 1.3 and
1.4 support this feature. Refer to the latest Release Notes to verify if the image is
signed.
2 - 4
Note
There is a new image file in each release of software.
The application performs the following tasks in order:
1. Downloads system and per-phone configuration files and resource files.
These files are called sip.cfg and phone1.cfg by default. You can
customized the filenames.
If the Application is any SIP version prior to 1.5, the bootROM would have
downloaded all the configuration files that are listed in the master configuration file.
Configuration
Overview
2. Controls all aspects of the phone after it has restarted.
3. Uploads log files.
BootROM and Application Wrapper
Both the bootROM and the application run on multiple platforms (meaning all
previously released versions of hardware that are still supported).
The file stored on the boot server is a wrapper, with multiple hardware specific
images contained within. When a new bootROM or application is being saved,
the file is read until a header matching the hardware model and revision are
found, and then only this image is saved to flash memory.
The SoundPoint IP / SoundStation IP phones can be configured automatically
through files stored on a central boot server, manually through the phone’s
local UI or web interface, or a combination of the automatic and manual
methods.
The recommended method for configuring phones is automatically through a
central boot server, but if one is not available, the manual method will allow
changes to most of the key settings.
Warning
The phone configuration files consist of:
• Master Configuration Files
• Application Configuration Files
Configuration files should only be modified by a knowledgeable system
administrator. Applying incorrect parameters may render the phone unusable. The
configuration files which accompany a specific release of the SIP software must be
used together with that software. Failure to do this may render the phone unusable.
Master Configuration Files
The master configuration files can be one of:
• Specified master configuration file
• Per-phone master configuration file
• Default master configuration file
For more information, refer to Master Configuration Files on page A-2.
2 - 5
Administrator’s Guide SoundPoint IP / SoundStation IP
Application Configuration Files
Typically, the files are arranged in the following manner although parameters
may be moved around within the files and the filenames themselves can be
changed as needed. These files dictate the behavior of the phone once it is
running the executable specified in the master configuration file.
The application files are:
• Application—It contains parameters that affect the basic operation of the
phone such as voice codecs, gains, and tones and the IP address of an
application server. All phones in an installation usually share this category
of files. Polycom recommends that you create another file with your
organization’s modifications. If you must change any Polycom templates,
back them up first. By default, sip.cfg is included.
• Per-phone—It contains parameters unique to a particular phone user.
Typical parameters include:
— display name
— unique addresses
Each phone in an installation usually has its own customized version of
user files derived from Polycom templates. By default, phone1.cfg is
included.
Note
Central Provisioning
The phones can be centrally provisioned from a boot server through a system
of global and per-phone configuration files. The boot server also facilitates
automated application upgrades, logging, and a measure of fault tolerance.
Multiple redundant boot servers can be configured to improve reliability.
In the central provisioning method, there are two major classifications of
configuration files:
• System configuration files
• Per-phone configuration files
Parameters can be stored in the files in any order and can be placed in any
number of files. The default is to have 2 files, one for per-phone setting and one
for system settings. The per-phone file is typically loaded first, and could
contain system level parameters, letting you override that parameter for a
given user. For example, it might be desirable to set the default CODEC for a
remote user differently than for all the users who reside in the head office. By
adding the CODEC settings to a particular user’s per-phone file, the values in
the system file are ignored.
Verify the order of the configuration files. Parameters in the configuration file loaded
first will overwrite those in later configuration files.
2 - 6
Overview
The following figure shows one possible layout of the central provisioning
method.
Resource Files
Manual Configuration
When the manual configuration method is employed, any changes made are
stored in a configuration override file. This file is stored on the phone, but a
copy will also be uploaded to the central boot server if one is being used. When
the phone boots, this file is loaded by the application after any centrally
provisioned files have been read, and its settings will override those in the
centrally provisioned files.
This can create a lot of confusion about where parameters are being set, and so
it is best to avoid using the manual method unless you have good reason to do
so.
In addition to the application and the configuration files, the phones may
require resource files that are used by some of the advanced features. These
files are optional, but if the particular feature is being employed, these files are
required.
Some examples of resource files include:
• Language dictionaries
• Custom fonts

Overview
— Multiple Call Appearances—The phone supports multiple concurrent
calls. The hold feature can be used to pause activity on one call and
switch to another call.
— Multiple Line Keys per Registration—More than one line key can be
allocated to a single.
— Multiple Registrations—SoundPoint IP desktop phones support
multiple registrations per phone. However, SoundStation IP
conference phones support a single registration.
— Network Address Translation—The phones can work with certain
types of network address translation (NAT).
— Presence—Allows the phone to monitor the status of other
users/devices and allows other users to monitor it. Requires call
server support.
— Real-Time Transport Protocol Ports—The phone treats all real- time
transport protocol (RTP) streams as bi-directional from a control
perspective and expects that both RTP end points will negotiate the
respective destination IP addresses and ports.
— Recording and Playback of Audio Calls — Recording and playback
allows the user to record any active conversation using the phone on
a USB device. The files are date and time stamped for easy archiving
and can be played back on the phone or on any computer with a media
playback program what supports the .wav format. This feature is part
of the Productivity Suite.
— Server Redundancy—Server redundancy is often required in VoIP
deployments to ensure continuity of phone service for events where
the call server needs to be taken offline for maintenance, the server
fails, or the connection from the phone to the server fails.
— Shared Call Appearances—Calls and lines on multiple phones can be
logically related to each other. Requires call server support.
— Static DNS Cache—Set up a static DNS cache and provide for negative
caching.
— Synthesized Call Progress Tones—In order to emulate the familiar
and efficient audible call progress feedback generated by the PSTN
and traditional PBX equipment, call progress tones are synthesized
during the life cycle of a call. Customizable for certain regions, for
example, Europe has different tones from North America.
— Voice Mail Integration—Compatible with voice mail servers.
• Audio Features
— Acoustic Echo Cancellation—Employs advanced acoustic echo
cancellation for hands-free operation.
— Audio Codecs—Supports the standard audio codecs.

Administrator’s Guide SoundPoint IP / SoundStation IP
— Automatic Gain Control—Designed for hands-free operation, boosts
the transmit gain of the local user in certain circumstances.
— Background Noise Suppression—Designed primarily for hands-free
operation, reduces background noise to enhance communication in
noisy environments.
— Comfort Noise Fill—Designed to help provide a consistent noise level
to the remote user of a hands-free call.
— DTMF Event RTP Payload—Conforms to RFC 2833, which describes
a standard RTP-compatible technique for conveying DTMF dialing
and other telephony events over an RTP media stream.
— DTMF Tone Generation—Generates dual tone multi-frequency
(DTMF) tones in response to user dialing on the dial pad.
— IEEE 802.1p/Q—The phone will tag all Ethernet packets it transmits
with an 802.1Q VLAN header.
— IP Type-of-Service—Allows for the setting of TOS settings.
— Jitter Buffer and Packet Error Concealment—Employs a
high-performance jitter buffer and packet error concealment system
designed to mitigate packet inter-arrival jitter and out-of-order or lost
(lost or excessively delayed by the network) packets.
— Low-Delay Audio Packet Transmission—Designed to minimize
latency for audio packet transmission.
— Voice Activity Detection—Conserves network bandwidth by
detecting periods of relative “silence” in the transmit data path and
replacing that silence efficiently with special packets that indicate
silence is occurring.
— Voice Quality Monitoring—Generates various quality metrics
including MOS and R-factor for listening and conversational quality.
This feature is part of the Productivity Suite.
• Security Features
— Local User and Administrator Privilege Levels—Several local settings
menus are protected with two privilege levels, user and
administrator, each with its own password.
— Configuration File Encryption—Confidential information stored in
configuration files must be protected (encrypted). The phone can
recognize encrypted files, which it downloads from the boot server
and it can encrypt files before uploading them to the boot server.
— Custom Certificates—When trying to establish a connection to a boot
server for application provisioning, the phone trusts certificates
issued by widely recognized certificate authorities (CAs).
— Incoming Signaling Validation—Levels of security are provided for
validating incoming network signaling.
