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.

•Where SoundPoint IP / SoundStation IP Phones Fit
•Session Initiation Protocol Application Architecture
•Available Features
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

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
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
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.

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.
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.
Application
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.
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.
Note 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.
Warning 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.
Note 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.
