SIP Firmware Release 2.0 for IP Phone 1120E Administration

NN43112-300 03.03 Standard

15 September 2008

New in this release

The following changes are introduced for SIP Firmware Release 2.0 for IP Phone 1120E Administration (NN43112-300).

Server Supplied User Credentials

This release adds support for downloading a users login credentials from a central repository. The login credentials are associated with the MAC address of the set. This feature simpliﬁes installation of the IP Phone by allowing it to automatically log into the SIP proxy server without end user intervention.

To provision this feature see "Set conﬁguration commands" (page 60).

Expansion module for the IP Phone 1100 Series when connected to IP Phone 1100 series SIP Client

An expansion module providing 18 additional feature keys, can be attached to a Nortel IP Phone 1120E with SIP ﬁrmware. Up to three expansion modules can be added to the phone. The feature keys in the expansion module provide the same functionality as the feature keys on the IP Phone.

Additionally, this feature adds the ability to automatically populate the extra feature keys, using the friends list or the address book as sources.

For more information on the Expansion module refer to, SIP Firmware for IP Phone 1100 Series Expansion Module User Guide (NN43110-301).

To provision this feature see "Feature conﬁguration commands" (page 42).

IEEE 802.1ab Link Layer Discovery support

Discovery protocols provide a mechanism to identify devices attached to a network. Popular network-management systems use automated discovery to obtain the topology of a network. These applications detect adds and removals, provide Layer 3 information, and group the attached devices into IP subnets.

SIP Firmware Release 2.0 for IP Phone 1120E Administration

NN43112-300 03.03 Standard

15 September 2008

8 New in this release

IEEE has developed 802.1ab Link Layer Discovery Protocol (LLDP), a standard for discovering the physical topology between neighboring devices.

802.1ab LLDP deﬁnes a standard method for Ethernet network devices

such as switches, routers and IP Phones to advertise information about themselves to other nodes on the network and store the information they discover in a MIB.

This feature implements 802.1ab and its IEEE 802.1/802.3 and TIA-MED organizationally speciﬁc extensions.

To provision this feature see "802.1ab Link Layer Discovery Protocol"

(page 99) and Procedure 13 "Provisioning the Device Settings parameters" (page 111). The parameters in Table 18 "TLV formats" (page 100) can be

conﬁgured on the IP Phone.

IP Phone 1120E with SIP ﬁrmware PRACK and UPDATE support feature

The combined support of PRACK and UPDATE allows the IP Phone 1120E with SIP ﬁrmware to provide reliability to provisional responses, and the ability to update session parameters during call setup as well as after the initial invite has received a ﬁnal response. The combination of reliable provisional responses (PRACK) and the ability to change session parameters before call establishment (using UPDATE) will improve the IP Phone 1120E interactions with some PSTN networks where the parameters of a session may need updating before the call is established.

PRACK is used for adding reliability to provisional responses (such as 180 Ringing) in SIP messaging. The PRACK request plays the same role as ACK, but for provisional responses. [RFC 3262]

UPDATE allows a client to update parameters of a session (such as the set of media streams and their codecs) but has no impact on the state of a dialog. In that sense, it is like a re-INVITE, but unlike re-INVITE, it can be sent before the initial INVITE has been completed. This makes it very useful for updating session parameters within early dialogs. [RFC 3311]

To provision this feature see "Feature conﬁguration commands" (page 42).

RFC 3581

This feature implements an extension to SIP for Symmetric Response Routing for the IP Phone 1120E with SIP ﬁrmware. This extension permits the conduction of SIP dialogs through a Symmetric Network Address Translator (NAT) using UDP.

SIP Firmware Release 2.0 for IP Phone 1120E Administration

NN43112-300 03.03 Standard

15 September 2008

This allows the phone to work from behind and/or in front of a symmetrical NAT with servers and/or clients that support RFC 3581. In particular, it enhances the capability of the IP Phone 1120E with SIP ﬁrmware to interoperate with other proxies and to work in any network conﬁguration. For this feature to work properly, the receiving end device must support RFC 3581.

To provision this feature see "Feature conﬁguration commands" (page 42).

RTP port conﬁguration

This RTP port conﬁguration feature provides options to set or change RTP ports in the Nortel IP Phone 1120E with SIP ﬁrmware. RTP port conﬁguration is available only through the provisioning server.

To provision this feature see "Feature conﬁguration commands" (page 42).

Voice Quality Monitoring

When Voice Quality Monitoring (VQMon) is enabled, the IP Phone 1120E with SIP ﬁrmware gathers statistics regarding the quality metrics of the current call and sends reports to the server at regular intervals. The call-related statistics contain condensed information about the SIP Session Description Protocol (SDP), the Call ID, the local and remote address, voice quality-related statistics, Zulu times for start-time and the time the report was sent. The voice quality-related statistics include jitter, packet loss, delay, burst gap loss, listening R-factor, R-LQ, R-CQ, MOS-LQ and MOS-CQ. The reports can be used for QoS monitoring. A third party server is required to collect and organize the data.

Distinctive ringing and Call waiting 9

End of call reports are sent with the Zulu time indicating start of session and end of session; session interval reports are sent with interval deﬁned in the conﬁguration using time stamps, and alert reports are sent with current time stamps with a limited frequency of 1 report per 5 seconds if any alert violation persists.

Release 2.0 supports interworking with SQLMediator 1.1. To provision this feature see "VQMon conﬁguration commands" (page 57).

Distinctive ringing and Call waiting

The Distinctive ringing feature permits users to distinguish between different types of call actions by playing a different ringing pattern. The request for a speciﬁc ringing pattern comes from the server at the time the call is being established. The Nortel IP Phone 1120E with SIP ﬁrmware does not request the playing of distinctive ringing from other parties. The ringing patterns to be used follow the North American standards which also include call waiting

tones for the times when the receiving end is already engaged in a call session. The predeﬁned ringing pattern identiﬁers available on the phone accommodate usage by the BroadWorks servers.

To provision this feature see "Feature conﬁguration commands" (page 42).

Shared Call Appearance

The Shared Call Appearance feature allows a given line to be conﬁgured with multiple locations, essentially allowing multiple endpoints to login to the system while using the same external number. Any one of these locations can be used to originate or receive calls. Any call appears to the other party to be originating from or terminating to the same number, regardless of the location initiating or receiving the call.

The Shared Call Appearance feature allows a user to pick up a call that was put on hold by another user of the same group and it allows a user to join an active call of another user in the group.

The Shared Call Appearance feature is supported on BroadWorks servers. To provision this feature see "Feature conﬁguration commands" (page 42).

Transfer to Voice Mail

The transfer to Voice Mail feature enables a soft key to transfer an incoming call, or a call waiting, to a voice mail box on the IP Phone 1120E with SIP ﬁrmware.

The transfer to Voice Mail feature is supported on MCS 5100 servers only. To provision this feature see "Feature conﬁguration commands" (page 42).

Overview

Introduction

This chapter describes the hardware and ﬁrmware features of the Nortel IP Phone 1120E and provides a brief overview of Session Initiation Protocol (SIP).

SIP overview

Session Initiation Protocol (SIP) is a signaling protocol used for establishing multimedia sessions in an Internet Protocol (IP) network.

SIP is a text-based protocol similar to HTTP and SMTP. With the introduction of SIP to IP Phones, telephony integrates easily with other Internet services. SIP allows the convergence of voice and multimedia.

IP Phone 1120E with SIP Firmware

The IP Phone 1120E connects to an IP network using an Ethernet connection. All voice and signaling information is converted into IP packets and sent across the network.

The IP Phone 1120E can be ordered with UNIStim Firmware installed or with SIP Firmware installed. UNIStim Firmware and SIP Firmware use the same hardware, but the model number of an IP Phone 1120E with UNIStim Firmware is different from the model number of an IP Phone 1120E with SIP Firmware.

If you have an IP Phone 1120E with UNIStim Firmware, you can convert the ﬁrmware to SIP Firmware. To download the most recent version of SIP Firmware, see "Download the SIP Firmware to the provisioning server"

(page 30).

This guide explains how to:

•

conﬁgure the provisioning server and the DHCP server. Note: The provisioning server is where the ﬁrmware and the conﬁguration ﬁles for the IP Phone 1120E reside. This is not the IP Client Manager (IPCM) of the call server.

•

convert an IP Phone 1120E with UNIStim Firmware to an IP Phone 1120E with SIP Firmware

Note: Converting the ﬁrmware on an IP Phone 1120E from UNIStim Firmware to SIP Firmware overwrites the UNIStim Firmware. The IP Phone 1120E cannot operate in both modes simultaneously. A switch from UNIStim to SIP Firmware or SIP to UNIStim Firmware requires a ﬁrmware reload.

The following ﬁgure shows the main components of the IP Phone 1120E with SIP Firmware.

Conﬁgure the provisioning server and, optionally, the DHCP server. The function of the provisioning server is to provide conﬁguration options to every IP Phone 1120E throughout the network. TheDHCP server can be conﬁgured to provide basic network-conﬁguration data or a more comprehensive set of network-conﬁguration data for the IP Phone 1120E with SIP Firmware.

Load SIP Firmware on the IP Phone 1120E. Conﬁgure the initial network-conﬁguration parameters on the IP

Phone 1120E with SIP Firmware.

If you have UNIStim Firmware on your IP Phone 1120E, the ﬁrmware must be converted from UNIStim to SIP before you proceed with the following instructions. See the chapter "Upgrade and convert the IP Phone 1120E ﬁrmware" (page

79) for instructions on how to convert the ﬁrmware on an IP Phone 1120E from

UNIStim to SIP.

If the IP Phone 1120E is installed with SIP Firmware, further SIP Firmware upgrades can be done with a TFTP, an FTP, or an HTTP server.

How provisioning works

Provisioning is performed without interaction with the call server. The IP Phone 1120E with SIP Firmware connects directly with the provisioning server in order to retrieve ﬁrmware ﬁles and conﬁguration ﬁles. In this case, the provisioning server is not to be confused with the IP Client manager on the call server. The methods of provisioning are:

•

Automatic provisioning at power-up: After the IP Phone 1120E powers up or is reset, it checks the provisioning server for the latest ﬁles.

•

Provisioning through user interaction: The end user can manually check for updates by pressing the Services Context-sensitive soft key and selecting System. In the System menu select Check for Updates.

•

Automatic provisioning at a preconﬁgured time: The IP Phone 1120E with SIP Firmware checks for updates every 24 hours, at a time speciﬁed by a parameter in the device conﬁguration ﬁle.

The following steps are taken when provisioning updates occur. The IP Phone 1120E with SIP Firmware:

1. connects to the provisioning server

2. retrievesthe provisioning ﬁle (1120eSIP.cfg) from the provisioning server

3. reads and acts upon the content of the provisioning ﬁle and decides whether any other ﬁle is needed, based on a set of rules. If ﬁles need to be downloaded to the IP Phone 1120E, a new ﬁle transfer session starts
