Administration and Provisioning

The SIP Firmware for the IP Phone 1120E and 1140E must be provisioned using TFTP,
HTTP or FTP. The required TFTP, HTTP or FTP server are provided by the customer. The
SIP user must be provisioned on the Nortel Communication Server system. It is essential
that both the SIP username and a corresponding DN alias be configured on the server.

Firmware Content and Update Information

The SIP Firmware for IP Phone 1120E and 1140E supports remote firmware changes and
updates through both a manual and automated process using the TFTP, HTTP or FTP
protocol. Updates, including firmware, language files, and configuration files, may be
obtained when the phone is powered up, at specific times pre-configured by the system
administrator, or at any time upon manual request of the user. Firmware updates are done
via the SIP Firmware update/provisioning mechanism.

Customers will need to make arrangements for the TFTP/FTP/HTTP servers. A trial copy of
Windows or Linux version of TFTP server application can be obtained from several leading
vendors such as
Firmware Release update process involves below steps.

1) Existing SIP Firmware for the IP Phone 1120E/1140E can be updated to SIP Firmware Release 1.1
(06A4C39d29/06A5C39d29 version). The IP Phone 1120E or 1140E may be shipped with SIP version of the
Firmware that may not be the current release. Updating the SIP firmware will require a TFTP server.

2) To upgrade existing UNIStim Firmware for the IP Phone 1120E/1140E, first update the IP Phone1120E/1140E to
minimum required UNIStim Firmware version 0624C1B/0625C1B. The IP Phone 1120E or 1140E may be shipped
with default UNIStim version lower than the minimum required version.

3) Once the IP Phone 1120E/1140E is at 0624C1B/0625C1B version, the IP Phone can be updated to SIP Firmware
Release 06A4C39d29/06A5C39d29 version. UNIStim Firmware supports the TFTP or UFTP protocols. Updating
UNIStim firmware and switching from UNIStim firmware to SIP Firmware will require a TFTP server (UFTP is not
supported).

IMPORTANT NOTE: The SIP Firmware Release for IP Phone 1120E and 1140E is a migration to the SIP
protocol for these IP Phones. Loading the SIP Firmware will overwrite the existing firmware such as
UNIStim (i.e., note that it will not be possible to run both the SIP and UNIStim Firmware concurrently).

Technical Advisements

Minimum Hardware for SIP Firmware Release on the IP Phone 1120E and 1140E

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E is only supported on the
GA hardware release of the respective IP Phone model.

Security -

The SIP Firmware Release for IP Phone 1120E and 1140E supports two methods for
NAT traversal of the signaling path:

SIP PING is a Nortel protocol for NAT traversal for SIP signaling only.

The STUN protocol lets a client discover the presence and type of NATs between the
client and the public Internet. In addition, a client can discover the mapping between the
private IP address and port number and the public IP address and port number.
Typically, an Enterprise or a service provider operates a STUN server in the public
Internet or internet domain. A STUN server can be located using DNS SRV records
using the domain as the lookup. STUN typically uses the well-known port number 3478.
The NAT traversal method can be selected manually through the Device Settings menu
or configured through the device configuration file.

SIP Firmware Release 1.1 for IP Phone 1120E and 1140E also supports NAT traversal
for the Media path. However, STUN protocol cannot coexist with Application Layer
Gateway (ALG), Media Portals or RTP Proxy servers. If STUN is configured on the SIP
Firmware Release, ensure none of these devices are configured in the SIP proxy server.

NAT Traversal & STUN protocol

• SIP_PING

• Simple Traversal of User Datagram Protocol through Network Address

Translators (STUN)

Secure Real-Time Transport Protocol (SRTP) and Transport Layer Security (TLS)

SIP-based Secure RTP and TLS are a planned enhancement for a future SIP
Firmware release.

Nortel Product Bulletin# P-2007-0235-Global – Rev 1 Page 17 of 20

Nortel Product Bulletin# P-2007-0235-Global – Rev 1

802.1X and Extensible Authentication Protocol (EAP)

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E supports 802.1 X/EAP
device authentications. The authentication protocol currently supported is EAP-MD5.
Customers need to procure appropriate RADIUS/authentication servers (both HW/SW).
Certificate based authentication is planned for a future release.

Single User Login

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E only supports a single
user logged in per phone. Other Nortel IP Phones or firmware may allow for more than
one user (or directory number) to be logged in or displayed at a time.

Multiple Appearance Directory Number (MADN)

SIP Firmware Release 1.1 for IP Phone 1120E and 1140E supports Multiple
Appearance Directory Number (MADN) Single Call Appearance (SCA) feature for Nortel
Communication Servers CS2000 and CS2100. MADN allows a Directory Number (DN)
to appear on more than one IP Phone 1120E or 1140E. MADN with Single Call
Arrangement (SCA) allows multiple phones to appear as a single line to a caller. Any
one of the IP Phone 1120E or 1140E configured in a MADN group can initiate or answer
a call, but only one call can be active at any given time. Other users in the group can join
the active call by picking up the phone. It is highly recommended that Call Waiting
Feature is enabled for the MADN users. With call waiting feature active and when the
single line is busy, MADN users on active calls can make/receive new calls. Privacy, call
transfer, three-way call, and call park features are also supported for the MADN users.
MADN SCA group/users and features like call waiting should be configured on the
Communication Server. Please refer to the respective CS2000/CS2100 documentation
for MADN configuration details. For MADN users, call forwarding (local to the IP Phone)
and Do Not Disturb features are not supported. SIP Firmware supports call transfers for
active MADN calls prior to bridging the call. Any MADN user (including primary) can
answer the call, and then perform a blind or consultant transfer.

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E supports starcode(*79)

SIP URI Dialing

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E supports URI dialing.

Some Communication Servers may not support URI dialing and in such cases, attempt
to make calls from the Call softkey menu of SIP Firmware may not complete and users
may get an error message. In addition, as a valid URI is to be entered for monitoring a
user’s presence state the presence state/updates may not be reflected accurately with
Communication Servers that may not support URI.

SIP User Identification

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E supports a maximum
length of 18 characters for the SIP User Id. When assigning the SIP User ID, please
ensure it is limited to a maximum of 18 characters.

Automatic Call Back/Automatic Recall (ACBAR)

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E supports Automatic Call

Back(ACB) and Automatic Recall (AR) with certain Nortel Communication Servers i.e.
CS2000/CS2100. ACB places a call to the last outgoing number dialed by the user.
When a user calls a line that is busy, the ACBAR service notifies the user that the line is
busy and offers the user the option to monitor the destination line. Once the destination
line is free, the call is placed again. Automatic Recall (AR) places a call to the last
incoming caller to a user. Please note ACBAR service needs to be provisioned on the
Communication Server.

DHCP

When a DHCP server has to issue a new IP address to the IP Phone 1120E or 1140E

after a lease expires, the IP Phone may go through a reboot and recover process and
this process may take up to five minutes for the IP Phone to get back to its ready state to
make/receive calls. In addition, if a user is on a call, the call may be dropped and the IP
Phone may go through the reboot and recover process.

If the DHCP lease expires, the

IP Phone must initiate a new negotiation of an IP address from the server's pool of
addresses. DHCP lease may expire so the network does not run out of IP addresses or
due to instability in the network. DHCP lease expiration is not a common event.

User Interface

The SIP Firmware Release 1.1 for IP Phone 1120E and 1140E has several user

interface enhancements as detailed below:

only needs to press the menu item number on the keypad or press the select key.
The user is no longer required to press the OK key for confirmation
