IP Phone Release Notes 2.1

Usability Features

Ability to Disable Call Waiting

Currently on the IP phones, the call waiting feature notifies the user currently on the phone, of a new incoming call. Release 2.1 allows a User or Administrator the ability to disable the call waiting feature, so that the new incoming call is automatically rejected by the phone with a busy message.

If you disable call waiting on the phone, and the user is on a call, any further incoming calls will receive busy unless “Call Forward Busy” or “Call Forward No Answer and Busy” is configured on the phone. It will then forward the call according to the rule configured. The phone can only:

•transfer the currently active call or

•accept transferred calls if there is no active calls.

If call waiting is disabled:

•on the 57i CT bases, and the handset is currently on a call, all additional incoming calls are rejected on the handset.

•intercom calls are treated as regular incoming calls and are rejected.

•pre-dialing with live dial pad disabled still accepts incoming calls.

•the “Incoming Call Cancels Dialing” parameter is ignored because the incoming call is automatically rejected.

•the Missed Calls List does not get updated with details of calls.

•the Blind Transfer feature on the phone may not work if two calls are made to the phone at one time.

You can disable call waiting using the configuration files or the Aastra Web UI.

Usability Features

Mexico Tone Set Added to the IP Phones

You can configure ring tone sets on a global-basis on the IP phones. Ring tone sets consist of tones customized for a specific country. A new ring tone set for Mexico has been added in Release 2.1.

When you configure the country's tone set, the country-specific tone is heard on the phone for the following:

-dial tone

-secondary dial tone

-ring tone

-busy tone

-congestion tones

-call waiting tone

-ring cadence pattern

A User and Administrator can configure ring tone sets using the Aastra Web UI and the IP Phone UI. Additionally, an Administrator can configure ring tone sets using the configuration files.

See your IP Phone-specific User Guide or the IP Phone Administrator’s Guide for information about configuring ring tone sets.

IP Phone Release Notes 2.1

Usability Features

Customizable Callers List and Services Keys

The IP phones currently have a Callers List key (all 5i Series phones) and a Services key (55i, 57i, and 57i CT). In Release 2.1, two new parameters have been added that allow you to specify URI overrides for these keys. These parameters are:

•services script

•callers list script

Specifying URIs for these parameters cause the creation of an XML custom application instead of the standard function of the Callers List and Services keys.

An Administrator can configure these parameters using the configuration files only.

Creating Customizable Callers List and Services Keys

You use the following parameters to customize the Callers List and Services function.

Parameter –	Configuration Files	aastra.cfg, <mac>.cfg
services script

Description	Allows you to specify a specific URI for accessing services after
	pressing the Services key. When this parameter is set, it overrides the
	standard function of the Services key.

Format	Alphanumeric characters

Default Value	N/A

Range	N/A

Example	services script: http://10.50.100.234/test.xml


Parameter –	Configuration Files	aastra.cfg, <mac>.cfg
callers list script

Description	Allows you to specify a specific URI for accessing the Callers List after
	pressing the Callers List key. When this parameter is set, it overrides
	the standard function of the Callers List key.

Format	Alphanumeric characters

Default Value	N/A

Range	N/A

Configuration Parameters No Longer Case Sensitive

Previously, the configuration parameters an Administrator entered in the configuration files were case sensitive and had to be entered exactly the way they appeared in the IP Phone Administrator’s Guide (all lowercase).

In Release 2.1, the parameters are no longer case sensitive and can be entered in either upper or lower case as desired.

Deployability Features

Server and Protocol Identification via DHCP Feature

The IP Phones now support additional download protocols according to RFC2131 and RFC1541 to support DHCP option 66.

Option 66 is part of the DHCP Offer message that the DHCP server generates to tell the phone which configuration server it should use to download new firmware and configuration files. In addition to supporting the IP address of a TFTP server in this field, the phone now supports a URI format for specifying the other configuration server types.

Your DHCP server configuration file, such as the dhcpd.conf file, may include one of these lines to configure the configuration server protocol and the server details.

Protocol	Format	Examples

HTTP	http://<server>/<path>	option tftp-server-name “http://192.168.1.45”;
		option tftp-server-name “http://192.168.1.45/path”;
		option tftp-server-name “http://httpsvr.example.com/path”;

HTTPS	https://<server>/<path>	option tftp-server-name “https://192.168.1.45”;
		option tftp-server-name “https://192.168.1.45/path”;
		option tftp-server-name “https://httpssvr.example.com/
		path”;

Security Features

Transport Layer Security (TLS) Support

The phones now support a new transport protocol called Transport Layer Security (TLS) and Persistent TLS. TLS is a protocol that ensures communication privacy between the SIP phones and the Internet. TLS ensures that no third party may eavesdrop or tamper with any message.

TLS is composed of two layers: the TLS Record Protocol and the TLS handshake protocol. The TLS Record Protocol provides connection security with some encryption method such as the Data Encryption Standard (DES). The TLS Handshake Protocol allows the server and client to authenticate each other and to negotiate an encryption algorithm and cryptographic keys before data is exchanged. TLS requires the use of specific security certificate files to perform TLS handshake:

•Root and Intermediate Certificates

•Local Certificate

•Private Key

•Trusted Certificate

When the phones use TLS to authenticate with the server, each individual call must setup a new TLS connection. This can take more time when placing each call. Thus, the IP phones also have a feature that allows you to setup the connection to the server once and re-use that one connection for all calls from the phone. It is called Persistent TLS. The setup connection for Persistent TLS is established during the registration of the phone. If the phones are set to use Persistent TLS, and a call is made from the phone, this call and all subsequent calls use the same authenticated connection. This significantly reduces the delay time when placing a call.
