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.

If you enable call waiting (default), the user has the option of accepting a
second call while currently on the first call. If you disable call waiting, and
a user is currently on a call, a second 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:

the phone for the following:
- dial tone
- secondary dial tone

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 –
services script
Description Allows you to specify a specific URI for accessing services after
Format Alphanumeric characters
Default Value N/A
Range N/A
Example services script: http://10.50.100.234/test.xml
Parameter –

Description Allows you to specify a specific URI for accessing the Callers List after
Format Alphanumeric characters
Default Value N/A
Range N/A
Example callers list script: http://10.50.100.234/test.xml

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.

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/

Security Features
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.
