Security
For information about toll fraud, see the DEFINITY®, Avaya Aura Communication Manager, or
Avaya Aura Communication Manager Branch documents on the Avaya support Web site. The
1600 Series IP Telephones cannot guarantee resistance to all Denial of Service attacks.
However, there are checks and protections to resist such attacks while maintaining appropriate
service to legitimate users.
You also have a variety of optional capabilities to restrict or remove how crucial network
information is displayed or used. These capabilities are covered in more detail in
Chapter 5: Server Administration.
●Support signaling channel encryption while registering, and when registered, with
appropriately administered Avaya Media Servers.
Note:
Note: Signaling and audio are not encrypted when unnamed registration is effective.
●Restricting the response of the 1600 Series IP Telephones to SNMP queries to only IP
addresses on a list you specify.
●Specifying an SNMP community string for all SNMP messages the telephone sends.
●Restricting dialpad access to Local Administration Procedures, such as specifying IP
addresses, with a password.
●Removing dialpad access to most Local Administration Procedures.
●Restricting the end user’s ability to use a telephone Options application to view network
data.
As of Release 1.1, three existing security-related parameters can be administered on the call
server and downloaded with encrypted signaling, in addition to unencrypted HTTP or encrypted
HTTPS. Those parameters are SNMP community string, SNMP Source IP Addresses, and
Craft Access Code (PROCPSWD).

Registration and Authentication

The Avaya Media Server supports using the extension and password to register and
authenticate 1600 Series IP Telephones. For more information, see the current version of your
call server administration manual.
