Push Administration

60 4600 Series IP Telephones Application Programmer Interface (API) Guide

Trusted Push Server List (TPSLIST)

Depending upon the TPSLIST setting in the script file, the Push Message is either accepted for

additional processing or denied.

An administrator can set the security level using the following domain-based security values for

the TPSLIST parameter in the 46xxsettings.txt script file.

Specifically, the List of Trusted Push Servers contains one or more domains and paths in a DNS

format or an IP Address in dotted-decimal format, separated by commas.

1. The administrator sets the TPSLIST values in the 46xxsettings.txt script file on the TFTP

server. See the 4600 Series IP Telephone LAN Administrator’s Guide on the

http://www.avaya.com/support

Web site for more details.

2. If the value of TPSLIST is null, Push Messages cannot be received and the Push interface

is disabled.

3. If the value of TPSLIST contains only a forward slash character (/), then all Push Messages

are accepted, meaning any Push server is considered a Trusted Push Server.

4. Wild cards such as asterisks are not allowed for URL strings in the TPSLIST.

If the pushed URI string (the value of the Push Request’s href attribute in the <go> tag does

not begin with the proper HTTP schema, http://, the URI string is rejected and the response

back to the Push Initiator contains the following parameters:

To validate a particular pushed URI string, a string-based comparison is done against the values

of the TPSLIST administered in the 46xxsettings.txt script file.
