Push Administration

62 4600 Series IP Telephones Application Programmer Interface (API) Guide

Recommendations:

If the domain from Table 5: URI Examples is “associate.hacker.com” and the TPS string is

“company.com”, then the domain “hackercompany.com” will also match the TPS string and

pass the security validation. For example, if the TPS string is “company.com” & the URLs are:

http://www.company.com - this URL is acceptable.

http://associate.company.com - this URL is acceptable.

http://www.hackercompany.com - this URL is acceptable.

In this case “hackercompany” also passes the security validation.

To avoid such security issues, the administrator must set the TPS string to “.company.com”

(where there is a “dot” before “company”).

For example, if the TPS string is “.company.com” and the URLs are:

http://www.company.com - this URL is acceptable.

http://associate.company.com - this URL is acceptable.

http://www.hackercompany.com - this URL is not acceptable.

In this case “hackercompany” fails the security validation.

Subscription Service

The phone provides a set of values such as the IP Address and user telephone number to

subscription servers when the telephones register with the media server. An explicit

subscription message can also be sent to the phone using <Push type=”subscribe”… /> to

re-subscribe the phones.

Note:

Note: See Chapter 3: Creating Push Messages for more details on sending a

re-subscribe Push Request to the telephone.

Applications must maintain their own database of information for each phone. Databases can

be built with respect to a group of telephones or an individual phone.

A typical example in a corporate work environment is to have distribution lists according to

specific teams. An application can only target pushes to that team such as “team meeting

reminders” with conference bridge numbers, etc.

Once an application builds a database that has the required information of all of the telephones

in the network, it can target Push Content or an audio stream to a specific phone or a group of

phones. Additionally, Push Initiator Servers can poll the phone to update its database.

Note:

Note: A phone in a logoff state does not unsubscribe from the Subscription server.
