Appendix E: The Push Feature

Introduction

Release 2.1 of the 4600 Series IP Telephones provided support for a feature called “Push,” which applies to the 4610SW, 4620, and 4620SW Telephones. Release 2.2 introduced additional IP Telephones, the 4621SW, the 4622SW, and the 4625SW, to which the Push feature also applies. In all cases, the Push feature applies only to telephones supporting H.323, and not to SIP IP telephones.

Push gives the System Administrator the capability to use WML protocol to:

• send content to a telephone without first receiving a user request, and
• potentially override what the user is otherwise experiencing.

You can send pushed content to a single telephone, a group of phones, or the entire enterprise.
