Introduction

The replaces header is used in SIP call control applications. The Replaces header is used to logically replace an existing SIP dialog with a new SIP dialog. This can be used to enable a variety of features, for example: "Attended Transfer" and "Call Pickup". 

For some platforms, the behavior needs to be changed. We have seen the following issues where the setting needed to be changed.

  • Unattended transfer, the call is signaled as 2e incoming call.
  • Group call pick-up
Auto-provisioning

This feature can be disabled/enabled only via auto-provisioning. Software 2.23 or higher is needed.
