CUCM SIP Normalization and Transparency Scripting Example

Posted on October 29, 2019 by

Purpose: The purpose of this document is to describe handling, pass through and manipulation of SIP Alert-Info header information from 3rd party alerting systems or SIP enabled nurse calling systems such as Rauland Responder 5.  The Alert-Info header can be leveraged to play an alternative ringtone on the end device signaling a call that has a higher importance than typical calls.  A differentiated ringtone can indicate call urgency without the end user having to unclip a wireless phone from his/her belt to answer or otherwise address the call while occupied with another critical task.

Cisco Configuration “Expect” Backup Script

Posted on June 14, 2012 by
