Healthcare
This is a real-life Use Case of a Mutare Customer and provides a high-level summary of the scenario and business problems resolved with the Mutare Voice Traffic Filter solution.
The Client
Academic healthcare, education and research system including more than 100 affiliated hospitals, clinics, and health care facilities with 5,000+ health professionals serving a broad range of medical needs for their patients and educational needs for their students.
Problem Definition
IT administrators were aware that they had a significant problem with spam calls intruding on their voice network and affecting both staff and patient lines. They also recognized that a large portion of these unwanted calls (as much as 45% according to industry studies) were likely scams with malicious intent and constituted a significant risk both to possible data/regulatory breach as well as to patient safety. As a customer of Mutare’s solution for voicemail retrieval, transcription and notification, this organization again turned to Mutare to see what the company could do about their growing problem with voice spam intrusions.

The Story
Mutare’s analysis of the organization’s incoming voice traffic revealed that more than 12% of their incoming voice traffic could be positively identified as unwanted voice spam. Not only did that represent a significant security risk, but it was also clearly undermining staff workflow and network performance. While looking to block those calls, administrators were concerned about any system that might be too aggressive in flagging a suspicious number as spam and inadvertently block what was actually a legitimate patient or physician call. Those concerns were alleviated by the Mutare Voice Traffic Filter’s voice CAPTCHA, a unique feature that adds a second layer of vetting for callers suspected as spam but not conclusively identified as such. Mutare’s solution is also platform-agnostic and so unaffected by the complexity of the organization’s mixed-platform environment.
