About Us - Case Studies

We had a sit down, meeting the prospect to review the issues, resulting in a lengthy discussions with their IT department and others. In the conversation, it was discovered that they do not have call quality issues in terms of poor audio. The issue was directly related to call completion. At times when placing or receiving calls, there were busy signals or dead air. After this meeting, we took a careful view of their network topology, reviewed the configuration and monitored the voice traffic. The prospect's SIP provider was delivering voice services via the internet. While this is common practice, it does create a large attack surface regarding voice network security. In review of logs, debugs and captures, it was determined that the prospect's (now customer) were using a firewall as the edge device to interface the SIP trunk provider as well as internet services. In short, this was the root cause of the voice issues and needed to be addressed. Too many bad actors attempting to exploit the voice services on the internet.
