IP Telephony (IPT) introduces the need for a complete and deliberate approach to applying critical firmware and software updates for all system elements, including endpoints, servers, and the underlying network infrastructure.
This research note explores:
- The maintenance impact of the shift to software-based voice services.
- The scope of software updates required within an IPT deployment.
- Recommended steps for identifying, planning, and applying updates.
Enterprises should build a comprehensive software maintenance plan to protect against security threats to the voice services infrastructure.
