A Local Survivable Processor (LSP) plays a vital role in enterprise communication systems by ensuring telephony services remain active at branch offices during central server outages. It functions as a backup server, handling essential tasks like call routing, voicemail, and emergency calling to maintain business continuity. In the middle of a network failure, the Local Survivable Processor takes over, allowing uninterrupted communication without relying on the main system. It supports automatic failover and recovery, making it ideal for distributed enterprises needing high availability.
For professionals preparing for certifications in VoIP or unified communications, understanding LSP functionality is key. Platforms like CertsHero offer updated study materials and practice exams to help you master such topics and succeed in your certification goals.
