UCC Networks, a Cisco Professional Services partner specializing in Unified Communications solutions, has announced that Cisco Call Manager (Unified Communications Manager) version 12.5 will officially reach End of Support (EoS) on August 31, 2025. Businesses that continue to operate on this version after the deadline risk security vulnerabilities, operational downtime, and vendor support.
Once support ends for CUCM 12.5, organizations can expect:
- No security updates – increasing exposure to cyber threats.
- No bug fixes or feature enhancements – leaving known issues unresolved.
- No Technical Assistance Center (TAC) support – making outages more difficult and costly to resolve.
- Potential compatibility issues – affecting new devices, apps, and integrations.

- Enhanced security and compliance with modern standards.
