Cisco this week advised customers using its 7800 and 8800 series IP phones they should patch a variety of high-priority vulnerabilities that could lead to denial of service and other security problems.
The company issued five security advisories, four for the 8800 and one for both the 8800 and 7800 series of IP phones. The 8800 is a high-end business desktop device that features high-definition video and mobile device integration. The 7800 is more of a general business IP phone.
