Cisco CallManager (CCM) is the software-based call-processing component of the Cisco IP telephony solution which extends enterprise telephony features and functions to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. All Cisco CallManager versions are vulnerable to these Denial of Service (DoS) attacks, which may result in services being interrupted or servers rebooting.
