Call Admission Control (CAC) is the method or process of regulating traffic in voice communications, specifically in wireless mobile networks and in Voice over Internet Protocol (VoIP). Call admission control can also be used to ensure, or maintain, a certain level of audio quality in voice communications networks, or a certain level of performance in Internet nodes and servers where VoIP traffic exists.
Most CAC algorithms work by controlling the total utilized bandwidth, the total number of calls, or the total number of packets or data bits passing a specific point per unit time. If a defined limit is reached or exceeded, a new call may be restricted from entering the network until at least one current call terminates. Another method involves the regulation of calls according to defined characteristics such as priority descriptors. This method prevents new calls from entering the network only if the resources of the central processing unit (CPU) of a particular computer or server would be overburdened by such calls.

CyberHoot’s Minimum Essential Cybersecurity Recommendations
The following recommendations will help you and your business stay secure with the various threats you may face on a day-to-day basis. All of the suggestions listed below can be gained by hiring CyberHoot’s vCISO Program development services.
- Govern employees with policies and procedures. You need a password policy, an acceptable use policy, an information handling policy, and a written information security program (WISP) at a minimum.
- Train employees on how to spot and avoid phishing attacks. Adopt a Learning Management system like CyberHoot to teach employees the skills they need to be more confident, productive, and secure.
- Test employees with Phishing attacks to practice. CyberHoot’s Phish testing allows businesses to test employees with believable phishing attacks and put those that fail into remedial phish training.
- Deploy critical cybersecurity technology including two-factor authentication on all critical accounts. Enable email SPAM filtering, validate backups, and deploy DNS protection, antivirus, and anti-malware on all your endpoints.
- In the modern Work-from-Home era, make sure you’re managing personal devices connecting to your network by validating their security (patching, antivirus, DNS protections) or prohibiting their use entirely.
- If you haven’t had a risk assessment by a 3rd party in the last 2 years, you should have one now. Establishing a risk management framework in your organization is critical to addressing your most egregious risks with your finite time and money.
- Buy Cyber-Insurance to protect you in a catastrophic failure situation. Cyber-Insurance is no different than Car, Fire, Flood, or Life insurance. It’s there when you need it most.
