VoIP security is crucial to protect your wallet, reputation, and keep your communication safe from malicious actors. Here are 12 best practices to keep your VoIP secure:

1. Secure User Credentials with a Strong Password and Two-Factor Authentication — The default passwords provided by the manufacturer are easily found and usually not strong, which makes it important to implement a strong credential management policy. Two-factor authentication should be mandatory for all users.
2. Perform Regular Call Log Reviews — Regular reviews of VoIP traffic in call logs help detect unusual activity such as abnormal call durations, destinations, and the time outgoing calls are being initiated.
3. Disable International Calling or Enable Geo-Fencing — Geo-fencing is used to prevent connections from countries where high numbers of potential hacks originate. IP blacklists can also be used to block connections to known malicious IP addresses.
4. Utilize SaaS for VoIP Calls — Outsourcing PBX and VoIP services to a SaaS provider like Telzio can provide a robust feature set, user-friendly UI, and full support.
5. Stay Up to Date on Security Patches — It’s important to regularly update the firmware on your VoIP phones.
6. Use a Router with a Firewall — Connecting IP phones directly to the internet without using a router or firewall is dangerous as anyone with an internet connection can access the phone’s web interface. If a router has a firewall, it should be enabled.
7. Limit Physical Access to Networking Equipment — Networking equipment should be stored in a secure room or cabinet and accessible only to the IT team.
8. Restrict User Access to Parts of the Phone System — Granting only necessary access to users helps prevent unauthorized changes to the system.
9. Ensure Data Encryption through Your VoIP Provider — Data encryption is crucial to prevent unauthorized access to your data.
10. Educate Users on VoIP Security Best Practices — Educating users on security best practices helps prevent accidental security breaches.
11. Prevent Ghost Calls on IP Phones — Ghost calls are a common issue in IP phones and can be prevented by implementing intrusion prevention systems.
12. Implement Intrusion Prevention Systems — Intrusion prevention systems help detect and prevent unauthorized access to your system.

By following these best practices, you can ensure the security of your VoIP system and prevent unauthorized access to your data.

Cloud VoIP is a key element in any business communications plan, providing both financial advantages as well as elevating corporate operations and appearance. The selection of the ideal VoIP phone type for every user must be carefully made amidst an array of mobile and desktop options.

Before you dive into any Cloud VoIP implementation, it’s essential to consider the types of handsets necessary for your business, as well as if adequate infrastructure is available at each installation point. The two main handset choices are soft phones on smart devices or physical units that connect to a wired or WiFi network. Ultimately, the best option depends on what will provide optimal service and scalability for your specific needs.

Networking and Power

For VoIP handsets to make and receive both internal and external calls, they must be connected to the digital business network. To do this, a Cat5e Ethernet cable or better is needed for cabling connection. Plus, with the recent introduction of WiFi compatible adapters and handsets in the market today, you can now set up your own wireless environment too!

For those with a smaller business, VoIP can be hosted in the company’s own infrastructure or as an external Cloud VoIP provider. If your requirements are even more modest, then you could utilize a PC connected to the network and running some simulated PBX software.

Handset Selection 

Handsets vary greatly in design and aesthetics. From the traditional physical device attached to a desk or wall, to SIP technology allowing your smartphone application to simulate a telephone – there are countless options for you choose from!

From a fairly simple keyboard to an advanced, programmable model with integrated video-conferencing displays and audio without manual operation—the selection of physical handsets depends entirely on the user’s individual needs as well as their professional requirements. Making such an informed decision should be done during pre-installation planning.

Mobile Users

Professionals such as managers and executives often require consistent communication; this could pose a difficulty in a large space, like an educational institution or factory. Fortunately, VoIP systems equipped with the SIP protocol make staying connected much simpler.

Smart phones can access the VoIP phone system through an app that mimics a desktop handset and communicates with the system using SIP protocols. This means that once connected to your business network, in most cases via WiFi, employees are able to use their smart device exactly as if it were their office telephone.

Using an Integrated Communications Strategy that often contains VoIP offers various benefits to organizations, such as cheaper long-distance and international calling rates, improved customer relations, and better performance in the workplace.

VoIP has many advantages, but it can cause problems if not used correctly. Here are some issues you may come across.

Routers and Switches

A malfunctioning VoIP system could be The issue might lie with your router or switch. To rule this out, ensure correct configuration to support VoIP on both devices as well as updated Firmware versions. Another potential culprit for poor VoIP quality is an improperly configured switch port not allowing VLANs.

Outdated routers can often cause compatibility problems and poor performance. To see if this is the case for you, try resetting your router. It might not work, but it’s worth a try.

Bandwidth

To ensure optimal VoIP performance, make sure you have enough bandwidth. Network congestion can cause problems, soTry to avoid it if possible. If the problem only happens sometimes, see which application or service requires a lot of bandwidth during those times.

Include bandwidth monitoring as a standard network management task to identify and resolve connectivity issues quickly. Sometimes, though, a network issue originates from your ISP (Internet Service Provider) or another external factor beyond your control.

Desktop Problems

One of the most common VoIP issues is an echo. It happens when you have your handset volume turned up too high and the microphone picks up the sound coming from the earpiece, and then plays it back.

The most prevalent solution is to lower the sound on both ends. Nevertheless, this does not always fix the issue, and thus another option is to use a headset. Although headsets have their own disadvantages like ergonomics since they can be worn for extended periods of time.

Another possibility is that the problem lies in user training—or lack thereof. “It’s just a phone” has been used as a reason to skimp on training budget, but VoIP systems are complex and comprehensive solutions. Therefore, proper education is key to taking advantage of all benefits.

Many people use the terms VoIP and IP telephony interchangeably, but are they actually referring to the same thing? Are there any technical or non-technical distinctions between them?

IP Telephony

IP telephony uses digital concepts and technologies to improve communications systems. Furthermore, VoIP or voice over internet protocol is a term used to describe using the Internet for long-distance calls instead of the more costly PSTN service.

VoIP

VoIP technically speaking, is a standards-based method for transitioning voice traffic to digital communications. The network might be private or internet-connected for long-distance and worldwide communication as VoIP falls under the IP telephony category.

Some of the most popular VoIP programs at a domestic level include Skype and Whatsapp. They are often used to provide non-toll-free calling alternatives instead of regular PSTN/cellular phone calls.

Implementing IP Telephony and VoIP

IP telephony does a lot more than voice communications and regular phone equipment. Even though the handsets are VoIP phones and VoIP is the protocol that manages the voice traffic, IP telephony covers a larger area than just voice communications. Installing this type of system has different requirements as well.

To digitize a telephone network means to change it over from an analog signal to digital. This, like any other business-based endeavor, requires you to establish what you wish to achieve and the benefits your company will experience by going digital. Without defined goals, you won’t be able gauge if the process was successful.

The requirements for VoIP are minimal. You don’t need much beyond a smartphone or desktop computer with the installed software. Apps such as Skype or Whatsapp will do the trick and once you have an internet connection, you’re all set!

Individuals and businesses have enthusiastically embraced VoIP Solutions. It is simply because the major cost savings in moving from a tolled PSTN network to toll-free internet connections for some people. There are, of course, other advantages in terms of improved operational procedures and customer service standards.

A popular inquiry is whether VoIP Solutions make a beneficial contribution, especially in the educational sector. The answer is a confident YES, and it’s not just for education. Any campus setup with multiple buildings or sites will profit from them.

VoIP on Campus

Schools and Universities, like any other enterprise, are managed with an HR department, Financial team, Procurement officers, and other essential business functions. These teams are supported by education-specific features such as curriculum development and student management. Other services that may be offered include postgraduate support; residence management; meal bookings; among others.

Call Management

Every educational institution’s success depends on its students. At the beginning of every academic year, there is a flurry of activity as old and new students are registered and put into courses. VoIP can provide advantages in various forms:

• With calling/hunting groups, promptness is key to handling incoming calls. Additionally, Pickup allows for staff members at unattended desks to take calls when the intended recipient is absent.
• With SIP technology, VoIP calls can be made through a smart device app, which is useful for times when you’re on the go and need to be contacted. If you’re within campus WiFi range, implementing this system guarantees that staff are always contactable.
• Occasionally, an event must be broadcast in several locations. A typical example is a graduation ceremony taking place on one campus that is streamed to all other campuses. For graduations completed remotely, this is becoming more significant.

Collaboration

• Students are increasingly using social media to access their e-learning courses and materials. For many students, having a smart device and being able to connect to social media is essential for their education.
• Many professors are now using WhatsApp and other similar platforms to communicate with their students. Additionally, students are submitting assignments online and working together on social media for assigned tasks.
• In many nations, there are educational networks that link primary and secondary schools, as well as colleges and universities. Over that network, academic and non-academic personnel can interact with each other easily on a one-on-one and group basis using VoIP and video conferencing.

Safety and Security

Many businesses are concerned about safety and security. Students and personnel can utilize an emergency contact on their smart device if SIP and VoIP are linked to a WiFi network. If they need help, this number is readily accessible to call for assistance.

Utilizing VoIP Solutions in an educational setting is a smart move that will benefit the school in more ways than one. In addition to saving money, it also improves communication among staff and students, as well as creates opportunities for the institution to partner with other schools.
