Successful Disaster Recovery Tips for VoIP Systems

By CIOReview | Tuesday, September 13, 2016

The internet has created a revolution, especially in the telephonic system by allowing users to call, video call and chat anywhere across the world. The concept of Voice over IP (VoIP) emerged in the late 90s to transport multimedia over the IP network. VoIP offers an alternative to telephone system by routing digitized voice signals over IP networks including company intranets and public internet.

What is VoIP?

Voice over Internet protocol (VoIP) is a technology that allows making voice calls or telephone calls by employing a broadband Internet connection instead of a regular phone line. VoIP services use a traditional phone with an adapter, while others only work via a computer. It also offers significant benefits to customers including cost savings, phone and service portability, and integration with other applications.

Emerging issues over VoIP

The first and foremost issue is inadequate connection; VoIP depends on user’s broadband connection, if the connection goes down, it directly affects the phone line as well. The connection quality is another major concern in the VoIP; poor quality results in a bad VoIP experience. On the other hand, some VoIP devices may not work during power outages and the chance of offering a back-up power by the service provider may be minimal. Not all VoIP service connects directly to the emergency services. In addition, VoIP providers also may not offer directory assistance and white page listings. These emerging issues in the VoIP have led to a robust disaster recovery in the VoIP systems.

Benefits of VoIP technology

The VoIP technology delivers seamless connectivity across the world. Here is the list of robust benefits that VoIP offers for the users looking for implementing efficient and vibrant technology.

• Cost savings:

VoIP aims at delivering maximum benefits to the user at lesser costs. Users can make long distance phone calls comparing to the telephonic versions. Looking at the company front, VoIP also reduces cost for equipment, lines, labor, and maintenance. The service providers enable VoIP to reduce the cost of service deployment by using the same communication infrastructure for different services.

• New communication services:

The VoIP technology has taken over the basic communication services (phone, fax) with latest technology. The technology includes users to check out friend’s presence: if they are online, offline or busy, and further send instant messages, make voice or video calls or transfer images.

• Phone portability:

Using robust IP connectivity, the mobile users can use the same number virtually everywhere. Many business people use the same IP numbers and carry their IP phones while travelling.

• Service mobility:

The service mobility in applications is available to the user, wherever he goes. The services include call features, voicemail access, call logs, security features, and service policy.

• Integration and collaboration:

The users can also leverage special features of integration and collaboration with other applications such as email, web browser, instant messenger, and social-networking applications.

Tips for successful disaster recovery in VoIP

Leveraging the internet as an infrastructure of voice communication, VoIP systems often faces number of security issues. Tackling VoIP against disaster involves robust tips and recommendations. Firstly, the key for a successful disaster recovery is to ensure that VoIP phone system protection is included in the network’s firewall setting. Users can also find “VoIP- aware” firewall through any VoIP Managed Router available. User carrying phone while travelling should also make sure that VoIP phone system is implemented before installing the firewall. The firewall should also support common VoIP protocols including H.323, Session Initialization Protocol (SIP), and NAT.

Secondly, ensure WPA-2 encryption and WPA password security in all wireless networks, so that the employees accessing the VoIP system through personal devices have suitable encryption and authentication necessary.

Thirdly, security plays a key factor in VoIP; preventing security breaches by creating a strong password and allowing IT executives to take control over it. Educating the employees on the best practices and changing appropriate passwords frequently can contribute in preventing security threats. Monitoring and tracking unauthorized conversations by reviewing calls to eliminate abnormalities or spikes is an ideal practice in disaster recovery. It also allows a business to view and identify when the VoIP system is used and by whom.

In addition, the VoIP also delivers seamless telephonic calls without being uninterrupted. One should also make sure that call forwarding rules are reviewed regularly in order to ensure proper routing and calls quality. In addition, enabling monitoring algorithms in VoIP provider can further help in detecting unusual call behavior that may be fraudulent or unauthorized.

Also, technology should be updated to eliminate the need for human intervention. Enterprises should also ensure that during unusual traffic detection, the VoIP provider should automatically shut off service to the monitoring system. This can even help in preventing Toll fraud and international calling.

Enterprise should also join hands with experienced VoIP phone service partner to fortify network security weaknesses. The experienced phone service partner will be able to detect and resolve any malfunctioning in the VoIP, and also will be able to provide stringent backup and disaster recovery services.

Implementing and ensuring these practices can help in shaping VoIP into a more reliable, cost-effective, and scalable technology; based on enterprise needs.

The Future of VoIP:

The acceptance in the VoIP technology is likely to replace the Plain Old Telephone System (POTS) completely in the future. The concept of “maximum benefit with minimum costs” has attracted enterprise in adapting to this new technology. The drawbacks in the traditional telephonic system and the increase in revamped technology have leveraged the adoption towards VoIP to likely increase in the future.
