Telephony denial of service (TDoS) is a type of cyberattack that can be used to disable telephony systems. Similar in concept to a typical data network DoS (denial of service), its purpose is to deny users access to a particular telephony service. In this article, we discuss how TDoS attacks are conducted and what measures you and your telco can take to protect your systems.

The COVID-19 pandemic is impacting businesses around the world. Organizations are being forced to maneuver in a new world of security and privacy issues related to a remote workforce involving hardware and software needs, as well as employee access policies. While working from home may be a new and foreign concept to some companies, the cloud-based tools they use everyday have made it infinitely easier to continue operations and serving their customers with the same level of quality of service, support and communications that their brick and mortar operations have sought to provide.

So, as resellers and service providers of VoIP and uCast services, one of the most critical components in enabling a successful work-from-home experience for your customers (and their customers) is to keep the phone services operating as normally as possible. In this article, we suggest six steps to enabling an effective work-from-home (WFH) environment.

For most organizations these days, WAN connectivity is so mission-critical that investing in a redundant WAN infrastructure is well worth the extra cost and effort. In this article, we explore the available options for WAN redundancy so you can help your customers decide which is the best for them.

In today’s business environment, coordinating teams of people working on a multitude of projects and tasks can become complicated. This is why collaboration tools are so important to streamlining cooperation and increasing efficiency. Yealink has developed a series of products that maintain a deep integration with Microsoft Teams, the software giant’s communication and collaboration platform. Yealink has the widest range of Teams-certified voice and video devices on the market. In this article, we review Yealink's T-series IP phones, certified by Microsoft for use with both Teams and Skype for Business.

Last week, we discussed centralized call processing and its benefits and potential pitfalls. In this article, we’ll examine another type of telephony infrastructure design for multisite enterprises: distributed call processing.

If you have customers that have not yet migrated to VoIP and are thinking about making the switch, this would be a great time to do it. According to the FCC, VoIP telephone subscriptions in the U.S. have been growing at a compound annual growth rate of 10% since 2013, and retail switch access has been declining by 11% annually during the same period. At that rate, VoIP subscribers now outnumber switched access customers, and ISDN connections are quickly sliding into obsolescence. SIP trunking is becoming the standard for PSTN connectivity.

To ensure a smooth transition, start by helping your customers answer these four basic questions to set them up for success.

Part 2 of 2: Cloud communications offer many advantages, but some businesses benefit less than others

In Part 1 of this series, we reviewed some advantages of cloud-based unified communications (UC). Among other things, we emphasized the ease of use, streamlined functionality, and cost savings of this platform as compared with a similar on-site deployment. However, there are situations where cloud-based UC is less advantageous. In this article, we look at the prerequisites for using UC over the cloud as well as some specific examples.

There are several ISPs (internet service providers) that can provide your business with high- and super-high speed internet access. These technologies include Metro Ethernet and Fiber to the Premises (FTTP) and offer speeds from several Mbps to 1 Gbps and beyond – but with a hefty price tag.  

An alternative is the bonding of multiple ADSL/VDSL or cable lines to take advantage of the aggregate bandwidth of these connections while paying a comparably miniscule monthly cost. All that’s needed is a load balancing WAN router like Peplink’s Pepwave Balance 20 Dual-WAN Router.

Designed for small office and branch office use, not only does the Balance 20 router perform link bonding and load balancing, but it also offers an impressive array of additional features.

As one of the biggest expenses of any business, telecommunications solutions should be both reliable and cost-effective. One telephony network design aspect that can provide both is the direct connection of the IP phone system to a mobile network.

Here we explore two ways to do this, either of which not only achieves cost savings for the company but also enhances reliability by providing an additional redundant and overflow route.
