Understanding SD-WAN and Edgewater’s Solution for the SMB
Posted by Danielle Bucella on 13 August 2018 01:59 PM

Software-defined wide area network solutions, commonly referred to as SD-WAN, are exploding. Enterprises began expressing specific concerns and needs for networking, which could only be met by this technology. In turn, SD-WAN growth has been monumental and sources predict that SD-WAN infrastructure and service revenue will reach over $8 billion in sales by the year 2021. As businesses begin to deploy 3rd platform technologies to achieve digital transformation and public cloud-based SaaS continually increases, we will see SD-WAN rise steadily. With that said, it is imperative to understand what SD-WAN is and what SD-WAN solution is best for the SMB versus the enterprise.

What is SD-WAN?

Simply put, SD-WAN is a technology that was specifically designed to improve network performance of small to large enterprises. Traditional enterprise WAN had many pain points associated with it, including data throughput, cost structure, resiliency, and application performance. WAN is used to connect different networks to a central network. Before, WAN connections relied on technology that required special hardware. What SD-WAN does is that it moves network control into the cloud and relies instead on a software approach. It provides enterprises with a flexible, open, cloud-based technology versus needing expensive WAN technology, hardware, and fixed circuits. SD-WAN technology is generally applied over large geographical areas

SD-WAN has also been able to replace or augment multi-protocol label switching (MPLS), which was the standard technology for secure corporate WANs. MPLS has a handful of negatives attached to it, including the requirement for expensive dedicated access circuits, long implementation timelines, and route inflexibility for off-net traffic. Because of its associated downfalls, many have searched for an alternative solution.

SD-WAN addresses these pitfalls by utilizing Software Defined Networking (SDN). SDN separates the control plane, which manages where data goes, and the data plane, which is the actual payload. It does so by using a cloud-based controller for management. General purpose access circuits can then create secure WANs and costs can be driven down. Also, by using commodity access, there is faster turn-up of new sites, greater performance in corporate data routing, and better resiliency and uptime.

A Solution for the SMB

The SMB is generally not the typical consumer of MPLS because they usually only have one location or a few sites. But, these customers still value performance of their applications and resiliency and want to make sure they’re always up-and-running. Enter Edgewater Networks’ approach to SD-WAN, which was designed specifically for the needs of the SMB. Edgewater’s solution focuses on four core components: application-specific priority, multi-link performance, stateful SIP transfer, and survivability.

  • Application Priority: It is important to ensure that your critical data traffic is being prioritized over less important routine traffic. This has caused a reoccurring issue for businesses. A network sees less critical traffic in the same way as more important traffic, leading to congestion issues. Edgewater’s SD-WAN solution provides application-specific priority, allowing businesses the ability to segregate critical traffic over routine. In turn, this creates a better customer experience.
  • Multi-link Performance: One common router feature at the edge, referred to by Edgewater as WAN Link Redundancy (WLR), is the ability to move traffic from one link to the next in a failure condition. WLR moves all traffic from the primary WAN link to a secondary when there is an outage. It will then be moved back once the outage is restored. Multi-link performance improves upon WLR. Instead of just moving traffic during an outage, multi-link performance moves traffic based on degradation (i.e. reduced WAN link performance that impacts critical business applications). The SP can determine what gets moved and under what conditions. Once applications requiring prioritization are determined, routing decisions can then be made. Using both latency and hop count measurements, the EdgeMarc will evaluate link quality, rerouting traffic if degradation and/or link failure is determined. When multi-link performance is combined with application-specific routing, the SP can completely control the applications that have priority, determining how they should behave in various levels of WAN degradation or outage.
  • Stateful SIP Transfer (SST): SST is a combination of application routing priorities (SIP) and multi-link performance to manage SIP voice sessions across multiple WAN connections. SST has a multitude of capabilities, including: the ability to move SIP sessions from one WAN connection to the other (if degradation or outage occurs), the ability to move individual or all SIP sessions based upon the level of degradation in degraded conditions, SIP sessions stay active during transfer between WAN sessions, and continued monitoring of WAN links and SIP sessions being moved to primary connections if conditions warrant (the session would stay active)
  • Survivability: While not an SD-WAN specific feature, survivability increases resiliency and business continuity functionality to the SD-WAN solution. Survivability includes failover functionality to analog trunks, as well as limited PBX functions in outages (station-to-station dialing, hold, transfer, park, and conference).

Benefits of Edgewater’s SD-WAN Solution

Edgewater’s SD-WAN solution targets the SMB specifically, so it addresses a different set of customers’ needs. This makes Edgewater’s approach quite different in regard to routing and pricing. For a typical SD-WAN solution, routing decisions are made by a cloud-based decision engine; however, with the Edgewater SD-WAN solution, all routing decisions are made at the device (EdgeMarc) level. Pricing is also different. Typical SD-WAN solutions leverage cost savings that are associated with MPLS displacement. The Edgewater solution has been aggressively priced, though, to fit an SMB budget.

There are many customer benefits to choosing the Edgewater SD-WAN solution. End customers will experience:

  • Better voice quality
  • Higher overall quality & resiliency
  • Better application performance

Service Providers will also see a handful of benefits on their end, including:

  • Fewer customer issues
  • Greater CSAT
  • Ability to upsell resulting in higher revenue
  • A user portal that provides better insights to the customer on network performance

Trade Up to SD-WAN Program

If you possess a legacy Edgewater intelligent edge or other qualifying SBC, it is time to transition to an SD-WAN capable device. With Edgewater’s Trade Up to SD-WAN Program, it is easy to receive a new device. Simply sign up for Cloud2Edge and purchase one of Edgewater Networks’ SD-WAN capable devices. You will then receive a great rebate for trading in your old device. For more details on the program, which only lasts for the remainder of 2018, contact your 888VoIP representative at 888-864-7786 or [email protected]

6 Reasons Why Customers Love Yeastar Multisite Interconnect
Posted by Danielle Bucella on 24 July 2018 03:20 PM

Yeastar Multilink Interconnect

Businesses are gravitating away from the traditional model of housing all employees and functions at one single location. Instead, many are relying on smaller branch offices in various geographical locations, as well as home-based remote workers. Work is no longer about one single location and activity is being done anywhere and everywhere, so PBX manufacturers had to come up with an efficient solution to connect dispersed phone systems.

Yeastar, an internationally known manufacturer of PBX and gateway solutions, has developed multiple options to assist businesses in connecting remote employees. One top option is to network S-Series VoIP PBXs at different locations, which can be interconnected by utilizing the built-in Multisite Interconnect feature. This feature allows simple interconnection of S-Series PBXs in different offices. PBX customers are flocking to this new feature, as it offers immense benefits over the traditional inter-branch connection via SIP trunking.

Here are six of the major reasons as to why customers are turning to Yeastar Multisite Interconnect:

  1. Explicit Role-Based System: The role-based system allows you to maximize the simplicity of a multi-office network by designating one “headquarter” PBX and multiple “branch office” systems. The “headquarter” PBX will work as the pivot, collaborating with all the other systems. There will only be one link between a branch and the headquarter, which will allow the branch to connect to all other offices. This will simplify communication and make management of converged voice much easier.
  2. Secure Interconnection: Yeastar Multisite Interconnect sets up an extremely secure network. General access rules are configured in the “Firewall Rules” module. IP Exclusion Rules are set up on each branch profile, which ensures that the network will be protected from any attacks. Since there is also no port forwarding required at any branches, that potential security risk is reduced, if not eliminated.
  3. Designed with Innovation in Mind: This feature was designed exclusively for the Yeastar S-Series of VoIP PBXs, applying to all models in the series. It was crafted to enable easy interaction between S-Series PBXs that were deployed in different offices. Call flow is automatically smoother, deployments are quicker, and maintenance is easier. Customers now have an additional choice from Yeastar for branch office solutions.
  4. Easy Dial Plan: Quite possibly the most apparent benefit of Yeastar Multilink Interconnect is direct dial and seamless call transfer between different locations’ extensions. No matter what site you’d like to reach – extension, conference, ring group, or queue – you can simply dial the number directly. Each system occupies a unique first dialing digit. This ensures a smoother flow of communication & also eliminates the need to remember different prefixes.
  5. Lowered Costs: Internal calls are completely free, even if you’re contacting a different site. You’re not just saving money there, though. Traditional SIP trunking brings about many of its own costs, including the need to purchase static public IP addresses for each site and annual fees in the thousands. With Multisite Interconnect, you do not need to rely on expensive SIP trunks. You only need one static public IP address for the entire system!
  6. Simple Configuration: When you use SIP trunks, your corporate network setup becomes quite complicated and the process convoluted. Headaches arise when calculating how many SIP trunks need to be configured or determining the required outbound call routes. When using Multisite Interconnect, you just register each branch’s phone system to the headquarter PBX. You do not need to create any trunks or call routes. You also do not need to worry about a static public IP address or port forwarding at the branches. A network of six offices can be set up in just minutes.

5 Considerations to Make When Switching to a Cloud PBX
Posted by Danielle Bucella on 25 June 2018 04:38 PM

Cloud computing is the wave of the future, and inevitably, many technologies are moving to the cloud. For a myriad of reasons, it is appealing to switch to a system or product where data is stored and transferred over the Internet. This eliminates the need for users to purchase certain computers or hardware devices. VoIP technology is included in this migration. Initially, calls were routed by a physical on-site PBX, which could be costly, time-consuming, and sometimes inefficient (thus the transition to a cloud offering). The cloud PBX allows users to access the same capabilities and features they would normally receive from an on-premise PBX but eliminates the need for pricey equipment. Also, a VoIP provider will handle all of the routing services and support, instead of having in-house technical support/IT address this task.

While there are many attractive reasons and substantial benefits to switching to a cloud PBX, there are a few considerations that businesses must make if they have decided to switch from an on-premise PBX to the cloud.

Costs & Budgets

What is a business’ budget and what options will work within that? Cost is one of the big factors to assess when upgrading equipment and technology in an office. It is important to look at the different costs that will be associated with the cloud PBX solution, including setup and support costs. Also, businesses must decide if they are going to be upgrading phones or will need to purchase new compatible devices. While these expenditures must be part of the cost analysis, remember that initial start-up and/or equipment costs generally are a one-time expense.

Where are the cost savings? PBX phone saving studies show that cloud PBX systems can save companies up to 50% (in comparison to other PBX solutions). Cloud-based phone systems are known to have relatively limited upfront costs. Additionally, the need to install, maintain, reconfigure, and upkeep a premise-based PBX, which can lead to unforeseen future costs, is removed from the equation. Cloud solutions also have a tendency to have low set-up costs, call rates, and subscription fees. When completing a cost analysis, do not forget to include the monthly Internet service fee.

Business Needs & Feature Sets

What are the overall business and associate-level needs? It is imperative to assess whether or not the cloud solution comes with all the advanced features (or more) that an on-premise PBX would have. Ask if the solution has all the management capabilities needed, such as import/export of extensions, troubleshooting, and provisioning. Does the business rely on a third-party chat and collaboration program (Slack, Teams, etc.) or does the cloud PBX need to have a chat feature built-in? What security features are a must-have for an organization? It is not safe to merely assume that all cloud PBX offerings are the same, so feature needs should be outlined and then compared with feature sets.

Some of the top key features include:

  • Cloud PBXBusiness Features: Blacklist/Whitelist, Custom prompt, distinctive ringtone, music on hold, one-touch recording
  • Call Features: Attended transfer, blind transfer, call detail records, call forwarding, call monitor, call parking, call routing, caller ID, conference, DND, queue, speed dial, SIP forking, video calls
  • Management: Backup & restore, import/export extensions, multi-level user access, phone provisioning

Multi-Locations & Branch Offices

Does a business need a multi-location solution? If a business spans different geographical areas and is not contained in one location, it makes sense to gravitate towards a cloud PBX. Many cloud PBX options can connect employees on the opposite sides of the globe, offering all employees access to the exact same features. Easily utilize these options to transfer calls between different offices. One other consideration is to assess the cost of long distance calling, which may already be rolled into the package price.

Access on Mobile

One cannot ignore the fact that business extends outside of the four walls of the office. A quality cloud PBX solution will possess the capability to fully function on a mobile device. This is perfect for those employees who have home offices, telecommute occasionally, or even travel frequently. To ensure that this is possible, choosing a cloud PBX with a comprehensive mobile client is a must. In addition to calls being properly routed to mobile devices, a mobile client needs to offer full access to all features.

Internet & Networking Requirements

When setting up a cloud PBX system, determine whether or not the current Internet connection speed is high enough, both up and downstream. Also, check that all basic networking equipment is up-to-date (routers and switches). Ensuring a high level of call quality can be done by having a QoS-enabled Internet connection. Certain equipment, like an Edgewater router, can prioritize your traffic over data.


For the Solution Provider or Reseller

While you may not need to make these considerations since you’re in the role of seller, your customers still need to. It is imperative to understand your customer’s wants, needs, and current pain points to match them with the best product. Find out what a customer’s problem is, provide help them information on how to resolve this issue, and assist them in evaluating the alternatives. Understanding the process your customer is going through is going to ensure that you are helping them make the best purchase decision.

Before choosing the cloud PBX solution that is going to be an ideal fit for your customers, it is best to consult with a VoIP expert. They can work with you to determine what solutions will match with your customers’ needs. The team at 888VoIP specializes in everything VoIP, including on-premise, hosted, and cloud PBX solutions.
