QoS for VoIP networks: IntServ versus DiffServ

Posted by Daniel Noworatzky on Oct 17, 2018 10:48:00 AM

Your customer using a legacy phone system decides to switch to voice over internet protocol (VoIP). They install an IP PBX and buy some IP phones. Great, they’re all set, right? Wrong. Without configuring their data network for quality of service (QoS), they will experience a severe deterioration in voice quality and may regret making the decision to switch. Yes, the IP PBX and the IP endpoints will already be configured for QoS. But what about other parts of the network like the pre-existing routers, switches and firewall? All it takes is one missing link for the whole system to be compromised.

QoS is a big topic. In this article, we’ll look at two main approaches to QoS: IntServ and DiffServ, their strengths and limitations, and when to use which one.

How to set up centralized call processing in a multisite enterprise

Posted by Daniel Noworatzky on Sep 26, 2018 3:53:00 PM

Enterprises with multiple sites have a variety of options when it comes to their IP telephony infrastructure. Which setup will best meet their needs depends on the answers to questions such as:

  • Where should the call processing take place?
  • Where should calls to the PSTN exit the network?
  • Where should incoming calls connect to the corporate network?

These decisions depend on the nature of the underlying network infrastructure that will carry the IP telephony services, as well as other considerations such as the location of the remote sites, the dial plan, and cost.

In this article, we discuss the centralized call processing model and how to avoid common complications with its deployment.

The 3 most common hybrid deployments for VoIP-to-analog solutions

Posted by Guest Blogger on Aug 1, 2018 3:54:00 PM

By Brian Van Meter, Community Marketing Specialist, Grandstream Networks* 

Voice over IP delivers major improvements to traditional communication networks, and as a result legacy analog phone systems are on their way out. Ten years ago, 80% of homes had landlines, but today that number is down to 43%— and businesses are following this trend, as well. However much VoIP is becoming the go-to technology for communications, it is important to acknowledge that certain markets cannot fully convert to a total VoIP solution. Not recognizing this could lead to loss in potential sales against competitors. In these situations, a hybrid VoIP network can help deliver the flexibility and power of an IP solution while catering to the restraints of your customer. Below are some of the most common situations and their solutions.

Worker overwhelm and the demand for UC

Posted by Daniel Noworatzky on Jul 18, 2018 3:48:00 PM

We speak a lot about unified communications and how network convergence allows it. Getting your customers migrated to VoIP is the first step to introducing them to unified communications (UC). Once that is established, they will be much more likely to embrace UC if you can show them the business problems it can help solve.

In this article, we look at some of the key drivers of demand for UC, which you can keep in mind when selling systems upgrades to your customers.

But SD-WAN can do wonders for many types of companies – even a single-site business located in a remote area with an unreliable internet connection. If you work with a company that fits this description, SD-WAN can resolve a lot of their VoIP issues.
