Dialogic and 5G roaming – Staying Ahead of the Curve with HTTP/2

My niece is volunteering in the Peace Corps in West Africa. When her younger sister learned that the 110V hairdryer she wanted to send would not work in the 230V environment in Sierra Leone, she asked an inciteful question, “How come her cellphone works?”. I am a telephony sales engineer by trade, and I was born and raised in South Africa, so naturally she turned to me for an explanation.

Session Border Controller – What is it and why do you need one?

by Ofir Shalev

Jul 30, 2019 9:00:00 AM

Session Border Controller (SBC) is a network device that secures voice over IP (VoIP) infrastructures while providing interworking between incompatible signaling messages and media flows (sessions) from end devices or application servers. SBCs are employed in enterprise infrastructures and any carrier network delivering commercial, residential, business, fixed-line, or mobile VoIP services. They are typically deployed at both the network edge and at carrier interconnects, the demarcation points (borders) between their users and other service providers.

STPs keep going

When I’m meeting with customers, usually I do a brief overview of our product line.  While we have all the cool software and NFV and AWS based network infrastructure, we also have some more traditional products.   And when our customers find out we sell Signaling Transfer Points (STP) and other SS7 products, they sometimes are astounded these nodes are still being sold.

Considerations for Cloud Based SBC's, Part 2

by Jim Machi

Jan 3, 2018 5:00:00 AM

 

As Infrastructure as a Service (IaaS) takes hold, which means there are key communications infrastructure nodes running your business that are now out of your physical control because they are running in the cloud, the ability to understand how these nodes are performing is more critical than ever.

Considerations for Cloud Based SBCs, Part 1

by Jim Machi

Dec 19, 2017 10:30:00 AM

As more and more enterprises are turning away from CPE based equipment to cloud-based services, Infrastructure as a Service is becoming more prevalent.  One of the key infrastructure nodes that will be required on these enterprise IP-based virtual networks will be SBCs.  These SBCs will still be required to serve their traditional roles including securing the network border and media transcoding for the cloud-based services, such as Unified Communications, that they support.

2018 (likely wrong) Predictions

by Jim Machi

Dec 12, 2017 11:00:00 AM

Last year, I refrained from making any telecom predictions.   And no one complained.  And this year I was content to continue down that path.  However, I got an offer I couldn’t refuse regarding making 2018 predictions for the Fast Mode 2018 Trends and Outlook, so I did. The full article is linked below.

Network Slicing – An A La Carte Network Service in 5G?

by Jim Machi

Oct 17, 2017 9:16:00 AM

I’ve been meaning to write about network slicing for a while.  When 5G was first being written about, network slicing was one of many hot topics about 5G. 5G, after all, is going to solve every potential mobile cellular issue we’ve ever come across. At least it seems that way.  And network slicing represented a certain nirvana.  By the way, 5G will be THE ANSWER until 5G specs are done, and it starts to get deployed, and then the hype will start for 6G.  And then we’ll have a new answer. Until then, let’s talk about how great 5G is.

MVNO’s Need Their Own Infrastructure To Differentiate

by Jim Machi

Aug 8, 2017 10:11:50 AM

Mobile Virtual Network Operators (MVNOs) are increasingly investing in their own infrastructure. Why?  Because running on someone else’s mobile network and trying to differentiate via marketing / branding isn’t good enough anymore.  So MVNO’s are putting in some of their own infrastructure to use with the host network to create functional differentiation in addition to the marketing differentiation. 019 Telzar in Israel has recently done this, and it resulted in a 50% increase in its customer base in 5 months. Mobile Virtual Network Enablers (MVNEs) have also emerged to supply the infrastructure differentiation to the MVNO’s, so the MVNO itself doesn’t have to invest in the infrastructure.

Future of the Multifunction Peripherals (MFP)

by Jim Machi

Aug 1, 2017 9:01:00 AM

MFP’s (Multifunction Peripherals) take up valuable real estate in an enterprise office environment.  As the world goes more digital and more green, it stands to reason that there will be less printing, less scanning, and less faxing. But they will remain essential to the office for when you do need to print, scan, or fax. So, what can you do with them to maximize the real estate?
