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

by Paul Kratz

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.

Why Media Gateways Anymore?

by Jim Machi

Nov 7, 2017 9:12:00 AM

This past summer, I wrote a few blogs relating to older technologies such as PSTN, SS7, Fax, etc.  At Dialogic, part of what we do is live in the world of bridging these older technologies to today.  The older technologies live on longer than any of us might imagine, and we have customers who still buy these technologies for various reasons – all revolving around the networks still being used, no matter how much we hear about LTE. And thus, there is business for them and thus, us to be had.

The Importance of SS7 to SIP Interoperability

by Jim Machi

Oct 24, 2017 9:03:00 AM

SIP endpoints such as softphones / headsets used for IP based enterprise VoIP calls,  for WiFi calls, and for calls from third party communication apps such as WhatsApp, Viber etc. are becoming the norm. And with continued integration on the phone side (see Apple CallKit), these will continue to proliferate.

SIP Trunking Options for Mixed Networks

by Jim Machi

Sep 19, 2017 9:44:47 AM

Back in June, I wrote a blog about using Gateways for SIP trunking if there are PSTN lines inside the enterprise.  And this makes sense for sure given 40% of enterprises are still PSTN on their internal networks.

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.

What Should the Next Generation SBC Be Able to Handle?

by Jim Machi

Jul 11, 2017 9:00:00 AM

It’s strange to be writing about a next generation SBC, given that it seems only yesterday that SBCs came to the fore.  But alas, SBCs have been around for over 15 years now. The original SBC functions that were there to support peering for IP – IP networks, such as connectivity in the form of IPv4-IPv6 interworking, NAT traversal, and SIP protocol translations and security in the form of DoS support, toll fraud, signaling encryption, and packet protection are still very much important, but the SBC has been asked to do more these days.  So if you have an SBC from the “old days” it’s likely not pulling its weight.

SIP Trunks and Whaaaat???…Gateways…but not SBCs?

by Jim Machi

Jun 20, 2017 9:03:00 AM

Back in March, I wrote a blog about the PSTN sunset. But in reality legacy technologies are still in use.  I know this since we still sell them. Certainly, IP is growing and SIP Trunking is growing, but for most companies this means a gradual transition, not a full scale wipeout of existing technology.

Is It Over for SMS?

by Jim Machi

May 2, 2017 10:13:58 AM

According to some research from the GSMA, all is not lost with the SMS battle against the IP messaging services. With WhatsApp, Facebook Messenger, and WeChat at about 1 billion monthly active users, it would seem that it’s just a matter of time before SMS becomes extinct.  However, according to this report, “SMS retains its lead in markets that were early adopters of unlimited SMS bundles,” which makes sense.  Start using it and you get used to it, especially if there are no extra charges.

What does this mean for service providers?
