VoIP & Tell
WebRTC promises to disrupt not only the telecommunications industry but the OTT establishment too, by making real-time audio and video ubiquitous and free on the web. Crocodile RTC Technical Director Peter Dunkley explains what they’re doing in this session.
There are myriad factors impacting the broad roll-out of HDVoice. Does anyone support HDVoice over LTE in mobile space? Does anyone actually enjoy HDVoice on T-Mobile? Will CableCo’s leverage their strength in residential phone service to deploy HDVoice in a big way? We’ll go to the man who makes it his business to know with these questions and more.
And of course, we will walk-the-walk as we talk-the-talk, conducting this call in HDVoice via ZipDX.

What is DNSSEC (Domain Name System Security Extensions) and why is it important enough to send the likes of Mr. York around the globe? This and more Friday on VUC. The graphic below is from an analysis by DNSViz.
How do you know that you are in fact connecting to the correct VoIP system when you initiate a call or launch a client? What if someone redirected you to a different server? How would you know? Are there ways that we can improve the security of VoIP/UC systems? We rely on the Domain Name System (DNS) to resolve domain names to IP addresses and connect our computers to the correct destinations – but there are some weaknesses there that can be exploited. The “DNS Security Extensions” (DNSSEC) provide a mechanism to cryptographically ensure that the information you are getting out of DNS is the same information the operator of a domain put into DNS. A companion protocol, DANE, provides a mechanism to publish TLS/SSL certificates (or fingerprints of certificates) in DNS and add a stronger layer of trust to certificates. Both DNSSEC and DANE can potentially have a role to play with VoIP/UC.
In this VUC episode, Dan York will explain what DNSSEC and DANE are all about, how they work and will open a discussion about how they might be used within VoIP/UC to strengthen the security of communication. He’ll also talk about the DNSSEC support included in both the latest version of the Jitsi softphone and the Kamailio server. He’s looking for feedback and really just trying to raise questions around how all this work happening in the DNS area could benefit what we’re doing in the world of VoIP / UC / RTC / whatever. What could we do in VoIP if we had a global PKI we could use? Please come with your questions and ideas.
Ken Rice explains how, with Raspberry Pi, FreeSWITCH, hardware hacking, and port audio, we can build our own hard phones. Also updates on the latest FreeSWITCH news and possibly a scoop on something brand new. FreeSWITCH is a scalable open source cross-platform telephony platform designed to route and interconnect popular communication protocols using audio, video, [...]
