Cabovisao offers voice service to more than 160,000 customers

Cabovisao, the cable operator in Portugal, with more than 770,000 homes passed, has deployed the Nuera VoIP gateway to offer telephone services. Nuera’s RDT-8v broadband access gateway enables Cabovisao to leverage their Class 5 circuit-switched infrastructure to offer voice services over an IP network.

Currently, Cabovisao offers voice service to more than 160,000 customers using Constant Bit Rate (CBR) technology. Cabovisao has implemented bi-directional HFC network and national fiber-optic backbone in Portugal for the delivery of cable television, high-speed Internet access, telephony and data transport services. Nuera’s technology helps Cabovisao bundle these services over an IP network.


Sylantro and Convedia to deliver IP centrex solutions

Sylantro and Convedia have announced completion of interoperability testing of their respective products, along with a partnership to deliver IP Centrex solutions for telecommunication service providers. The integrated Sylantro/Convedia solution is currently in trials in incumbent service provider networks in both Asia and North America.

Sylantro has utilized Convedia’s SIP control interface to achieve interoperability with Convedia’s media-processing features including announcement playback, VoiceXML script processing for IVR, advanced audio bridging, media transcoding, and audio recording and playback.

The SIPindex Parameter

Why is it every time we try a new SIP device we have to input our SIP settings all over again? Should there not be an SIP Index of sorts that allow us to input the settings once and those settings are used with every SIP device I make use of?

This concept becomes even more troublesome when you compound this issue by having multiple SIP networks available through one device, not unlike Xten’s softphones.

Enter the SIPindex parameter and the SIPindex Draft RFC. Soon there will be a draft RFC put forth to the IETF by Robin Raymond [Xten CTO] and Erik Lagerway [myself] which will lay the groundwork for a new SIP Parameter, the SIPindex parameter. This index will house profiles of every SIP user and will distribute those profiles to soft and hard IP communication devices all over the world.

Instead of entering your settings every time you will be able to simply point your device to a central URL to fetch your SIP settings.

More on this later.


The Rise of Free Telephony

Free telephony services are popping out of the woodwork. I believe you will see some serious changes in the way the incumbent providers roll out new services due to the influx of free IP voice communications.

Already we see the proof in this by the recent actions of some of the largest voice providers on the planet.

I think this trend will continue and grow, putting even more pressure on the telcos to follow suite. They will most certainly continue lobbying the regulators trying to convince them to impose restrictions but alas, this is free service we are talking about here. What will they regulate next, our freedom of speech?

Keep an eye on providers like and, they will shape the industry for years to come.


The VOIP Revolution

The VOIP Revolution

It’s showdown time once again at the Federal Communications Commission, and the stakes could be significant for consumers and big businesses, as major telecom providers and upstart technology firms square off over whether Internet phone calls should be regulated in the same way as traditional phone services.

Today the FCC will host a forum on Voice over Internet Protocol service — VOIP for short.

The Wall Street Journal set the stage for the forum in a Friday article, reporting that VOIP “could radically transform the $300 billion telecommunications industry and is renewing doubts about whether the Internet should remain regulation-free. Sending phone calls over the Internet … is one of many technologies moving more quickly than regulators can react. … In some such calls, traditional phone lines are effectively cut out of the process. That strikes fear among Bell phone companies such as BellSouth Corp. and SBC Communications Inc., which charge fees when traditional phone companies such as long-distance providers use their lines to complete calls (long-distance companies usually don’t own the lines that go into customers’ homes or offices). The Bells must provide service to everyone, and remain heavily regulated in areas from pricing to emergency 911 services.”
