I came across a news item reporting on a new VoIP provider, efonica. Normally this would not have been noteworthy, but the company claimed that it uses a new (five years to develop, mind you) P2P architecture. Naturally, I wanted to get additional information. The description in their website does not fully answer my question – either I am missing some important component or the architecture is no different than the standard one.
They call the new architecture “DSP technology”. This label is a great choice on two counts: use of a well-known, but misapplied acronym (DSP does not refer to the more well known “Digital Signal Processor”, but “Directed SIP Peer-to-Peer”); use of two most attention grabbing phrases in VoIP (SIP and P2P). The following is their description of the technology: “When placing a call using Fusion’s Directed SIP Peer-to-Peer (DSP) technology, customers automatically access a central registry for authentication, enhancing security when compared to many peer-to-peer alternatives. A very sophisticated and powerful routing engine then facilitates a connection directly between calling parties without having to go through another user’s computer or calling device, as is required in other peer-to-peer models.” This really looks like standard SIP architecture. It doesn’t look like it is related to P2P SIP.
The next interesting item that caught my attention is their claim on another revolutionary idea – Internet Area Code (looks like they have even trademarked this term): “eNumber™, which is an Internet telephone number that begins with , the revolutionary worldwide Internet Area Code. efonica products and services require no change to our customers’ current calling habits – they simply dial 10 in front of a number they are familiar with. efonica members have the option to use their phone numbers as their eNumbers or we can assign them new, unique eNumbers. We employ an automated authentication process to ensure the numbers belong to the customers registering them.” I am not sure what is so revolutionary about it. It is not clear how this is different from ENUM. Doesn’t PhoneGnome use an automated and authenticated registration process? They do not give any clue as to why they require dialing the two additional digits. I hope it is not because they can trademark an often used phrase.Posted by aswath at June 18, 2006 10:48 AM
