As a rule I tend not to blatently and overtly efuse praise for my clients and let others in the media and blogosphere do their talking for me. Call it professionalism, courtesy and respect for others and also to steer clear of hype.
One of the clients of our agency, and one that I not only use regularly, but believe in is TelEvolution and their breakout product, PhoneGnome. The reason I like it, is that PhoneGnome lets me do everything that VoIP and SIP are set up to do, without dislodging the PSTN world and all that it reliably still provides.
This past week founder David (Mr. Blog) Beckemeyer, who as an Internet veteran (he co-founded Earthlink), wrote a very passionate, polite and definiative post about the new world of telephony and pointed to a post by Aswath Rao. These are two smart dudes, far more technical than I could ever be when it comes to telephony.
David's very passionate post is a must read. Not only is it dead on the mark, but it builds a case for "network coexistance", not only neutrality, while also telling the world why PhoneGnome is there now with the idea of Network Coexistance.
