A few weeks ago I wrote a piece on ENUM, what it is, and why it is important to the continued development of VoIP.
Today the folks over at NerdVittles have an informative piece on how Asterisk users can leverage ENUM for toll-bypass, by way of Gizmo5’s (previously SIPPhone.com) ENUM peering agreements with a wide range of carriers, including:
Access One, Airadigm, Allegiance, Alltel, Cablevision Lightpath, Cat Communications, Cbeyond, Cellcom, Cellular Properties, Centennial Wireless, Choice One, Cincinnati Bell Wireless, Cinergy Communications, Cingular, CityNet, Cleveland Unlimited, Comcast Digital Voice, Commpartners, Conversent Communications, Cox Communications, CP Telecom, CTC Communications, Dobson Cell, Eureka, Globalcom, Heartland Communications, Illinois Valley, ITC Deltacom, LDMI, McLeod, Metro PCS, Mpower, Nationsline, Nextel, Nextera Communications, Paetec, RCN, Sprint PCS, Talk America, Telnet Worldwide, T-Mobile, US Cellular, Verizon Wireless, and XO.
Ward even includes some sample code on setting up a FreePBX trunk for Gizmo5. NerdVittles is a must read for anyone out there looking to keep their finger on the pulse of the Asterisk community.
