It has finally happened and I couldn't be happier. When I first got my iPhone I couldn't wait for the time when I could make extension to extension VOIP calls via my iPhone. The iPhone has wifi access. All it needed was someone to put some SIP software on the phone and, combined with Junction Networks OnSIP hosted PBX, it would be ready to go.
That time has come. Over the weekend I downloaded fring and after just a little tweaking I got it to work. The device registered to Junction Networks and my first call was to extension 7008: Tim in Chicago. All I had to do was bring up the 'dialer' in fring and dial 7008 and hit the 'SIP' button and it dialed Tim's extension. Tim only saw a call from me, ext. 7001. As far as he knew I was at my desk. In reality I was 30 feet away on my iPhone speaking to him over the iPhone's wifi connection. Next, I told Tim to hang up and call me right back. He dialed extension 7001 and fring notified me on my iPhone that I had an inbound call.
The calls sounded great. There was no echo and no delay. No question the call was better than a normal cell-phone phone call. I shared my story with fring and received the following response from fring co-founder and Chief Technology Architect Boaz Zilberman “fring prides itself on being a best-of-breed mobile Internet communications and community application, offering its users the ability to talk, chat and interact with fellow fringsters and all their online buddies using their mobile Internet connection. Partnerships with forward-thinking companies such as Junction Networks offer a new level of openness and connectivity and provide a glimpse of the future in which mobile Internet and traditional telecoms converge to provide as rich and flexible a user experience as possible.”
The best part is that extension to extension calls are FREE. Junction Networks never charges for extension to extension calls, and since fring calls use the wifi network and not the cellular network, it does not take up cellular minutes.
The fring dial pad interface does not have buttons for actions like 'Hold', 'Transfer' and 'Conference' so those features do not work in the fring interface. DTMF (touch tone) is disabled during a call. It would also be useful to be able to put SIP addresses into contacts and dial a contact's SIP address as opposed to being limited to dialing only numbers. Even with those restrictions, fring is a great start.
AT&T just announced that they are offering free wifi to all iPhone subscribers at any AT&T wifi hotspot. This includes Starbucks. Customers can locate Wi-Fi spots through AT&T's online tool or can locate a Starbucks using this tool.
With Junction Networks, since we allow our users to be registered on up to 10 different devices, this is a free addition to our service offering. There are no additional charges to add a device to the system. (Nor do we charge per user, so you could add a new user and setup the fring device as a user separate from your normal user as well.) All of our users can now setup their iPhone (or other mobile device) to act as their extension on their company PBX. No more 'forwarding calls to your cell phone'. Now, your cell phone IS your extension!
