Jajah, in its effort to become a backend platform for VoIP services, has started offering call termination, billing and other such services to one and all comers. They got a big boost when they signed up Yahoo! Now, the Sequoia Capital-backed company has signed up SIPphone, the company behind Gizmo and will handle their call termination. Does this mean Gizmo’s call quality will increase? I certainly hope so - I have stopped using the service because of poor quality of voice.

Instead, I have opted for RingCentral, which recently introduced a Mac OS X soft client (in addition to a PC version) and it is doing a might fine job for me. I was highly skeptical of RingCentral in the past but they have won me over with their high quality service. (Full review, pending!)

Soft phones - whether they are from RingCentral, Vonage, Gizmo or Skype extremely useful. I almost never am close to a landline, but an internet connection is always handy. Using soft phone, I can make quick calls without really breaking away from the computer screen. I am not alone in professing a liking for Softphones. A Frost & Sullivan report says that as a percentage of total IP-telephone market soft phones share will increase from 5 percent to 20 percent by 2014. Softphone sales rose to 416,000 units, worth $18.9 million in 2007, up 30% over 2006.
