How-To Series: Making Use of Wideband Voice Right Now!

polycom_ip650_256Not long ago telecom writer and blogger Doug Mohney issued forth a Tweet asking:

“Anyone out there using HD calling (G.722) on a daily basis?”

I’ve not met Doug, although I sat a few seats down from him much of the day at last month’s HD Communications Summit. I’ve read his work at various places including FierceVoIP. Doug truly knows telecom.

What his tweet brought to mind is the simple fact that many people might be interested in making use of wideband voice, but not know where to start. I use wideband voice,  in one form or another, literally every day. If you’re a technical sort it’s not that difficult. For the non-technical it can be a minefield. So I thought I should offer some suggestions based upon my own SOHO experience.

As I set about writing this I discovered that it was going to turn into a fairly massive amount of information. There are many avenues to consider, some very simple and some more involved. It was well beyond one blog post so I’m going to present it as a series, with one post a week for as long as I have suitable material.

The first few posts are already in que. Look for the initial shot across the bow of HMS Legacy Telecom on Monday morning when I’ll be considering a really easy way to get started in wideband VoIP for little or no cost.

    Gizmo5 was purchased by Google — no signups currently allowed.
    Sipgate requires a SMS capable US cell phone for signup.
    OnSIP no longer has an a la carte free option on website.
    Skype is proprietary but works.

    Things seem to change quickly.

    • Indeed, there’s a lot of transitions underway. It’s been six months since this series was written.

      I believe that OnSIP still allows the a la carte option, but their new web site night not make it so obvious.
      Google will eventually open up Google Voice to SIP interaction and effectively replace Gizmo5.
      Not sure about the SIPGate policy. I don’t recall anything about that when I signed up my account.

    G.722 works with callwithus — at least between subaccounts which was my purpose.

    I’ve heard this may also be the case with voip.ms but they also seem to charge for calls between these subaccounts at $.001/min.

    • That’s possibly interesting. How exactly does it work? Do you dial by SIP URI or just by phone number where both numbers are using “callwithus” for example?
