For the past few weeks I’ve been hunting for a soft phone with specific wideband voice capabilities. I’ve found a couple but there arises complications.
Wideband-capable hard phones usually support G.722, G.722.1 or G.722.2 (aka AMR-WB) codecs. There are other codecs out there that support wideband voice coding. Speex is the one most often cited. However, Speex support in hardware is extremely limited. So Speex implemented in a soft phone is not going to help me evaluate interoperability with hard phones.
In September 2007 the folks at FWD put up a wiki in the hope of getting users to document how to configure various hardware & software SIP clients for use with the service.
At the time I was provisioning a handful of Polycom SoundPoint IP430 phones for use within Pixel Power Inc. I took the opportunity to document the configuration with FWD based upon the use of v2.1.2 firmware.
Although my example was on the IP430 model it should be generally applicable to the entire SoundPoint line.
The word has come down that Hitachi has stopped making its Wifi SIP handsets and is exiting that line of business. If you liked any of their phones you may still be able to get them from retailers existing inventory, but numbers are expected to be limited.
One reader indicates that they think the process of changing the active VOIP account on a snom m3 is troublesome. Here’s a short video I did some time ago documenting the keystroke sequence using my snom m3.
The phone supports up to 8 separate registations. This means that it can take incomming calls from eight separate sources. However, when making outgoing calls it only uses one of the accounts. You can set which one that is by default for each handset.
In my experience this is not a problem, as I make all outgoing calls through one account anyway. But by allowing multiple registrations I can take calls from auxillary services like Free World Dialup, IPKALL, IdeaSIP, etc.

I have worked from a home office for over ten years. Just over two years ago, I transitioned both my home and office to a completely VoIP-based phone system. My goal was to improve my ability to stay connected while reducing my monthly operating costs. I carefully selected high quality, business-class SIP desk phones with a variety of features to make running a small office easier.
