Looking For A Wideband Capable Soft Phone

Over the coming weeks and months I hope to explore wideband voice in greater depth. My recent purchase of a couple of Polycom IP650s and the Siemens S685IP provide me with some hardware end-points. I may also buy a snom phone as well, with the optional Klarvoice handset.

However, some of what I wish to undertake would be well served by a soft phone. As yet I have been unable to find a software that supports the G.722 wideband codec.

Counterpath‘s Eyebeam & Bria claim to support G.722 but in fact they only provide that feature to OEMs licensing a significant quantity of copies. They don’t provide it in retail versions sold from their web site. It grieves me to think that I bought a number of X-Pro licenses then had no migration path into the newer products as they were introduced.

Snom offered a soft phone implementation of one of their 360 hard phone, but it doesn’t support the full suite of codecs found in the hardware implementation.

This afternoon I learned about eyeP Media Communicator 6.0 and downloaded a copy for evaluation. It claims support for G.722 and G.722.2, which would provide not only wideband audio but also lower bandwidth usage. I’ll post about this once I’ve had a chance to give it a workout.

I’ve looked into various softwares including Gizmo5, Firefly, Wengo and Zoiper. WengoPhone supports AMR-WB  which is G.722.2, but not the older G.722. Since my hardware phones support G.722 I need the soft phone to handle this as well.

So I’m still looking for options. I’ve posted questions about wideband capable soft phones on the asterisk-users and voip-users-conference mailing lists but there were almost no responses.

Any suggestions are most welcome.
