Hardware phones that do 48Khz Celt: Was Re: Is there any license G729?
Are there any hardware phones that support 48 Khz Celt and automated/mass deployment? Craig. 2009/6/30 Jason White <jason@jasonjgw.net>:

48khz Celt (celt@48000 in your codec preferences) sounds wonderful with FreeSWITCH. To test, run two FreeSWITCH instances, both with mod_portaudio. This also works well in 48khz conferences.
I wouldn't use G.729 even if it weren't encumbered by patents - it's G.711, G.722, G.722.1 and (my current favourite) Celt all the way.

Actually... FreeSWITCH in a phone could be a very good project. The main obstacles are: 1. Someone would need to design and build the hardware, or find existing hardware that would be suitable. 2. A script would have to be written to control i/o so that the keyboard and display of the phone could be used to make calls.
Now who can we con into building an open platform thats nothing more than a linux box shaped like a nice looking phone? :P Video and Touch Screen are a requirement :) /b On Jun 29, 2009, at 8:41 PM, Jason White wrote:

Well Snom phones use linux. I wonder if the the Chinese factory that pumps them out does grey market versions. Unfortunately that doesn't meed the video, touch screen or even the nice looking requirements. Craig. p.s. Above thoughts are my own not my employers. 2009/6/30 Brian West <brian@freeswitch.org>:

Well the 8XX series is much prettier than the 3XX series. Though I wonder if anyone has thought of porting FreeSWITCH to the Palm Pre? Craig. 2009/6/30 Hadley Rich <hads@nice.net.nz>:

Palm Pre is Linux-based, so shouldn't be that difficult so long as you can get a working portaudio up and running (it looks like pulseaudio has already been ported, so I presume ALSA is ready and waiting in the kernel - FS might just build out of the box!). -- Regards, Jay Fenton, CTO <jay.fenton@howlertech.com> Howler Technologies Ltd, 11 Charlotte Mews, London, W1T 4EQ tel: +44 207 099 7095 fax: +44 207 099 7098 http://www.howlertech.com/ http://www.linkedin.com/in/jfenton Registered in England & Wales, Company No. 06285634

Craig. Most of the pure VoIP chipsets aren't capable of running at 48k samples/second, so off the shelf phone hardware platforms probably won't cut it. The phones with video capabilities might have 48k sample/second facilities. 2009/6/30 Jason White<jason@jasonjgw.net>:

Even if you did have a phone that could do it, you would have to design a completely different handset with high end audio components to hear any difference. Having said that, I can see an application for a hardware "phone" that has balanced line in and out connections, so you could use it for broadcast applications. This could replace all the hybrids you normally have in an audio control room, and allow for full-quality phone links if both sides support it. curriegrad2004 wrote:

You would certainly need a better mic and earpiece, but they don't need to be very expensive parts to get pretty good results, and making them fit the existing mouldings is unlikely to be that hard. The killer would be if the plastic moulding has a mass of resonances. You might need to re-engineer the entire thing in that case.

There are video conferencing platforms which are already like that.
