The other problem with the touchscreens and VoIP is that the telephone audio circuitry was not accessible by software running on the phone. Here is a block diagram: http://www.blurbco.com/~gork/tuxscreen/shanblock.gif A modification (ShanIP2) was designed to make the handset/speakerphone audio to/from the dsp accessible via the UCB1200 audio chip, and I had designed a PCB for the circuit here: http://www.blurbco.com/~gork/tuxscreen/shanip2-gork8.gif > So have a look there : > > http://www.lart.tudelft.nl/ > > You will find there the hardware that evolved from what was in the > Tuxscreen.

The LART was actually around before the tuxscreen, and although it is similar, you'll find that most SA1XXX based designs are. It is still a good little board and fun to work with, as is the Tuxscreen if you can still pick one up used from someone. Anyway, since this is starting now getting pretty offtopic, I should probably leave it at this...

The kits would be over $300US and don't have a case or software loaded on, nor a phone interface.

I must say that I would be EXTREMELY interested in distributing such phones here in Switzerland ... We see a lot of demand here ... I am even willing to beta-test if needed.

I've talked recently to the head of R&D dept. of Telkom Telos (www.telos.com.pl) - a big Polish company specialised in making phones. I gave them the idea of creating a cheap (cost-effective) hardware IP phone. The phone we discussed would include hardware support for IAX (though probably SIP/sth. else would be required too if it were to hit the market.. what do you think?) and GSM 06.10. Although they have no previous experience in IP phones, they were quite interested and promised to have a deeper look into the issue. So now for the big part: everybody PLEASE give your suggestions about what the IP phone of your choice should look/work/... like. The main reason we started the talks was the cost of currently available phones (even $70+s&h is a truckload of money for a phone here in Poland) but any and all suggestions are welcome. I'd also love to hear from the more hardware-oriented people - do you have any suggestions about used chips, controllers, codecs, whatever? As I said, although they've been making phones for years, they haven't built an IP phone before so they have to research the possible elements used. Why not make it easier for them? :) With Telos being a specialised factory, there's the benefit that e.g. good-looking cases are no problem at all, and if low price wasn't the goal, touchscreens and all would be an option too - maybe some "deluxe" edition? An alternative design that came up was a bigger (say, 12/24 ports) gateway with some embedded Linux running on an industrial PC (as beefy as circumstances require - any comments?) with plain RJ11 sockets on one side and Ethernet on the other.

Re: [Asterisk-Users] Hardware IAX phone (please read and reply!)
Sounds like a good idea.. My suggestion on looks and features would be to look at somthing like the Snom200, features like the ability to connect a standard pc type head set to the phone a great cost cutting features.. As for codecs I would look and G.711, G.729, GSM, iLBC and Speex.. That way you have covered both high and low bandwidth, closed source and open source codecs.. Look ate STUN support and possibly uPNP.. As for the rest just stick to the standards for SIP ( and IAX if you decied to impliment it).. If the price per phone can be brought down closer to the cost of a standard analog phone then there will be no reason why VoIP will not take over the telecomunications of the world.. So I would say in the fisrt instance get a low cost, hight quality, reliable product created first and if there is a need then look at the "Delux" products.. Unfortunately the VoIP world is full of "Delux" but not enough budget products.. It seams that most only think of the global enterprise and not about the worlds SME's..

Re: [Asterisk-Users] Hardware IAX phone (please read and reply!)
If there was a native IAX phone with GSM support and was around $70, I'd buy a few, and I know several people in my social groups would get them. I could even make a business case to get them for the office.
