Just a final update on this issue.
The problem seemed to have been due the ADSL filters causing a drop in the level of the tones together with a slight roll off in the higher frequencies. This was overcome by Doron and the Way2call engineers so my thanks go out to all concerned.
Everything's now working perfectly!

After some discussion with Exceletelâ?Ts Fred Decker and some more testing, weâ?Tve finally managed to identify whatâ?Ts actually causing the problems. All we have to do now is to work out how to resolve it! Broadband filters for ADSL Internet which are common in most homes in the UK, seem to be affecting the tone in such a way as to prevent them from being detected. Removal of the filters 100% cures the problem but we canâ?Tt expect the public to remove them so we need to find a solution either in firmware or possibly an external compensating filter? We could try to sample the audio with and without the filter so that you could look into this if you havenâ?Tt already done so. Your thoughts would be most welcome. PS Iâ?Tm expecting another HiPhone delivery tomorrow and will see if thereâ?Ts any difference between the performance. Bill |

Doronsh Thanks for checking out my log files. I think I understand what you're saying but I still don't understand how to correct the problem. I look in linedevcaps and donâ?Tt see the monitor digits member or any means of changing things? Iâ?Tve spent over a week on this problem and six hours solid since your email and still canâ?Tt see the solution. The strange thing is that system works perfectly on all mobiles but 2 of our 6 land line test callers repeatedly fail to respond. There must be something different with either their landline or handsets to cause this problem but we all use similar modern phones that don't use any pulse dialling? Iâ?Tll keep trying but I think Iâ?Tm going to need more help. Bill |

I've just tested the detection threshold to determain which way round this number works but changing values between 20 to 20000 seems to have no effect. I would have thought that one of these settings would have made the system so insensitive that DTMF tones would be ignored.

I've done the download and reflashed the unit. It may have made a slight difference because I can now dial in from my home which I couldn't do before the reflash. But still several people still report the keys don't respond.
I get the feeling that the detection level is just on the limit. The tone detection threshold is currently set to 9999 which I assume is maximum sensitivity? Other than that, I have the echo suppression turned on but I'm not sure if that makes any difference.

I seem to be having some issues with reliably detecting key presses made by the calling parties. Most of the time it works fine but quite often someone rings and the tones either don't get detected at all or it's a bit hit and miss.
I seem to recall reading somewhere that the DTMF decoder can be optimised for either the handset or the line but not both. Any thoughts on this would be gratefully appreciated.
Bill
