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 don’t see the monitor digits member or any means of changing things? I’ve spent over a week on this problem and six hours solid since your email and still can’t 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?

I’ll keep trying but I think I’m going to need more help.

After some discussion with Exceletel’s Fred Decker and some more testing, we’ve finally managed to identify what’s 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 can’t 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 haven’t already done so.

Your thoughts would be most welcome.

PS I’m expecting another HiPhone delivery tomorrow and will see if there’s any difference between the performance.
