Anyway when I carefully did the test I came to the conclusion that the Audio I was producing was terrible, seems I was lucky to do some improvement by switching off the AGC.

Further I have come to the conclusion that if I could 'force' GSM codec I had to be able to do ok as test we have carried out from a 'dial-up' connection , the audio was impressive. Tomorrow this will again be tested.

At the moment I have hit another problem with the sjphone, it will not respond to *600 echo check, well seems that WireShark sees lots of data but I don't hear anything, no ringing, no audio, just seems to run. My thinking is that if the echo test does not work then other problems will follow.

Any ideas?

What happens if you dial just 600?
