Has anyone used the Audiocodes MP204? It appears to be close to the
Grandstream 4004 (probably off the same assembly line), but isn't
Audiocodes a slightly 'better' company?

I really want to know Chuck...is there anything you have not built?
You were on the Apollo team when you were 12 right?

I once built an amplified headset for a large call center

attached modem to send the C and D tones to connect and disconnect

discovered the modems that would be on the line could not generate
C & D tones.... arrgh...

I don't think anyone even uses the touchtone "D" button, do you
see it on your phone?

Is it possible that what you are hearing is a beep when another
person is calling that line (Call waiting ?)
Also, If you don't mind me asking..
Why are you doing pots to sip conversion ? why not just a
straight sip trunk ? (i.e. sip origination )
