Elie,
Unfortunately, if you are trying to use the fake ring tone (progtone = Yes), then this will interfere with the answer supervision and it will not work correctly. Additionally, this will cause further problems as the A800 will not allow a busy signal to pass through, so if the number dialed is busy, the caller may never know this as they will only hear ringing. I would suggest that you set progtone to No on the A800 and if there is a way for the cisco to send a ‘#’ at the end of the dial string, the Tenor can dial this out to the PSTN and this may speed up the PDD.
