Contact ID Mode Call Handling Functionality (listen in mode)

The Caresse unit will raise alarm calls in the following manner:-
1. The Initial Alarm Call
Caresse unit makes an alarm call and signals a new event code '1'.
The monitoring station (e.g. Osborne-Hoffman receiver) can either:
A: suspend the unit by sending a '#' followed by '3'.
B: clear the call by sending a '#' followed by '6' or '*' followed by '#'.
If neither command A or B are sent then the unit will generate a time out warning after 5
minutes. The timeout warning can be cancelled and the timer reset by sending any
DTMF tone during the warning period. If the warning is not cancelled then the unit will
disconnect and enter suspend mode.
2. The '20 minute' suspend mode
The initial call is cleared and the unit goes back on-hook, but stays in a suspended call
mode.
If an incoming call occurs in this period then the unit will auto-answer after 1 ring in
handsfree mode. The incoming call is cleared either by the resident clearing the call
using cancel or by monitoring station using '*' then '#'.
The call can be suspended again by the monitoring station by sending '#' then '3'.
If the emergency help arrives then they will press the blue button. This will generate a
reset call to the monitoring station in Handsfree mode (Event code '3' as per the Contact
ID spec.). The unit will require the operator to clear the call down using '*' then '#'
otherwise it will time out after 5 minutes and clear down. The 'help arrived' reset call will
be made to the same telephone number as the original call. Up to 3 attempts will be
made on the reset call in case the monitoring station is busy.
3. The '20 minute' suspend period has elapsed
If the monitoring station didn't call back and clear the call and no emergency help arrived
to press the blue button then a new alarm call will be generated (Event code '6' as per
Contact ID spec.). The unit will make up to 7 re-attempts in this way.
