Note:
If the MICON T20/30 is connected with PBX as an extension, you will need to use a
special dialing format as following:
where the first "x" is the code to access an outside line, "P" is a special symbol
representing a pause of 2 seconds, and "1234567890" represents the area code and
forwarding telephone number (Fig.11).
