attend transfer phone B to phone C:   
1.  On the phone A presses FLASH to hear the dial tone.   
2.  Phone A dials the phone C’s number followed by # (or wait for 4 seconds).

Note: When attended transfer fails and A hangs up, the HT812/HT814 will ring back user A to remind A that 
B is still on the call. A can pick up the phone to resume conversation with B.
