while in incoming call and outgoing call the following commands not working properly.Help me with that if there is any other BT commands for these ACTIONS

1.HOLD =BT command takes time to execute and when we send the Command at fast two times(i.e press and release) second time not Working properly

1.CALL 13 OUTGOING 2=is this the BT command to put into hold ? If these means it is not working properly.please say if there is any other command.

2.END=sometimes first time not works and second time it works.  
BT COMMAND “CALL 13 END” to terminate the call

1. PB\_PULL 16 1 2 PB\_PULL 16 1 3 PB\_PULL 16 1 4=commands to fetch the incoming call,outgoing call,missed calls  
PROBLEM=It is always not giving the correct data,it is giving in mixed order

4.sometimes BT COMMANDS works dependant on the phone and I tested with four phones.
