*70: Deactivates call waiting on one outgoing call

This will Disable Call Waiting on a single outbound call.

To use:

Pick up the Phone Power phone.

Once you hear the dial tone, dial *70 + phone number you are calling + #. Example: *70 818 555 1212 #.

The first call that is received while you are on an active phone call will not send the call waiting signal and will instead be directed as if the Phone Power phone was Busy.

Any call placed after that first Busy call to the Phone Power phone will function normally.
