Preliminary
 Rejecting Calls from Callers not in TLC's Phone Book
TLC will screen calls from unrecognized phone numbers (those not in the phone
book or new call list). If a call comes in on your mobile phone, screening will
consume one minute of mobile air time even if TLC terminates the call. To avoid
mobile airtime usage, you can set TLC to reject calls from any unrecognized
phone number and send the calls to the mobile phone's voice mail.
 Rejecting Audio when TLC did not Originate the Call
If you're talking on your mobile phone when you return home, TLC will
automatically reconnect your mobile phone to the TLC system, at the same time
retaining the call physically on your mobile phone. The reconnection may cause
a brief interruption in the audio. To avoid this interruption, you can set up TLC to
reject the audio transfer request.
 Use Network Operator Defaults for Call Waiting, Merging,
and Switching Between Calls
Call waiting and 3-way calling work differently for different mobile phone
providers (network operators like Verizon, AT&T, T-Mobile, and Sprint). Some
providers allow you merge (or conference) a waiting call with the active call, while
others only let you switch between the waiting call and the active call. Some
providers allow you switch between a third called party and the on hold
party(ies), and some only allow you merge (or conference) the calls. Some
providers allow you to use *70 to disable call waiting for a given call and some do
not.
TLC attempts to get the name of the network operator from your mobile phone. If
the phone provides the name and TLC recognizes it, it will use that network
operator's default settings. Otherwise, you will have to set them manually if you
want TLC to use the call waiting and 3-way calling features properly. The
following three options will be set automatically if you enable this option and TLC
is successful in getting a recognized network operator name.
 Allow *70 to Disable Call Waiting on Network
Some mobile phone providers allow you to dial *70 to disable call waiting on a
call-by-call basis; other providers will give an error message. TLC will
automatically add *70 to any number you dial if you set the Disable Call Waiting
option (see menu item Set up the Outside Lines). If you don't allow *70 and you
have call waiting disabled, TLC will instruct your mobile phone to ignore waiting
calls. You will hear waiting calls come in, but they will be immediately sent to
your mobile phone's voice mail.
 Call Waiting Merging
When you answer a waiting call, some mobile phone providers allow you to
merge (or conference) the waiting call with the active call, while some only let
