beginning of the dialed string before the call is placed via the selected
trunk.
Example:
The users will dial 9 as the first digit of a long distance calls. However, 9

digit should be stripped before the call is placed.
Specify the digits to be prepended before the call is placed via the trunk.
Those digits will be prepended after the dialing number is stripped.
Failover trunks can be used to make sure that a call goes through an
alternate route, when the primary trunk is busy or down. If "Use Failover
Trunk" is enabled and "Failover trunk" is defined, the calls that cannot be
placed via the regular trunk may have a secondary trunk to go through.
Example:
The user's primary trunk is a VoIP trunk and the user would like to use the
PSTN when the VoIP trunk is not available. The PSTN trunk can be
configured as the failover trunk of the VoIP trunk.
