On a VXML gateway with Cisco CVP, which Cisco IOS application service specifies the number of significant digits that are expected to be prepended to the dialed number?

Question

Options

• Abootstrap.tcl
• Bringtone.tcl
• CBootstrap.vxml
• Dhandoff.tcl

• A
  85% (28)
• B
  9% (3)
• C
  3% (1)
• D
  3% (1)

Explanation

bootstrap.tcl is the Cisco IOS TCL application service deployed on the VXML gateway that handles initial call setup for CVP. Within its configuration, the sigdigits (significant digits) parameter controls how many digits, counted from the right of the dialed number, are considered meaningful and prepended when routing the call - this is essential for correct digit manipulation in CVP environments.

Why the distractors are wrong:

• B. ringtone.tcl - plays ringback/hold music to callers during transfers; it has no role in digit configuration.
• C. Bootstrap.vxml - a VXML document (not an IOS application service) used in older CVP architectures; digit-manipulation settings live in the TCL layer, not VXML markup.
• D. handoff.tcl - manages call handoff between CVP components (e.g., passing a call from the VXML gateway to an agent); it does not define significant digit behavior.

Memory tip: Think "Bootstrap = Beginning." bootstrap.tcl is the first script the gateway runs when a call arrives, so it logically owns the foundational digit-signaling configuration before anything else touches the call.
