Question

In an organization's US system, all users and phones have the full E.164 number as their only extensions. A business requirement mandates that an easily dialable number like 111 must be associated to the E.164 DID of the security helpdesk. Which method effectively achieves this requirement?

Options

  • ACreate a transaction pattern for number 111 and associate it to the E.164 extension of the
  • BCreate an intercom translation pattern for 111 and configure E.164 extension of the security
  • CCreate an abbreviated dialing speed dial for all the phones for 111.
  • DCreate a route pattern for number 111.

Why each option

A route pattern in CUCM is the correct mechanism to create a system-wide, easily dialable short number that maps to a full E.164 destination such as a security helpdesk DID.

ACreate a transaction pattern for number 111 and associate it to the E.164 extension of the

Transaction pattern is not a standard CUCM configuration object; it does not exist as a named feature for mapping short codes to E.164 numbers.

BCreate an intercom translation pattern for 111 and configure E.164 extension of the security

Intercom translation patterns in CUCM are used for one-way audio push between intercom-enabled devices, not for creating system-wide abbreviated dialing aliases for E.164 destinations.

CCreate an abbreviated dialing speed dial for all the phones for 111.

Abbreviated dialing speed dials are configured per phone and require touching every device individually; they do not provide a system-wide solution where any user can dial 111 without per-phone configuration.

DCreate a route pattern for number 111.Correct

Creating a route pattern for 111 allows it to be configured with a destination of the security helpdesk's full E.164 number, making 111 dialable from any phone in the system. Route patterns are specifically designed to define dialable digit strings and map them to gateways, route lists, or other destinations system-wide.
