If prefix 7 is configured on the U1960 by referring to the following figure, which of the following statements are CORRECT? (Multiple Choice)

Question

Exhibit

Options

• AThis prefix can be used only by intra-office users. Another prefix needs to be configured to allow
• BExternal users can dial prefix 7 to call intra-office extension 7000.
• CIntra-office users can dial prefix 7 to call intra-office extension 7000.
• DIntra-office users can dial prefix 7 to call 77000. The U1900 will automatically delete the last digit.

• A
  29% (12)
• B
  71% (29)

Explanation

On Huawei U1900-series systems (including the U1960), a configured prefix is accessible to both intra-office (internal) and external users by default - it is not restricted to one group unless explicitly limited. This makes B and C correct: external callers can dial prefix 7 to reach extension 7000, and internal users can do the same. D is correct because the U1960 supports automatic digit manipulation - if an internal user dials 77000, the system recognizes the leading 7 as the prefix, strips it, and routes the call to extension 7000; this is standard overlap-digit deletion behavior in PBX prefix routing.

Option A is wrong because it falsely claims the prefix is exclusive to intra-office users and that a separate prefix is required for external access - a single configured prefix serves both user types simultaneously.

Memory tip: Think of a U1960 prefix as a universal shortcut key - once configured, it opens the door for everyone (internal and external), and the system is smart enough to silently erase the redundant leading digit before connecting the call.
