When dialing a number on an Avaya IP Office telephone, which dialed number has the highest priority?

Question

Options

• AUser Extension Number
• BOutgoing Line Group ID
• CRoute ID
• DSystem Short Code

• A
  5% (3)
• B
  2% (1)
• C
  92% (56)
• D
  2% (1)

Explanation

Route ID holds the highest priority because when a dialed string matches a Route ID in Avaya IP Office, the system immediately directs the call through that specific ARS (Automatic Route Selection) path, bypassing all other dial plan processing - it represents the most explicit, direct routing instruction available in the system.

Why the distractors are wrong:

• User Extension Number (A) is an internal directory identifier for reaching a specific endpoint, not a routing priority mechanism.
• Outgoing Line Group ID (B) identifies a bundle of external trunks but sits lower in the resolution hierarchy; the system still processes Route IDs before resolving line groups.
• System Short Code (D) provides dial plan rules system-wide, but short code matching is evaluated after Route IDs have been checked, placing it lower in priority.

Memory tip: Think of Route ID as the "express lane" - it skips all other traffic (extensions, short codes, line groups) because you've explicitly named the exact road to take. The more specific and direct the instruction, the higher the priority in Avaya's dial plan hierarchy.
