Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 93

An engineer with ID0123456789 is designing a new dial plan for a customer that has offices in several countries on four continents around the world. This client also wants to integrate with a Microsoft Lync backend. Which dial plan type does the engineer recommend?

Answer options

• A. H.323
• B. SIP URI
• C. E.164
• D. TEHO

Correct answer: C

Explanation

The E.164 dial plan type is recommended because it provides a standardized format for international phone numbers, making it ideal for a client with a global presence. Other options like H.323 and SIP URI are more suited for specific protocols and may not address the international dialing requirements effectively. TEHO, or Toll-Bypass, is not applicable in this scenario as it focuses on cost-saving measures rather than a comprehensive dialing strategy.
