Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 25

Which two options are dial-plan challenges in a multisite Cisco Unified Communications Manager deployment? (Choose two.)

Answer options

• A. use of MGCP gateways instead of SIP trunks
• B. use of same DID numbers in multiple sites
• C. use of same length directory numbers all over the network
• D. use of +E.164 directory numbers and extensions for phones and services
• E. telephony service provider requirements on number format and types AD

Correct answer:

Explanation

The correct answers are B and E. Using the same DID numbers in multiple sites can lead to conflicts in call routing and identification. Additionally, telephony service provider requirements often dictate specific number formats, which can complicate dial plans in a multisite deployment. The other options, while relevant to telephony systems, do not directly represent challenges specific to dial-planning in a multisite context.
