Why Cisco Phone Hardware Version Matters in Your Customer’s Migration to Webex Calling

Your customers might rely on you to guide them through every stage of their cloud migration journey. When moving from Cisco Unified Communications Manager (CUCM) to Webex Calling, there’s one technical detail that can impact success: Cisco phone hardware version.

‍

Why Knowing the Cisco Phone Hardware Version Matters for Migration

Webex Calling requires Cisco phones to run Multiplatform Phone (MPP) firmware, which is different from the Enterprise firmware used in CUCM. But not all phones are compatible with MPP, and compatibility can depend on the hardware version.

‍

For your customers, this might mean:

Incompatible hardware can’t be migrated to Webex Calling.
Upgrades or replacements may be required.
Delays or service gaps if this isn’t identified early.

‍

For you as a partner, it’s an opportunity to deliver added value through proactive planning.
