Question

A Webex Calling administrator has configured a multi-location deployment. Users report that when they dial a 4-digit extension that also happens to match the beginning of an enterprise significant number (ESN) pattern used for inter-site abbreviated dialing, calls are being routed to the wrong destination. The administrator wants to understand how Webex Calling decides which match to use when both an internal extension and a dial plan pattern could apply to the dialed digits. In the Webex Calling call routing process, which behavior determines the outcome?

Accepted Answer

Webex Calling first attempts to match the digits against internal numbers (extensions and users within the org/location) before applying dial plans and route choices for external routing.

Answer

Webex Calling always evaluates configured dial plan patterns first, so ESN patterns take precedence over internal extensions regardless of length.

Answer

Webex Calling routes based solely on the longest numeric string, so the ESN pattern always wins because it contains more digits.

Answer

Webex Calling sends any ambiguous dial string to the PSTN gateway to let the carrier resolve the correct destination.
