Error path behaviour across Flow Designer activities
Verified 2026-09-15 · 22 sources · tier 2 · 2 disputed · 1 superseded
Also known as failure code, no-input timeout, undefined error.
Flow Designer activities present failure conditions through dedicated branches, generic undefined error nodes, and failure variables 2015. Only 6 activities carry error branches beyond the generic undefined error node: menu, collect digits, virtual agent, virtual agent version 2, queue to agent, and cryptographic hash 20.
Activity error branches and variables
The named branches on the menu and collect digits activities are a no-input timeout and an unmatched entry 17. For the virtual agent activity, the error code variable takes 4 values: no error, maximum no input, termination character without input, and system error 21. Most activities that describe failure carry the detail in a failure code and a failure description variable rather than in a branch 15.
Flow termination and activity documentation
Cisco warns that the End Flow activity should not be used in an interactive voice response flow, because doing so may result in dead air and the call may not disconnect 14. In the field, a table headed as GoTo activity error codes contains output variable descriptions rather than failure codes 16.
Documentation discrepancies
Sources disagree on the error path for the Parse activity: the Parse activity's own section describes an undefined error path, while the error handling section lists Parse among 4 activities that lack one 18. Sources disagree on publish rules as well, as the article gives 2 incompatible statements about whether a flow missing an error path can be published 19.

What remains uncertain
Sources disagree on whether a flow missing an error path can be published 19. How an interactive voice response flow should end when End Flow is unsafe there is not covered by the sources below. The values each activity's failure code variable can take are not covered by the sources below.
