Your scenario (multi-vendor conference call, urgency of resolution) implies a problem in a production environment.
When architectures are fully end-to-end tested before being put into production, problems like these are eliminated long before solutions like complete hardware replacement are palatable to the business people signing the checks.
In my experience, these are best practices and extend to things like configuration management and code upgrades for everything from access switches to firewalls, load balancers, etc.
