Business can get their entire operation networked and making calls within minutes. Even large corporations can experience complete setup times (including phone provisioning, voicemail configuration, and ring group creation) in less than a day.
If you’re going to start with a common statement such as ‘Your call is important to us’ and the other statements you have heard, your prospects are going to walk away.

You can no longer have a lousy phone system that lacks compelling features. Modern phone systems offer redundancy to direct calls to cell phones in the unlikely event of an internet connection outage. Whether you’re selling the best office phone for a small business or international enterprise, a modern VoIP solution is within reach.
For at least the next two years, these trends are likely to become important selling points in most VoIP vendor-customer pitches. While that's great, be sure to fully understand what's being offered and how the vendor is going to go about delivering it. Is a 5G implementation truly standards-based or are there still some proprietary hardware or software components? Have much will any new security measures affect overall voice performance, and does the vendor fully support the changing security requirements in important industry regulations, like HIPAA and SOX?
