What are best-in-class benchmark for deployment times for XCaaS deployment?

Dear Members,

Any insights on XCaaS deployment time benchmarks will be helpful. Assuming an enterprise customer with >$5K MRR and multiple US sites:

1) What is the industry benchmark for how long it should take to get the first site live and getting value out of the purchase?

2) Does that benchmark change if deploying UCaaS vs. CCaaS?

3) Does that benchmark change if deploying hybrid - both UCaaS/CCaaS combined at one go live?

Thanks,

Divya
