Q. Describe the warranty for the Cisco UC300 Series.
A. The Cisco UC300 Series has 1 year of hardware support and 90 days of software support though the Cisco Small Business Support Center. It can be expanded with 3-year Small Business Support Service.

Buy the extended support within 90 days... that's what my sales person told me...
If you want to double check and talk with someone, I'd try Partner Helpline, but here are some other links as well:

Thanks,
