Absolutely! We expect every device we sell to be operational for at least 10 years. The 7941/61s were end-of-sale 10 years ago, and will still work with supported versions of CUCM for a few more years. In average that's about 2 decades of usage. Few technologies can claim this longevity. For the 7940s and 7960s, the timeline is even longer.

While we don't like to use this space to bash competitors, it is important to highlight that Skype for Business follows a different policy. Our understanding is that phones that work with it are not natively supported with Microsoft Teams, so customers will probably have to upgrade at much faster pace.

The long support for our phones is and will continue to be a Cisco differentiator.
