No, if they are operating correctly DECT and WiFi shouldn't interfere with each other.

DECT operates in the 1900Mhz frequency range, specifically 1880-1930Mhz (in some regions up to 1980Mhz). Your Yealink W-series Wireless phones fall in this category.

Most WiFi operates in the 2.4Ghz (802.11b/g/n) or 5GHz (802.11a/h/j/n/ac/ax) frequency ranges. Your AP's fall in this category.

There are also some limited use cases for WiFi in following frequency ranges: 3.65Mhz (802.11y), 4.9 GHz (802.11j), 5.9 GHz (802.11p), 60 GHz (802.11ad/ay), and 900 MHz (802.11ah), but to my knowledge your Ubiquity UAP Pro AP's do not support any of these rarely used frequencies.

Since the operating frequency of these devices are significantly separated, they should not interfere with each other, assuming they are functioning properly.
