Is there any way to check what power level a 7921 is using at a given moment?
Yes, either locally in the UI (Settings > Device Information > WLAN) or via the phone webpage under Information > Wireless LAN.
The 7921G phone will use what's advertised by DTPC by default. Otherwise it will use the highest tx power available based on the regulatory domain or 802.11d info provided by the AP.
See the 7921G Deployment Guide for more info @ http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7921g/6_0/english/deployment/guide/7921dply.pdf.
