Errormessage on my Cisco 7925 wireless phone (network is busy)

Hello,

when someone calls me on one of my 2 Cisco 7925 wireless phones, they show message "network busy"  I have another Cisco 7921 (same phone number but newer) which seems to be ok with completely same settings. What could be the problem?

thanks

Check the data rates.

ok, thanks for the hint.  It seems that the phone is only working fine with 802.11a  mode.
