[cisco-voip] IP Phone Spam?

[STEVEN CASPER]

Anybody have any idea what this might be? This is from user who has witnesses to this event and has always been reliable when it comes to reporting troubles:
 
"Music began to emit from the speaker of the IP deskphone, followed by an advertisement for someone hawking software.  I had not received or placed a phone call.  When the voice got to the end of the advertisement, the sound disappeared and the phone functioned normally."
 
There were no line keys lit and the user was unable to control the phone to get rid of the audio. We have an Informacast system but the log files indicate no broadcasts to her telephone. Could it be some sort of EMI/RFI? The user has a 7961.
