Cisco confirmed it is possible to eavesdrop on remote conversations using Cisco voIP phones.

Cisco adds that Extension Mobility authentication credentials are not tied to individual IP phones and that "any Extension Mobility account configured on an IP phone's Cisco Unified Communications Manager/CallManager (CUCM) server can be used to perform an eavesdropping attack."

The readers that notified us indicating that the phones had been updated per recommendations of the vendors. One of our readers indicated the Cisco TAC is unreachable due to volume so my guess is that Shawn and Peter aren't the only ones that have noticed the problem."
