Claim:
A processor-implemented method of operation for a unified messaging system (UMS), comprising: scanning a message for certain information, the message comprising a voice channel security level (VCSL) associated with the message and being stored for a user in the UMS; automatically setting a security attribute to the VCSL of the message based upon detection of the certain information, the certain information including one or more words, phrases, or addresses that satisfy predefined rules; receiving a request to listen to a message stored in the UMS, the request coming from the user connected to the UMS via a voice communication channel over a corporate network; negotiating with a telephone device of the user to secure the voice communication channel when the security attribute is set in the VCSL; playing the message to the user if the voice communication channel of the corporate network is secure; otherwise, prohibiting playout of the message over the voice communication channel; and notifying the user that the message cannot be played due to the lack of security in the event that the voice communication channel is unsecured; determining whether the recipient is within a transmission range limit of the corporate network; if the recipient is outside the transmission range limit, negotiating with a cellular network to provide a secure channel over which to play the message.
