摘要
A method for transmitting content in a call established via media gateway control protocol includes: encrypting an RFC, Request for Comment, 2833 message with a first key; and sending out the encrypted RFC2833 message. The key used for encryption and decryption may be configured in advance on a calling and a called media gateways, or be sent from a soft switch device once and for all, or be sent from the soft switch device every time when a call is initiated. The key sent from the soft switch device may be in clear text or be encrypted. The technical scheme of the present invention greatly improves the security of the content in the RFC2833 protocol transmission.
