Abstract

This invention relates to a telephone encryption method, device, and medium based on an IPPBX system. The method includes: when encryption is required on the calling channel, adding a number encryption identifier to the calling channel before initiating the call; when encryption is required on the called channel, adding a called encryption identifier to the calling channel before initiating the call; when an incoming call is received, determining whether the calling channel contains a called encryption identifier, and if so, adding a number encryption identifier to the corresponding called channel; when a SIP packet needs to be sent to the calling channel, determining whether the calling channel contains a number encryption identifier, and if so, encrypting the number in the SIP packet; when a SIP packet needs to be sent to the called channel, determining whether the called channel contains a number encryption identifier, and if so, encrypting the number in the SIP packet. This invention provides strong privacy protection, ensuring that sensitive information such as phone numbers is not leaked.
