The embodiment of the invention relates to the field of data synchronization, and discloses a same-number multi-terminal call data synchronization method for a VoIP (Voice over Internet Protocol) system. In the invention, the existing SIP signaling channel between the terminals and the SIP server is multiplexed, and the control information is transmitted to negotiate to establish the end-to-end data channel which does not pass through the SIP server. And then, the terminal executes a set of four-stage handshake synchronization protocol based on an incremental change log through the end-to-end channel to synchronize call data. The problem that the related technology in the field depends on a synchronization server or is limited by near field communication is effectively solved, and real-time synchronization and consistent convergence of service data between terminals are realized on the premise of keeping the existing VoIP signaling architecture unchanged and not additionally deploying a special centralized data synchronization server; the system reliability is improved; and the deployment and maintenance cost is reduced.

A serverless Page Party (SPP) station is provided for page announcing and party line conferencing that is configured to implement mutual provisioning to allow all SPP stations within a system to mutually maintain their configurations in runtime, and multiple master station negotiation and master failover. Plural SPP stations are connected with Ethernet cable or WIFi to a network and therefore without need for expensive and cumbersome cabling and daisy-chain configuration among stations. SPP stations route packets between each other via multicast technology and without need for a IP-PBX or other server (e.g., a SIP server) for controlling inter-station connections. In Mutual Provisioning Mode, SPP stations operate using a system configuration obtained from other SPP stations already on the network using a command channel. System configuration is maintained by a SPP station designated as a master station. Plural SPP stations can negotiate among themselves to designate a new master station.

The application discloses a communication penetration method and system based on a session initiation protocol, and the method comprises the following steps: forcibly intercepting a data packet sent by a SIP terminal to a SIP server, converting a source IP of the data packet into a public network IP, converting a source port of the data packet into a target port, replacing a private IP and a port carried in a header connection field in SIP signaling of the data packet with the public network IP and the target port, and replacing a private media IP and a port in SDP information with a public network IP and a target media port when the SIP signaling carries the SDP information. Therefore, it can be seen that a boundary device uniformly intercepts and processes SIP data packets, fixes a port conversion relationship during registration, synchronously modifies a private address and a port in a signaling header into boundary device public network information, realizes consistency of network layer and application layer address conversion, and avoids SIP signaling address mismatch in a NAT environment.
