This application discloses a method and apparatus for transmitting VoIP media parameters. The method is applied to an initiating end, wherein the initiating end is one of an IAD and a SIP Server, and the corresponding receiving end is the other of the IAD and SIP Server. The method includes: after a normal VoIP call has been established between the IAD and the SIP Server, if it is detected that at least one of the packet duration and encoding / decoding rules in the current VoIP media parameters needs to be updated, a notification message is sent to the receiving end, wherein the notification message includes the value to be updated for the parameter currently to be updated; obtaining a response message from the receiving end to the notification message, wherein the response message carries a judgment result on whether the value to be updated for the parameter currently to be updated is supported; determining whether the parameter currently to be updated has been successfully updated based on the judgment result in the response message; and updating the VoIP media parameters using the value to be updated for the parameter currently to be updated after determining that the parameter has been successfully updated.

The application relates to the technical field of communication performance testing, and provides a server media stress testing method and system, electronic equipment and a storage medium. An implementation scheme is as follows: a calling SIPp and a called SIPp send a start testing request to a sending party testing media server and a receiving party testing media server by calling an external interaction interface, the start testing request carries respective local media parameters, opposite media parameters and a session identifier; the sending party testing media server generates testing information in response to the start testing request, encodes the testing information and media data, obtains a media data packet, and enables the SIP server to send the media data packet to the receiving party testing media server in the form of an RTP stream; the receiving party testing media server receives and analyzes the media data packet, obtains analysis data, tests the RTP stream based on the analysis data, and generates a media stress testing result. The application can improve testing granularity and testing quality.

The application discloses a kind of based on unified port's SIP and RTP tunnel encryption forwarding method and system.The method is cooperated by tunnel client deployed in client side and tunnel server side of server side, including: based on unified port, establishing encrypted communication tunnel between the two;Tunnel client receives SIP signaling, modifies media connection information in it, and then sends to server side through tunnel encryption, and is forwarded to SIP server by server side;Tunnel client receives RTP media stream, and then sends to server side through tunnel encryption after additional header containing forwarding destination information is encapsulated, and is forwarded to SIP server according to header information by server side.The application tunnels and encrypts transmission of SIP signaling and RTP media stream through single port, effectively avoids network protocol ban, greatly simplifies firewall configuration, significantly improves NAT penetration success rate and communication security.

This invention belongs to the field of building intercom systems, specifically a method for an indoor unit to forward network camera video to a mobile app. The method includes the following steps: S1: The indoor unit locates a network camera on the same network as the indoor unit and adds it to the indoor unit's network camera list; S2: The indoor unit registers with the SIP server using account sip1; S3: The mobile app also registers with the SIP server using account sip2. This invention uses the indoor unit's RTSP to retrieve network camera data and forward it to the mobile app. It can monitor both the indoor unit and the network camera, and allows for real-time switching, effectively solving the problem that residents' mobile apps cannot monitor network cameras in public areas of the community, and also resolving the issue of residents needing to install different manufacturers' apps when using different brands of network cameras.

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.
