In fact, the essence of the light-mouth board is equivalent to NAT device. To achieve NAT penetration, there is no problem with the SIP processing of the optical orifice plate.
Firewall is a passive network security defense technology, located at the boundary of the network, executing the access control policy between the two networks, preventing the external network from illegally accessing the internal information resources, or preventi

Tuto: Modification of a dialer
Hello everyone,
This tuto allowing to intervene directly on the resources of your dialer. ie DLL.
Advantages: no additional resource, only those origins. So, not one gram of fat added. a
This tool is a real-time analysis of the SIP Communication Protocol, which is the main function of the Communication Engineering of zhongzheng University. In addition, the distributed design can be used to analyze cross-domain sip packets, draw a complete signaling flowchart, and control the web interface... background in view of the fact that there is no free communication protocol analysis software for th

Android4.4 Telephony Process Analysis-call record loading process of dial-up applications (Dialer)
The code in this article takes the MTK platform Android 4.4 as the analysis object, which is somewhat different from Google's native AOSP. Please be aware of it.
The call history of the Android system is stored in the CALS table of the contact database contacts2.db. When the call record (calllog) is stored in the database, you can view my previous blog
