Introduction to Osip protocol stack (Continued 1: Pure protocol stack logic analysis)

between a dialog of a session, such as invite-100-180-200-ack is a complete transaction, bye-200 is also a complete transaction. It is reflected in the SIP message, that is, the same branch value in Via indicates that the message belongs to a transaction (of course, the transaction is in the dialog, therefore, the from and to tags and call-ID values are the same.) transactions have different terminal types and messages for UAC and UAS, which are divided into four categories, the invite transact

Getting started with Osip protocol stack (and exosip, ortp, etc.)

initialization of this development library :)To some extent, we should know where the message of the SIP application developed by Osip is sent. By the way, from this callback function, it is difficult to start with everything, just like when developing a Win32 application, it is easy to find the work under the main function entry of the Win32 program. The following are the corresponding processing functions developed for some event messages :)   Osip_set_kill_transaction_callbackTransaction ter

degrees. Grad represents the Gradians degree of the angle. A complete circle for the grad. Rad represents the Radian of the angle. A complete circle is 2π (about 57.29rad). Turn indicates a long circumference. A full circle is 1turn. Each of these units has a positive negative value indicating a clockwise or counterclockwise direction. In the following example, it is shown how to represent a clockwise 90 degree in various units. . foo { /* going clockwise * /transform:rotate (90deg);
