The primary focus of Pluggable Authentication Module (PAM) is to authenticate your users. PAM lets you set up the environment that the users will work in. And when the users log out, PAM tears down the working environment in a controlled way. PAM and PAM-aware applications reduce the complexity of authentication. Application programmers can take advantage of PAM, rather than developing a complete set of authentication functions. In this article by Kenneth Geisshirt, we will see how an application uses PAM for authentication and how to develop our own PAM modules.Read Development with Pluggable Authentication Modules (PAM) in full

PSTN or Public Switched Telephone Network is the collection of all the telephone networks, which are interconnected in the world. If we want to be able to route calls from and to the PSTN using OpenSER, we need to be connected to a PSTN. To send calls to the PSTN, we need a device called PSTN gateway. There are several manufacturers such as Cisco, Nortel, and others who manufacture this kind of equipment. You can also use an Asterisk PBX box for this task. Asterisk makes an affordable PSTN gateway that is very competitive with the big players mentioned above. In this article by Flavio E. Goncalves, we will see how to use asterisk as a PSTN gateway for OpenSER.Read Using Asterisk as a PSTN Gateway for OpenSER in full
