There are some new modules for OpenSER 1.2 and 1.3. I didn't have enough time to research and write about them, but they are "on the radar". I will present an introduction to some of them below.
Carrier Route first appeared in version 1.3.x. It is like a super LCR, allowing you to connect to a provider with a lot more features and speed compared to LCR. According to the documentation, it scales to several million users and is able to handle many thousand routes. It is a must-read for VoIP providers.
The dialog module introduces dialog awareness to SIP proxy. The first practical use is to discover the number of active dialogs (calls). The module does not export any functions but makes available several statistics. Another use for this module is as a base for dialog information. Load the Dialog module in your script, make some calls and see the difference in the openserctl moni
command output.
