Overview + + The module enables the handling of "Event: reg" (as defined in RFC + 3680) inside of the presence module. This can be used distribute the + registration-info status to the subscribed watchers. + + The module does not currently implement any authorization rules. It + assumes that publish requests are only issued by an authorized + application and subscribe requests only by authorized users. + Authorization can thus be easily done in Kamailio configuration file + before calling handle_publish() and handle_subscribe() functions. + + Note: This module only activates the processing of the "reg" in the + presence module. To send dialog-info to watchers you also need a source + which PUBLISH the reg info to the presence module. For example you can + use the pua_reginfo module or any external component. This approach + allows to have the presence server and the reg-info aware publisher + (e.g. the main proxy) on different Kamailio instances. + +2. Dependencies + + 2.1. Kamailio Modules + 2.2.
