Also bear in mind that we are looking at TLS. When it comes to security, we make sure that we shall cover TLS security on it for Linphone has such in its SDK. You need to enable it. Last but not the least, on Linphone SDK, we should tune the SIP registration in a way that it supports the re-registration consecutively After you implement the call kit when a call comes, candidates must create the program in the application to handle the call kit through notification where it shall redirect the call to the application, and the SIP SDK of the application, if it's not registered, will register, and initiate the answer. But if it is registered, then just initiates the answer. Linphone SDK: [login to view URL] Although this is the initial stage, we like to see how candidates can phase one in one week's time.
