Hello all! I interests the next questions: Are Possible to use FreeWSITCH how UA? I have a task to write FreeSWITCH module (for Linux) that get an information (a signals) from another application and establishes SIP transactions (with FreeSWITCH functions) with another SIP agents. Ex: An Application sends a signal to the FreeSWITCH module (eg using a message queue), transmits the data about the caller and the called party. The module should to establish the session between them with FreeSWITCH functions. In this case voice will not be transmitted with FreeSWITCH. Perhaps this problem has been resolved already. Can are you provide me a link to a similar case, examples or documentation, how it done within FreeSWITCH (preferably a C )? Thank you very much!
