Hello all, Lets first mention the amazing peace of code (with respect to quality, stability and flexibility) you've all delivered with FreeSWITCH. FreeSWITCH also took our attention and we're currently investigating the possibilities for integration with our existing software suite. We're delivering a software suite with comprehensive contact center alike functionality (e.g. advanced / skill-based call-routing including IVR + VoiceMail) and call monitoring. A part of that is also call handling by so-called operators which can pick calls from queues and route them to employees. All call monitoring / manipulation is done via (propriety) CTI interface (Computer telephony Interface provided by the PBX. We're currently supporting a couple of traditional PBX'es and two IP-PBX'es. We would now also like to integrate FreeSWITCH within our Suite, first only using part but on longer term providing a complete solution: the Suite with IP-PBX. I've some questions to your developers with respect to 3rd party call control / CTI possibilities towards FreeSWITCH. Let's first give a quick overview of the call manipulation commands and expected call events that are required: ================== Commands ------------ MakeCall AnswerCall (support depends on if endpoint supports this) ClearCall Hold / UnholdCall ConsultationCall (can be part of Hold + MakeCall) TransferCall (as well blind as attended) ConferenceCall Events (device-based or call/connection-based) ------ Idle Alert/Ringing/Delivered (incoming = true or false, original called party = xxx [in case of forwarding/redirecting]) Connected Disconnected/Cleared (drop initiator = xx) Transferred (transfer initiator = xx) Held (held initiator = xx) Conferenced Failed (cause = xxxx) ========================== What are your suggestions about FreeSWITCH and the CTI interface? What is the best starting point for us to have our application connected/hooked to FreeSWITCH so that we are able to identify the call events and can manipulate the calls as given in example above? Our application suite is developed in .Net and C/C++ and (currently) windows platform only. With regards, EiSl
