Hi Mark, Unless you have good reason, then writing a custom FS module is probably not the right way to go about this - I don't think I can see anything here which you couldn't do with Lua or an event socket client. --Dave
I need to create a custom Freeswitch module that acts as a leg/endpoint of a call. Unlike a conference, it needs to maintain a UUID so that a parked call can be bridged to it. Once the call is bridged, the module will be in "connect" mode. After the bridged leg disconnects, the module goes into "data collection" mode and gets DTMF call results from the operator. It then goes into a "parked" mode, waiting for another call to be bridged to it or for the operator to hit a DTMF logout sequence.
I just need to know what I should look at for a template/sample to start with. Conferences don't seem to be applicable because they don't have UUIDs for bridging (I'd tried doing this behaviour using them and failed miserably.) The code for audio_bridge_function is interesting, but I don't believe that's what I need to start with either, as it _bridges_ calls rather than providing a virtual endpoint.
Just to make things real interesting, I'll have to have the custom module generating custom events so that the Erlang control code gets notified with the call results so it can update an RDBMS with the result code. If I decide to get fancy, I'd like to have a mini-IVR associated with it that can provide voice prompts about the result codes available to the operator.
Last but not least, I'm uncertain as to whether such a custom module needs to be "released" to the Freeswitch team, or whether it would be an "internal only" module. Hopefully it _has_ to be released -- I'd like to contribute in some small way to the community.
As a "for example", picture the tech support call center -- after each call the operator/tech has to enter a code indicating whether the call was 1) handled; 2) passed to level 2 tech support; 3) passed to level 3 tech support; or 4) scheduled for callback.
