Does anyone know whether it's possible to program a softkey on an 8800 series 3pcc phone to do some HTTP action, e.g. send a POST, GET, or PATCH request? Or, to show an XML application where a user could initiate such an action? We're trying to set up a "Record" softkey to start call recording, which our server initiates by an HTTP REST endpoint (POST request). Would appreciate any guidance or examples, or if it's not possible let me know. I know the old 7900 series used to support XML apps but can't find much documentation around this for the 8800 series.
