Hi there. I'm trying a scenario in which FreeSWITCH sits between a WebRTC endpoint and an IMS network, performing media conversion. When a call is established, FS starts to send INFO requests with an application/media_control+xml body related to RFC 5168. The WebRTC endpoint always responds with 415 Unsupported Media Type (the web application uses sip.js) and the IMS network sometimes responds with 500 Server Internal Error. The problem I have is that FS sends that request every second to both sides and keeps doing so for as long as the call is answered. My question is whether it would stop or at least scale down the frequency if both sides replied with 200 OK, or alternatively if there is a way to disable the sending of these requests. I've looked at the documentation and the mailing list history but couldn't find anything conclusive. Thanks in advance.
