Hi, I've just been adding WebSocket transport support to the modules that I think need updating. I believe I have got them all except modules/sipcapture. I think the update to this module should be in sipcapture.c:hep_msg_received(), but I am not sure what change to make. The way that TLS seems to be handled here is that the HEP header uses the value IPPROTO_IDP - which seems to indicate some sort of fake protocol. Previously TLS was the only fake protocol, but WebSockets (WS) and secure WebSockets (WSS) are also fake protocols (being encapsulated on TCP and TLS respectively). Is there anything simple I can do now, or does this mean the HEP protocol will need to be updated to support WebSockets? -- Peter Dunkley Technical Director Crocodile RCS Ltd
