Hi Inaki,

Just adding to Ranjit mentioned. The text similar to the following has to be added. "Record-route header MUST be added by SIP WebSocket Server in case WebSocket is the only supported SIP transport between SIP WebSocket client & server and SIP WebSocket server acts as SIP proxy" 

Thanks
Partha
