Hi All,
I am using Kamailio 4.1 as SIP proxy and registrar with websocket and msrp
modules. As a client I am using the JsSIP stack. The client can open websocket
for SIP messages by calling "new WebSocket('ws://1.2.3.4:8000','sip')" with sip
as a subprotocol, this works fine. But when the client tries to open a
websocket for MSRP sessions using new WebSocket('ws://1.2.3.4:8000','msrp') in
the browser log I see the error 'WebSocket connection to 'ws://1.2.3.4:8000/'
failed: Unexpected response code: 400' . For MSRP file transfer I am using the
crocodile msrp lib.
The HTTP GET request of sent by the client is:
GET / HTTP/1.1

In the log of Kamailio I see these lines:
11(2114) WARNING: websocket [ws_handshake.c:318]: ws_handle_handshake():

So, anyone has an idea whats the problem is?
