[SR-Users] websocket rd buffer size limit?

[Andrew Chen]

So what engineering is stating is we may need to support up to 65k.  The
video feature to support more video pods will produce large SDP's.

So I got a random MESSAGE to Kamailio to work with TCP 5060 with 70k
content length but when using websocket, it's limited to 64k.
