When packet arrives at from the WebSocket its length usually more that 1500
THat is the problem. sometimes sdp data lost while sending. If asterisk at
the sama machine it uses lo interface and then it is not a problem but for
remote servers it can be.

I didnt thought about keepalive. I suppose it can help.
