Summary:                    in "_sip_tcp_helper_thread" Buffer is filled with
dirty bytes
Description: 
I've seen with aastra phones 51i and 57i that buffer "buf" is not empty
with TLS. 
I suggest to do this patch
.....
	for (;;) {
		memset(req.data, 0, sizeof(req.data));
		memset(buf, 0, sizeof(buf));  //<<<<<<<<<<<<<<<<<<< Patch
		req.len = 0;
		req.ignore = 0;
		req.debug = 0;
.....
