+ * ******** TCP implementation changes needed

+ * \todo If tcpenable=yes, we must open a TCP socket on the same address as the IP for UDP.

+ * \todo We need to test TCP sessions with SIP proxies and in regards

+ * \todo transport=tls was deprecated in RFC3261 and should not be used at all. See section 22.2.2.
+ * \todo If the message is smaller than the given Content-length, the request should get a 400 Bad request
+ *       message. If it's a response, it should be dropped. (RFC 3261, Section 18.3)
+ * \todo Since we have had multidomain support in Asterisk for quite a while, we need to support
+ *       multiple domains in our TLS implementation, meaning one socket and one cert per domain
