+	  <p>PJProject has a limit on the number of TCP connections
+	  that it can accept. Furthermore, PJProject does not close
+	  TCP connections it accepts. By default, this value is
+	  approximately 60.</p>
+	  <p>An attacker can deplete the number of allowed TCP
+	  connections by opening TCP connections and sending no
+	  data to Asterisk.</p>
+	  <p>If PJProject has been compiled in debug mode, then
+	  once the number of allowed TCP connections has been
+	  depleted, the next attempted TCP connection to Asterisk
+	  will crash due to an assertion in PJProject.</p>
+	  <p>If PJProject has not been compiled in debug mode, then
+	  any further TCP connection attempts will be rejected.
+	  This makes Asterisk unable to process TCP SIP traffic.</p>
+	  <p>Note that this only affects TCP/TLS, since UDP is
+	  connectionless.</p>
