* #27232: jni: added pjproject checkout as regular git content
We will remove it once the next release of pjsip (with Android support)
comes out and is merged into SFLphone.

+ * The STUN transport provides asynchronous UDP like socket transport
+ * with the additional STUN capability. It has the following features:
+ *
+ * - API to send and receive UDP packets
+ *
+ * - multiplex STUN and non-STUN incoming packets and distinguish between
+ * STUN responses that belong to internal requests with application data
+ * (the application data may be STUN packets as well)
+ *
+ * - DNS SRV resolution to the STUN server (if wanted), along with fallback
+ * to DNS A resolution if SRV record is not found.
+ *
+ * - STUN keep-alive maintenance, and handle changes to the mapped address
+ * (when the NAT binding changes)
