Message:

Major improvements in PJSIP to support TCP. The changes fall into these categories: (1) the TCP transport implementation itself (*.[hc]), (2) bug-fix in SIP transaction when using reliable transports, (3) support for TCP transport in PJSUA-LIB/PJSUA, and (4) changes in PJSIP-TEST to support TCP testing.
