Ticket #407 added keep-alive mechanism in PJSUA-LIB. Here we only enabled keep-alive when STUN is enabled, since we thought that keep-alive is only needed in Internet situation. But it has been discovered that Windows Firewall on WinXP also needs to be kept-alive, otherwise incoming packets will be dropped.
Thanks Andreas Backman for reporting this.
