some routers provide a sip proxy for that, its a common problem with sip.
other things that need that kind of feature, ie two way comms utilize upnp, ie games.
but as Doktor has pointed out, the way that a router hides your PC from the internet is to stop you getting
continually hacked.
presenting a server on the internet requires some serious thoughts about security, something that a workstation is not really appropriate for.
as in general its running two many services that make it more vulnerable to exposure.
therefore workstations should be ideally kept off direct access from outside.
