Is it possible? and If so, what ports should be forwarded?
I think you need to provide a bit more information on how you want to set this up.
When using the 3cxphone windows client on an external network (outside of the local lan) i.e. through the internet
Ports like 5060 are already open... so voice is working
Here is a list of the various ports used...
And another page...
And some info on port forwarding/ router configuration.
