If you are planning on setting up several "remote" phones at one location, then the Proxy Manager is probably the best way to go, it can eliminate a lot of headaches.
If it's just one set, and the set has a STUN setting, then there should be no issues. Of course, problem can arise due to many factors that may be unique to your particular installation, including the type/make/model of router that the set is behind and other devices on that network.
