Even with STUN servers in use it ispossible that the connection will not work, as some typesof NATs still block the traffic.The settings for NAT traversal can only be provisioned bythe service provider, for example over the air or viadownload, but cannot be edited manually by the user.Unlike the SIP settings and Internet call settings, the NATsettings cannot be defined manually, and it is thereforerecommended to use provisioning offered by Internet callservice provider.NATThere are two types of network address translation.The type often popularly called simply NAT (also namedNetwork Address Port Translation or NAPT) refers tonetwork address translation involving the mapping of portnumbers, allowing multiple machines to share a single IPaddress.
