In order for external access to succeed, Communicator Mobile needs to use TLS transport. By default, port 5061 is used, but other ports, such as port 443, can be used for external access. Communicator Mobile clients must be configured to include the port information in the server address. The correct format is :. For example, the client should be configured to use sip.contoso.com:443 as the external server address if the Office Communications Server 2007, Access Edge Server has been configured to use default remote client access settings. For more information about this port configuration on the Edge Server, see the Microsoft Office Communications Server 2007 Edge Server Deployment Guide.
