With UPnP, when a user plugs a device into the network, the deviceconfigures itself, acquires a TCP IP address, and uses a discovery protocol basedon the Internet's HTTP or HTTPS URL to announce its presence on the networkto other devices.This method of device discovery on a network is called “Universal Plug and Play”or UPnP. If you enable UPnP, and the phone is discovered on the network, portmappings are set up between the phone and the Internet Gateway Device (IGD) inyour network. The phone controls the opening, closing, and polling of ports on theIGD. HTTP and SIP use a single port each. RTP/RTCP uses a range of ports.You can enable the UPnP mappings to specific lines on your phone. You set thisconfiguration using the Aastra Web UI at Basic Settings->Preferences->UPnPMapping Lines.Configuring UPnP Mapping LinesUse the following procedures to configure UPnP mapping on specific lines on theIP phone.Note: UPnP must be enabled on your remote phone before you canconfigure the UPnP mapping lines. For information on enabling/disablingUPnP see Chapter 4, the section, “Universal Plug and Play (UPnP) (forremote phones)” on page 4-50.Configuration FilesFor specific parameters you can set in the configuration files, see Appendix A, the section, “UPnP Settings”on page A-37.Draft 1
