Upnp Mapping Lines (For Remote Phones) - Aastra 55I IP PHONE - RELEASE 2.1 User Manual

UPnP Mapping Lines (for remote phones)

Universal Plug and Play (UPnP) is a standard that uses Internet protocols to enable
devices to be plugged into a network and automatically know about each other. With
UPnP, when a user plugs a device into the network, the device configures itself,
acquires a TCP IP address, and uses a discovery protocol based on the Internet's
HTTP or HTTPS URL to announce its presence on the network to 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, port
mappings are set up between the phone and the Internet Gateway Device (IGD) in
your network. The phone controls the opening, closing, and polling of ports on the
IGD. 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 this
configuration using the Aastra Web UI at Basic Settings->Preferences->UPnP
Mapping Lines.
Note: UPnP must be enabled on your remote phone before you can configure
the UPnP mapping lines. Contact your System Administrator for more
information.
