IP Phone Administrator Guide

You can enable UPnP on remote IP phones using the configuration files, the IP 
Phone UI, or the Aastra Web UI. Using the configuration files, you can enable 
UPnP using the following parameters:

The “upnp manager” parameter enables or disables UPnP. The “upnp gateway” 
parameter is the IP address or qualified domain name of the Internet gateway or 
router that stores the port mappings. In the event a phone using UPnP is rebooted, 
it will still have the previously set port mappings on the gateway. The “sip nat rtp 
port” parameter specifies the RTP port range on the gateway.

A User or Administrator can specify UPnP on specific lines using the 
configuration files (using the “upnp mapping lines” parameter) or the Aastra 
Web UI (at the path Basic Settings->Preferences->UPnP Mapping Lines).

For more information about enabling/disabling UPnP Mapping on specific lines, 
see Chapter 5, the section, 

Use the following procedures to configure UPnP on the IP phones.

For specific parameters you can set in the configuration files, see Appendix A, the section, 

on 

page A-25.
