IP telephones and VoIP trunks
This section describes two similar applications for IP telephony on the Business Communications
Manager system: IP telephones and VoIP trunks. These applications can be used separately or
together as a network voice/data solution.
Refer to the information under the following headings:
• IP telephones
• VoIP trunks
IP telephones
IP telephones offer the functionality of regular telephones, but do not require a hardwire
connection to the Business Communications Manager. Instead, they must be plugged into an IP
network which is connected to the LAN or WAN card on the Business Communications Manager.
Calls made from IP telephones through the Business Communications Manager can pass over
VoIP trunks or across Public Switched Telephone Network (PSTN) lines.
Nortel Networks provides two types of IP telephones. The IP telephones are wired to the IP
network using Ethernet, in the case of the i-series 200X IP telephones, or are accessed through
your desktop or laptop computer, as in the case of the Nortel Networks 2050 Software Phone. For
configuration information, refer to “Installing Nortel 20XX IP telephones” on page 43.
Emobility voice can be provided using the WLAN IP telephone 2210 or 2211. These handsets
connect to the IP network through an 802.11b compatible access point. A SVP (2245) server
provides the telephony call processing between the handset and the Business Communications
Manager. An optional TFTP server provides a way to upgrade the firmware in the handsets.
Installation and configuration information for this system is covered in a separate installation and
configuration document.
