■ Operation of SIP-capable telephony software (see also SIP Telephony starting
on page 66)
■ TC system networking using Q.SIG-IP via VPN connections (see also PBX Net-
working starting on page 92)
■ Setting up a DECToverIP network lets you use existing Ethernet cabling to set
up a DECT network. The special DECT base stations designed for this purpose,
can be handled using Aastra 800’s Web interface (see DECT over IP® starting on
page 82).
Integrating voice and data communication within the Intranet can provide savings
possible and a range of new possibilities. However joint usage of existing network
infrastructure may also cause conflicts, with IP address configuration via DHCP for
example (for details see Start Procedure starting on page 74). You should therefore
always plan the use of VoIP in the Intranet together with your network adminis-
trator. In order to avoid possible conflicts please also note the information under
Fundamentals starting on page 62.
7.1 Quick Start
7.1.1 IP System Telephony
VoIP system telephony can be quickly and easily set up using the Aastra 800.
1. Go to the page Telephony: Devices: VoIP Telephone and click on New. Enter
the MAC Address printed on the underside of the IP system telephone. Select
the Type and enter an internal Number. Option: enter an IP address from the
Aastra 800 IP network which is not being used. Click on Apply.
2. Connect the IP system telephone’s LAN connection to the LAN and connect the
phone to the mains power using the power supply unit provided. Alternatively,
activate Power-over-Ethernet function of your PoE-cable switch or attach an
PoE injector.
Note: Use a shielded CAT-5 Ethernet cable (STP cable,
Shielded Twisted Pair cable) to connect an IP telephone to a
Local Area Network (LAN).
