The IP terminal interfaces are implemented via an Ethernet interface on the com-
munication server. Besides IP system phones Aastra 400 also supports Aastra SIP
terminals and standard SIP terminals by other manufacturers.
Fig. 15 IP terminal interface
Like the digital system phones the IP system phones (softphones and desk phones)
communicate with the communication server via the AD2 protocol. Unlike digital
system phones, however, call and signalling data is transmitted in the IP network.
The devices are connected to the IP network.
The media data from SIP terminals is processed into packets using the SIP protocol
and transmitted using the RTP protocol. Corded SIP desk phones, SIP softphones as
well as WiFi mobile phones connected with the IP network via an access point can
be operated on an Aastra 400.
The number of terminals on the IP user-network interface (Ethernet) is determined
by the system limits on the one hand and by the number of licences on the other.
