System functions and features as of R3.0

6. 5. 3. 3
Call to the public Network via an operator console
Dialling via a line key of Company A routes the call via Route 1.
Dialling via a line key of Company B routes the call via Route 2.
6. 5. 3. 4
Call to the public network via SIP network interfaces
For outgoing calls via SIP network interfaces the communication server must al-
ways send the complete call number. The end of dialling is signalled using the end-
of-dialling character (#). If it is missing, the communication server will delay the di-
alling by approx. 4 s. Using a country-specific external numbering plan, the com-
munication server is able to dial out immediately on outgoing SIP connections
even if there is no end-of-dialling character (#).
The predefined external numbering plans are defined in country-specific editable
txt-files and stored in the
data/enp
folder in the communication server's file system.

Call to a virtual Network PISN User
The virtual network PISN user is integrated into the PISN via the public
network. The call to a virtual network PISN user is therefore routed via the public
network.
The PISN user must be created in the internal numbering plan. The caller dials the
PISN user number.
The routing information on the PISN users is allocated to the user configuration
and includes the route to be used and the phone number under which the destina-
tion user can actually be reached (the phone number is indicated without ex-
change access prefix). In the following example the PISN user with phone number
440 can be reached in the public network under phone number 333 33 40.
