Figure 4.1 General scenario for CELLX Box deployment
As shown in Figure 4.1 you need to know the following:
ƒ
the local IP network the CELLX Box is integrated into: a fixed IP address, net mask and
a default gateway (already done as described in
Chapter 4.3 on page 24 ).
ƒ
the connected telephone equipment (PBX, telephones): which interface is used for
which equipment; what are the telephone numbers (internal and external) used for this
equipment?
ƒ
the VoIP configuration: You need a contract with a VoIP provider who provides public
telephone numbers, a SIP proxy and a registrar. They are needed so that incoming calls
from public PSTN network can reach the CELLX Box, and from there your telephone
equipment. Your CELLX Box must be accessible for calls from the VoIP provider.
For internal VoIP you need your equipment settings.
ƒ
the configuration of your mobile module providing the connection to the mobile
network.
