3.1 Overview: Using ECOTEL
ECOTEL ® has interfaces to various networks: GSM, ISDN (and
also VoIP with ECOTEL ® VoIP). Its main function is to route calls
between these networks based on different parameters in a
routing table.
On the ISDN side, ECOTEL ® is connected in most applications to
a PBX. ECOTEL ® provides additional services to the PBX and
must be configured to work with it.
Based on this general approach, there are a number of different
connections and configurations which are possible and which are
explained in greater detail in this section.
Additional functions besides routing are also described here.
Possible applications from a user perspective
Telephone and mobile phone charges have become an important
cost factor for many companies today. The cost of connecting
fixed public network subscribers with mobile network subscribers
(as well as for making VoIP calls to mobile radio subscribers) is
significant.
ECOTEL ® VoIP establishes connections from the IP network or
ISDN fixed network to GSM mobile networks. Consequently, you
can take full advantage of the more favorable rates that are
available when your calls remain within the mobile network.
ECOTEL ® VoIP can route incoming and outgoing GSM calls to the
Ethernet connection (VoIP) as well as to the ISDN basic rate
interface (S0 bus). The SIP protocol is used for calls via the IP
network (LAN or WAN).
ECOTEL ® ISDN2-1 and ECOTEL ® ISDN2-2 lack the IP connection
for telephony and thus do not offer VoIP connections. Otherwise,
they are the same as ECOTEL ® VoIP.
