VoiceBlue Enterprise
1.1. Purpose
•
The 2N VoiceBlue Enterprise gateways provide direct
interconnection of VoIP and GSM networks with the aid of SIP
signalling protocols.
•
The voice mode, i.e. an outgoing or incoming call, is the basic
function of the system. The gateway is equipped with all
functions necessary for such use and provides a very high
comfort in this mode.
•
In addition to voice transmission, 2N VoiceBlue Enterprise can
send and receive short text messages. For remote control
purposes, diagnostic SMS can be sent in regular intervals from
the gateway to a selected mobile number. These additional
functions enhance the utility value of the product.
•
2N VoiceBlue Enterprise contains a built-in SIP proxy server
and can thus serve as a PBX for SIP telephones. However, the
use of the gateway is not limited to this SIP proxy function
only, it can be applied with any SIP supporting PBX.
•
No extra equipment (an external GSM telephone, etc.) is
needed for normal operation. All programmable parameters are
default-preset in such a manner that you can commence your
telephone traffic the moment you connect the Ethernet and
supply cables, antenna and SIM card and set the IP parameters.
1.2. How to Save Telephone Costs
•
Once your 2N VoiceBlue Enterprise gateway has been
connected to your VoIP PBX, all calls going out to a mobile
network are made directly. This saves your PSTN - mobile
network call costs. The mobile telephone calls of your
personnel in the field are cheaper too.
•
You are advised to use the most advantageous tariff of your
GSM provider for your GSM gateway because all gateway
user call accounts are added up for billing purposes.
•
If you use a call answering machine as a GSM network
service, you pay for your voice message deliveries as a rule.
However, if you connect your answering machine to the GSM
gateway, you pay nothing for your voice message deliveries.
