VoiceGATE SIP
VoiceGATE SIP is a device based on the SIP protocol
(Session Initiation Protocol) that guarantees the
interoperability with a larger number of Telecom
operators using this protocol to offer VoIP telephony
services through the Internet connection.
It is possible to carry out applications with free of charge
calls between VoIP users and with very advantageous
rates in case of calls to the PSTN or to the GSM network.
This innovative technology is often associated to
softwares to be installed on your computer; with
VoiceGATE SIP you will be able to carry out the same
functionalities but using the traditional phones (analog
or ISDN) without depending on the computer and always
having the service available.
Built-in 10/100 switch.
VoiceGATE SIP has got a 3 or 4 ports 10/100 switch
depending on the version. This allows you to directly
connect the computers of your network to the VoiceGATE
SIP with better performances.
