Sonus
(a product of Ribbon Communications)
With Sonus technology, we have helped companies of all sizes to upgrade their traditional telephony systems to IP telephony. This has enabled them to benefit from all the advantages offered by voice/data convergence. Finally, our partnership with Ribbon Communications and Audiocodes, allows you to get our best recommendations on these gateways VoIP.
A gateway VoIP used in different scenarios
Convert incoming ISDN lines to VoIP
In this case, the gateway allows you to make and receive calls on the normal telephone network. This transition to Voice over IP will open new doors to the digitalization of your workspaces "Digital Workplace" and will give you the opportunity to implement new solutions of Unified Communication as Skype for Business or Teams.
Connecting a traditional PBX to the IP network:
Thus, the VoIP gateway will be used autonomously to route calls from a proprietary PBX system to the public network or to a provider VoIP. By means of this solution you will reduce your telecommunication costs. In case of failure of the SIP provider or of the Internet connection, some gateways VoIP can ensure an automatic switchover to the classical connections (ISDN, analogue or GSM).
Three solutions for connecting an infrastructure Skype For Business to the public network
The first solution
If the operator provides an ISDN (PRI, BRI) or analogue connection, it will act as a gateway and transform the ISDN/analogue signal into SIP and vice versa.
The second solution
If the operator provides a SIP Trunk, the gateway will be a SBC (Session Border Controller). It ensures security (firewall, network isolation). It will also be able to perform intelligent and dynamic routing, convert number formatting, convert from one SIP Standard to another (SIP UDP to TCP), and perform transcoding (from one codec to another).
The third solution
Provide analog ports (fax, modem, ...)
