Enterprise Media Gateways

Businesses have migrated to IP-based communications systems to improve collaboration and contain costs.  But many enterprises still maintain large collections of legacy gear––TDM access equipment and phones along with analog lines for elevator phones, door phones, alarm systems, and fax machines.  For most large organizations it simply doesn’t make good economic sense to move every device to IP.  Ribbon’s Enterprise Gateways deliver pragmatic solutions to network transformation.  With Ribbon, enterprises can easily adopt IP-based devices and services where it makes sense while maintaining legacy access nodes and endpoints where cost or other factors dictate.
