Seamless integration of legacy applications

CERTIUM® GATEWAYS provides seamless integration of legacy applications into IP infrastructures, which enables phased migration scenarios. Support of all common interface types from analog to TDM allows radios, VCSs and telephony systems to be connected to IP infrastructures. Gateways can be used as standalone solutions or in combination with CERTIUM® VCS and CERTIUM® RADIOS.

The gateways can be used as an interface between any legacy analog/TDM to VoIP ED-137 compatible system. When connecting two legacy systems via an IP network, two gateways may be used to provide an analog or TDM link.

When combined with CERTIUM® MANAGEMENT, the gateways can be centrally managed, providing much faster deployment and easier operation.
