VoIP gateways convert analog and digital signals for transmission on an IP network. Likewise, a VoIP gateway can translate IP telephony into analog or digital transmissions. The gateways provide upwards of dozens of ports, with connection types such as FXO, FXS, T1, BRI and GSM.
Deploy a VoIP gateway to facilitate telephony between an IP PBX and analog phones, for example. Or utilize existing PSTN lines as failover solutions, should your primary VoIP phone system encounter downtime. VoIP gateways typically provide greater management and more features than smaller form ATAs or VoIP adapters.
