VoIP Gateway

VOCAL’s VoIP Gateway converts between legacy telephony connections and IP networks using a VoIP connection and SIP. Our VoIP gateway converts voice media between a digital TDM connection, such as E1, T1, or PRI (Primary Rate Interface), and the VoIP connection. The conversion can be SIP to TDM, TDM to SIP or even SIP to SIP.

VOCAL’s VoIP Gateway can also interface a legacy PBX system to  a more cost effective SIP trunk connection. The VoIP or IP Media Gateway acts as a bridge connecting the legacy system using a PRI interface and the SIP service provider using an IP network interface. Likewise the VoIP Gateway can connect a VoIP-only system to a PSTN trunk.
