The terrestrial trunked radio gateway further includes a pulse code modulation (PCM) driver that inserts an algebraic codebook excited linear prediction (ACELP) voice data for transmission to tetra network. A user agent server (UAS) or a user agent client (UAC) connects to the VoIP phone via a VoIP network. An access net gateway (AGW) functions as an access net common application programming interface (ACAPI) client communicating with an access net common application programming interface (ACAPI) server. The terrestrial trunked radio gateway works as a signaling gateway and allow communication between the VoIP phone and a mobile radio terminal. The VoIP phone uses a built-in algebraic codebook excited linear prediction (ACELP) codec to convert voice captured into the ACELP formulated data before transferring to tetra gateway."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Terrestrial trunked radio gateway","description":"A terrestrial trunked radio gateway includes a conference server configured to perform switching of audio input from a voice over internet protocol (VoIP) phone.
