GXW4024 predstavlja sljedeću generaciju FXS gatewaya baziranih na SIP standardu i kompatibilnih sa vodećim IP-PBXovima i SoftSwitchevima. Odlikuju ga 24 FXS ulaza, vrhunska kvaliteta zvuka, bogate telefonske funkcije, fleksibilni pozivni planovi i napredna zaštita. GXW4024 omogućuje malim i srednjim poslovnim korisnicima da stvore efikasni hibrid IP i analognog telefonskog sustava uživajući pri tome u prednostima VoIP komunikacije i istovremeno zadržavajući postojeće analogne telefone i PBX sustave. GXW4024 nudi savršeni omjer cijene i kvalitete u području gatewaya za VoIP mreže ili pri prelasku sa starog analognog telefonskog rjesenja na IP infrastrukturu. Kako bi se dobilo moćno poslovno hibridno rjesenje moguće ga je i kombinirati sa IP-PBX sustavima (GXE5024, GXE5028).
