AirLive VoIP-440S je vrlo kvalitetno i pristupačno rješenje VoIP gatewaya koje nudi vrhunski kvalitetu zvuka i fax u realnom vremenu preko IP mreža. Ima ugrađenu IP sharing funkciju tako da korisnici mogu koristiti jednu internet liniju i za razgovor i za prijenos podataka. Budući da podržava SIP protokol u proxy obliku, VoIP-440S je kompatibilan sa Cisco ATA-186 i većinom proxy usluga diljem svijeta. VoIP-440S dolazi sa 2 FXO i 2 FXS ulaza za spajanje telefona ili fax uređaja, čime pretvara običan telefon u IP telefon. Kako bi se olakšala instalacija, zajedno sa WAN ulazom, gateway sadrži ulaz sa DHCP podrškom. Na taj način samo pojite vaš PC, automatski dobijete IP adresu i uređaj je spreman za konfiguraciju u web sučelju.
