D2 Technologies has introduced the company’s vPort Gateway (GW) embedded VoIP software on Ralink Technology’s RT3050, RT3350 and RT3052 802.11n networking processors.

According to the company, the joint offering gives OEMs and ODMs an economical way to develop competitive advanced wireless access points and residential gateways that deliver triple-play voice/data/wireless functionality.

By optimising D2 Technologies’ vPort VoIP solutions for voice, advanced telephony and voice signaling on the RT3050, RT3350 and RT3052, we’re making it easier for OEMs and ODMs to develop best-in-class wired and wireless networking products.
