What is BVA8053?
BVA8053 Series Broadband VoIP Adaptor is a cost-effective and easy-to-use gateway to the fast growing VoIP telephony services for both residential and home business uses. Just connect it between your internet and computer at one side and your regular telephone set at the other, and it is ready for you to call over internet- thanks to the Auto Provisioning System (APS). Some flavors of the BVA allow you to connect to both the Internet and regular phone line (PSTN), so that you can make phone call to both networks. The rfc3261 SIP standard conformity makes BVA work with over 95% of the VoIP telephony services.
