Grandstream HT800 Series ATAs Officially Certified

Posted by Dana Meltzer on Aug 17, 2017 9:57:00 AM

We are pleased to announce that we have successfully completed interoperability testing with Grandstream’s HT800 series ATAs. Grandstream Networks, Inc. has offered SIP Unified Communications solutions since 2002, and its products have been recognized for their quality, reliability, and innovation. The HT series of ATAs delivers powerful VoIP technology and routing capabilities to home and office environments, and allows users to successfully connect their analog devices to a manageable, robust network. Built using Grandstream’s market-leading SIP ATA/gateway technology, with millions of units successfully deployed worldwide, these powerful ATAs feature exceptional voice quality in various applications and environments.


The HT800 series of ATAs includes 4 different models, giving customers the flexibility to choose the right device

based on individual deployment needs. The HT801/802 ATAs each have a single 10/100Mbs port and can support either 1 or 2 SIP profiles. The HT812/814 ATAs each have dual Gigabit ports, and both support 2 SIP profiles through either 2 or 4 FXS ports.


All of the ATAs in the Grandstream HT800 series support T.38 and can connect directly to our fax-optimized SIP trunks using our Power-T.38 service. Or they can talk to us through any SIP infrastructure that knows how to do T.38 pass-thru (Asterisk, FreePBX, OpenSIPS, Kamailio, etc.).


The Grandstream HT800 series ATAs have been thoroughly tested by our interop ninjas and work seamlessly with our Power-T.38 Fax over IP service. We’ve gathered our screen shots and recommended best practices and assembled them into our Grandstream HT800 series Knowledge Base Articles, which you can find here:

The Grandstream UCM Series IP PBXs, like most products we certify, are available for purchase from Telephony Depot.
