Grandstream is known for its conferencing, IP voice telephony, and networking solutions for SMBs/enterprises. Grandstream also offers a plethora of additional services including physical security and networking. The company's latest, the HandyTone Series Analog Telephone Adapter is designed to create an IP telephony hybrid solution by converting analog phones into VoIP systems.
From our assessment of the ATA, setup is easy, as is management. For businesses looking to maximize productivity and efficiency of overall communication – the HandyTone Series will more than suit your interests.
The HandyTone Series consists of:
- HT801
- HT802
- HT812
- HT813
- HT814
- HT818
These ATAs are all similar in nature. The major difference between the adapters is that the HT801 has one FXS port. Grandstream’s HT802 adapter has two.
Our review of the adapter series covers key features, advantages, pricing, as well as how to buy.

With Grandstream’s HT801, users gain access to one line, encryption security, auto-provisioning, three-way conferencing, failover protection, fax support, and caller ID. Regarding security - there is TLS and SRTP encryption which protect calls and accounts.
Failover is another piece of the HandyTone adapter puzzle. Unlike switchover, failover does not require human intervention. This means, Grandstream’s SIP server automatically switches to a secondary server if anything goes awry.
Advanced telephony features are too a possibility, including call transfer, forwarding, waiting, do-not-disturb, ‘message waiting’ indication, multi-language prompts. The UC provider, furthermore, has a flexible dial plan. The primary differentiator between HT801 and HT802 is the number of phone lines you get.
With the HT802, users can access two lines. Moving up in the Series – HandyTone's HT812 features an integrated gigabit NAT router, which increases speed. This is included at no additional cost and ultimately can lead to a more stable connection.
Its HT813 has a single analog telephone FXS port and one PSTN line FXO port for backup. The combination of FXO and FXS ports enable the adapter to support remote calling to and from ‘public switched telephone networks’ (PSTNs). Another added benefit of the HT813 is flexibility, as the FXS port extends VoIP service to one analog device.
