The Grandstream GS-HT814 v2 is a 4-port VoIP gateway with dual Gigabit ports and a built-in NAT router, suited to small offices that need multiple FXS connections and support for two SIP profiles.
Recommended For
- Home-office or small-office users who want to keep up to four existing analog phones and connect them to SIP-based phone service.
- Small businesses using a compatible PBX that need to connect analog desk phones, fax machines, or other FXS-compatible equipment to a VoIP system.
- Organizations migrating from analog fax equipment that have a SIP provider and fax setup compatible with T.38 or fax pass-through.
- IT or telecom teams deploying multiple analog endpoints who can use web-based configuration, SIP provisioning, or a Grandstream UCM system to manage setup.
Real-World Use Scenarios
- A home or small office moving to SIP service can keep using compatible corded or cordless analog phones by plugging them into the HT814; calls then use the configured VoIP service instead of a traditional phone line.
- A small office replacing or extending its phone system can connect several existing analog phones to a VoIP PBX or hosted phone service, keeping familiar handsets in use while routing calls through the new system.
- An office that still uses a fax machine can connect it to an FXS port and send faxes over a compatible VoIP service; reliable results depend on the fax provider and configuration supporting T.38 or pass-through.
- A small business using a Grandstream UCM PBX can add analog phones or a fax machine through the HT814 and provision the gateway as part of that phone system, reducing the need to replace every analog device.
- A home or office with multiple analog handsets can use the adapter’s ports for VoIP calling and, when configured for the service, use handset features such as call waiting, call forwarding, or three-way conferencing.
