FAQ
How many analog phones can I connect to the HT818 gateway?
The Grandstream HT818 supports up to eight analog phones simultaneously through its eight FXS ports. Each port uses a standard RJ-11 connector and provides a dedicated SIP line for VoIP connectivity, allowing you to connect traditional desk phones, cordless phone bases, or other FXS-compatible devices without requiring individual adapters for each endpoint.
Does the HT818 support Power over Ethernet (PoE)?
No, the HT818 does not include Power over Ethernet capability. The device requires a standard AC power adapter for operation. This design choice keeps the gateway compact and cost-effective while maintaining compatibility with most office power infrastructures where PoE switches may not be available.
What network speeds does the HT818 support?
The HT818 features Gigabit Ethernet technology with auto-negotiating 10/100/1000Base-T ports. This ensures compatibility with both older Fast Ethernet networks and modern Gigabit infrastructure, providing optimal data throughput for VoIP traffic while maintaining backward compatibility with existing network equipment.
Can I use the HT818 with fax machines or modems?
Yes, the HT818's FXS ports are compatible with analog fax machines, modems, and other traditional telephony equipment. The gateway converts analog signals to VoIP packets, allowing these devices to operate over IP networks. This makes it particularly useful for businesses that need to maintain fax capabilities during VoIP migration.
What is the physical size of the HT818 gateway?
The HT818 measures 4.72 inches in width, 7.09 inches in depth, and 1.42 inches in height, with a weight of approximately 12.56 ounces. This compact desktop form factor makes it suitable for placement on office desks, network shelves, or in equipment cabinets where space is limited, without requiring rack mounting hardware.
How many Ethernet ports does the HT818 have?
The HT818 includes two Gigabit Ethernet ports using RJ-45 connectors. These ports support flexible network configurations, typically with one port for WAN connection to your internet source and the other for LAN connection to your local network devices. Both ports operate at 10/100/1000 Mbps speeds with auto-negotiation for optimal performance.
