Grandstream HT818 Review

Grandstream's HT818 for Asterisk Deployments with Numerous Analog Devices

Asterisk PBX salesman.When deploying an Asterisk IP-PBX with numerous analog endpoints, the best solution is a FXS gateway device that offers numerous ports. An example of such a deployment would be a facility that has offices, each with an Ethernet (RJ-45) connection for direct IP access, (the IP phone and PC can be share the line through the Ethernet phone port), but may also have a warehouse or operations area where analog phones exist and running new cables would be expensive. Cables can run anywhere from $180.00 to over $300.00 per cable depending on logistics, cieling height and if a lift would be required.

Phones in warehouse environments like these are typically distributed in various areas along walls or on vertical steel beams where employees, who don't use the phone often, take or make an occasional call. Some phones may be required by OSHA. In any event these analog phones and other devices will remain analog and be connected from a FXS (RJ-11) port (SIP to analog) connection in the phone closet. In some installations it's not unusual to have 8, 12 or more analog devices. Rather than using multiple 2 port ATAs, where two or even three would be acceptable, using a FXS gateway device with multiple ports has advantages. Grandstream's HT818 offers 8 FXS ports and has proven to be a solid cost effective solution. The HT818 offers dual Gigabit ports, an integrated NAT router and QoS for more stable VoIP services.
