Poor quality gateway
GS makes some great phones. But they should get out of the gateway business with this one. This was going into a 3CX system (which I'll admit, sucks in its own right), and it caused all sort of problems. Delays when making calls, locks up when receiving calls. Had to reboot it at least once a day.
Problem with Ethernet port
The only problem presented is that the Ethernet port does not work at 100 Mbs, but if it works at 10 Mbps
Great price, Poor Quality
Grandstream has great pricing but continues to release products with faulty firmware. Sometimes I wonder just what is going on with this company.
