Flawed solution
By R. Cane Questions
At first, the HT-502 worked like a charm. It was simple to set up, the two ports worked in tandem without a hitch, and all seemed right with the world.About 2 weeks into ownership, suddenly one or both ports started losing SIP registration and failing to reacquire it: i.e., phone service would suddenly terminate, at times mid-call. The various VOIP forums had a number of complaints of similar behavior. Corrective actions that seem to have been successful for other users failed for me. Upgrading the firmware from the stable version (from 2010) to a new beta version made no change at all. Grandstream support has not responded to a ticket.Additionally, quality of voice service began deteriorating. Echo cancellation stopped canceling echos. High frequencies became horribly distorted and clipped. And calls started breaking up, as if I were using AT&T Wireless service when not standing directly beneath a cell tower.I could have lived with loss of registration -- painfully, but power-on resets aren't that difficult -- except that the last time the circuits dropped, the whole unit failed. It will not power on; its LEDs are blind; I am without phone service on two lines.Alas, Grandstream seems not to offer a warranty, and I'm 2 weeks beyond the point where Amazon will accept a return. I aim to replace the unit, but am unwilling to take the risk with another Grandstream. A six-week lifespan for a phone switch is unacceptable.Even if it's just this unit that's a lemon, support for it is abominable.

Wonderful device used with Callcentric
By Hue Bell
Call quality is great (so is Callcentric, BTW). I recently purchased this device for use with a voice over IP calling service. I considered the Linksys models but noticed some had issues, resets, etc. This unit has been flawless. It was running within minutes and has not hiccuped in the time I've had it. I eventually hooked it up to my home circuit (disconnected from local telco) and have enjoyed never thinking about the device. If not for a reminder from Amazon, I would have forgotten it. That's the sign of a great product. And, as always, Amazon's service was #1.

Works well and low cost
By M. Reynolds
Purchased to replace a flakey HT503 that would keep losing its registration for no apparent reason. The 502 with the same settings has run flawlessly in it's place and has not lost server registration so I am very happy. This a budget priced unit that we use often as an ISP that sells VOIP services to the public for 19.95 per month. We have tons of them out there along with some other solutions from other vendors but are pleased with the Grandstream product line. The call quality on a decent speed high speed connection is as good as standard POTS lines. No one knows our clients are using VOIP unless they mention it. I had a rather poor quality Huwei cell phone on Cricket service and the voice quality was poor, but when I used my home line on the 502 people could not believe how clear I was comparatively so they work fine despite the low cost and if they die, they are cheap and quick to replace because you can bacxk up the config and just upload it to the replacement.
