We have 2 GXP-2000 dead during automatic firmware upgrade. Devices now send out only one ARP packet for default gateway resolution during boot and nothing more! We've contact Grandstream support, but they cannot help. Now we want to send devices to Grandstream for repair but they on longer reply mail! GXP-2000 was very buggy on attended call transfer, and the problem resolved only after upgrading using latest firmware. Overall GXP is OK, but customer support is terrible. Stay away from them!
Elene - We are a Grandstream distributor, if you'd care to send me your company details and contact info I will assist you in obtaining recourse from the manufacturer.

Maybe a better way to say it is "Know the limitations of the GS phones and don't try and use them outside of those limits." Don't buy ANY phone you've not tested and used yourself for use by a client. My GS phone has worked fine for years. Even if it were to fail and had to be replaced buying two is still cheaper then one of some of the others. The trick is to use them (or anyhting else) only when you know it will work. That said, the GS 100 is not the best thing to put on a receptionist's desk. I've actually had pretty good luck, even getting to exchangeemail one of thier engineers. --- Elene Kinsky <admin@mapesoft.com> wrote:> We have 2 GXP-2000 dead during automatic firmware upgrade.

If you think your experience is bad, try T.38 support on practically any ATA box. :-) Steve

Unless you're buying massive quantities of the things (in which case a failure of 2 is pretty good by my standards) you're unlikely to be dealing with Grandstream directly anyway. Go back to the reseller who sold you the phones and get *them* to deal with Grandstream. FWIW, we've got 4 sites with GXP2000s, probably a total of 50 phones now, out of which 2 have had issues - one had a dodgy power connector that meant the slightest movement would power cycle the phone, the other had a dodgy off-hook button (phone wouldn't always clear down properly). All in all, even on my relatively small sample size, that's an acceptable failure rate. In both cases, I phoned our distributor, informed them of the fault and they had a courier deliver replacement phones to us the following day, and collected the offending phones at the same time, all at no cost to us or our clients.> GXP-2000 was very buggy on attended call transfer, and the > problem resolved only after upgrading using latest firmware. > Overall GXP is OK, but customer support is terrible. Stay > away from them!What issues are you having with attended call transfer? In recent months I've gone through a fair number of GXP2000 firmware versions and I can't say any of them have had a problem with attended transfer. Regards, Chris -- C.M.

Having tried EVERY single product from Grandstream, I don't think it's fair to judge Grandstream the way people do. I'm very happy with Grandstream products. As long as you upgrade the firmware they work fine. In fact they sometimes handle NAT better than any other device that I've tried (including ALL Sipura products). Grandstream is also one of very few to support ILBC codec, and BLF-support for Asterisk. If someone has tried the same, please comment.

I agree, GrandStream does seem to become the poor man's VoIP solution - making the bar for other VoIP phones very low to pass. I believe that GrandStream have a very good chance to basically being bought by a bigger company, like what happened to Sipura. What would happen then would be that people would say: "Oh, GrandStream, Very good - after all XXXX bought them". I found that sometimes the most surprising hardware comes from non-known companies, like PerfecTone or Micronet. I think the main thing is the try things out, and find out what is the best suited IPhone for you.

Who doesn't have money to buy anything else but Grandstream, I recommend PA-1688. Cheaper and better and have IAX2 protocol embeded. Talk to my friend Jack in China.. http://www.yntx.com/ Who wants to keep defending Grandstream, please send me the address and I will ship all the broken bunch I have here... :-) On Tue, 27 Dec 2005, Elene Kinsky wrote:> We have 2 GXP-2000 dead during automatic firmware upgrade.
