Network-network-network  I've sold and used them personally for about a year now.  The Network is everything.  Their soild on the right network or can be hell  on the wrong ones. (some cisco systems).  Also Asterisk is not a proxie or a switch. Some things don't work (like call forking.)  I'm a sip provider and I like Sipura a lot better but the 3000 has problems with Asterisk.

Grandstream products have a one year warrantee.  If you can show (with
invoice or otherwise)that your product is in warrantee we will exchange it,
regardless of where you bought it. All we will charge you for is shipping.

Subject: RE: [Asterisk-Users] Grandstream ATA 286 problems

	Hi,

Well, in my case I have a 486 and a hell lot of the problems with that.

First I have not being able to use "features" like call transfer or anything
like that (built-in ones) - it will just not respond to those commands. And
Grandstream sent me a reply to my problem
saying: "this is the problem with your * configuration and those features
are not supposed to work without Asterisk". But eventually with the latest
firmware I've managed to make it work after some voodoo. But the new
firmware introduced another issue, which is kind of weird: my ADSL modem
will resync every 10-15 min if I connect Grandstream ATA 486 to PSTN (do not
get me wrong, I really put the ADSL filters in). As soon as I remove ATA
486, ADSL stays solid and does not resync.

In your case you would just get a bounce backs from grandstream to your
vendor and back, but in my case vendor will just not respond at all to any
communication means. So beware VOIPSUPPLY.COM seems to be a bunch of funny
people who will not stand behind the products they sell. 

So in my case I not just made a worst purchase, but also choose a worst
supplier.

Sincerely,

I contacted the vendor I bought it from, and they said to contact 
Grandstream.

I contacted Grandstream, and they told me to hit refresh in my 
browser....

After sending them the Ethereal trace, I haven't heard back from them 
yet.

I think it's the worst purchase I've ever made.
