Customer Reviews
Supports only 10base-t network
Note that the network interface on this device is 10-baseT (10 mbs). The speed is not the issue though. I had problems with it auto-negotiating with my dlink switch. I could not get it to connect and wound up plugging it directly into my PIX router.
Other than that it works great.
Working great,perfect and cheap
I use it with CallCentric and this one work great. The sound quality is even better than landline. Setup is very easy by following CallCentric instruction. Bye bye landline,bye bye expensive AT&T.
Good basic ATA
Does the basics well but lacks advanced features like a dialplan (like the SPA2102) which means you have to wait for timeout or dial # for your call to go through. You also can't restrict dialled numbers in the ATA. If you are looking for a low cost, basic ATA, this is is.
Simple and Elegant
Hookup to my service provider Callcentric was a breeze. Didn't take much time thanks to detailed instruction from Callcentric. Call quality was good most of the times except when talking while walking, people can't hear good on the other end. Hope its not due to the product.
Grandstream for an extra line
Use it to add the house onto the office Trixbox. Very fast to setup and works great except for FAXing.
Works great!
I hooked this thing up to Gizmo5 (VoIP) and some VTech cordless phones. I have have my Google Voice (old GrandCentral) calls forwarded to it. It works like a charm, much better than my cell phone.
The only problem I had is that the STUN portion incorrectly detects my home router as unrestricted cone, when it is a port restricted cone. It correctly determines the network type and works when I take the other Grandstream device off line (BT100). Then the BT100 device has the same issue. I guess I could futz around with network settings, but otherwise only one of these Grandstream devices per NAT router.

Ken
Perfect
Very inexpensive and works perfectly out of the box with Asterisk. I've been using mine for several weeks now with 0 problems.
Great
I'm no VOIP expert and with this product you don't have to be. I had it hooked up and working in minutes and haven't thought about it since!
works great
cheap, easy enough to configure, works great.
Grandstreams are a great bargain
Originally, I bought one of the Linksys PAP2T ATAs to connect my few remaining analog phones to my Asterisk box. However, it never worked properly even after flashing the latest upgrade.
I've been buying and installing Grandstream GXP2000's in customer installations for some time. They are just so easy to get working with Asterisk. So, I thought I'd give their ATA a try.
Very nice. Same web based interface, with adaptations for the analog part of the system, made me feel right at home. Less than 3 minutes after opening the box, and it was up and registered.
The Linksys had been giving me fits with dropping calls after 2-3 minutes. The Grandstream is rock solid! The price difference made it a nice investment, as well.
Grandstream gets a bad rap
Why pay the extra money for Linksys? I have found the Grandstream adaptors to be very dependable and easy to work with.
