D-Link SIP VOICE TERMINAL ADAPTER ( DVG-2001S ) Review

Average Reviews:

(More customer reviews)This ATA just isn't very good. The web interface is incredibly clumsy and the features are limited. For the price, you can get Linksys (Sipura) ATAs that have both FXO and FXS ports and are far more capable and convenient to use, although Amazon for some reason chooses not to sell them directly.

Cisco SPA941 4-line IP Phone with 1-port Ethernet Review

Average Reviews:

(More customer reviews)I put together two Asterisk servers for two businesses, and bought several of the SPA941 phones. I looked at Grandstream products, and read reviews, and bought one, but they are basically cheap crud in comparison. This SPA941 series is a solid business phone that works well... the cheaper competitors feel like cheap plastic (they are), and have all kinds of operational issues working with Asterisk. I'm basically a fan of this product.
On the down side, I have had trouble getting and installing the 2-to-4 line upgrade. Be aware that this is only a 2-line phone, even though it has 4-line buttons.

Siemens Gigaset Digital Cordless Phone with Hybrid IP/Landline Calling (A580IP) Review

Average Reviews:

(More customer reviews)I am reasonably technical and run a VOIP PBX for our small business with several different providers, IP Phones and gateways. This seemed like a nice addition where cordless IP phones are needed. I have almost returned this several times because of the UI and contact import issues, however I am keeping it in hope of an updated firmware release.
Pros -
Good voice quality
Register multiple VOIP Providers
Price is right for an expandable VOIP based ATA and handset
Cons -
Handset Interface and Features are a mess to use - Siemens could learn something from other cordless handset manufactures
Vcard contact import is a nightmare
Can't seem to remove internal Gigaset setting/provider
Web interface is acceptable If you do the upgrade... if not it is so slow you can' use it.
No Headset Jack (are you kidding me?)
I want to like it... but not quite prime time.
