Keep in mind that some of these devices do not provide disconnect (CPC) signal. Therefore if you put calls on hold, you might pick up and find no one there, and your line will have been unnecessarily busy during that time. In addition, if you have a voicemail system or auto attendant, you may get long periods of silence that fill up your hard drive after the calling party hangs up. Something to keep in mind.

I use Linksys/Cisco ATAs with my Merlin Legend system, providing a total of four lines, two coming from each ATA, and I have no problems at all. Voice quality is excellent. Like Meyery2k mentioned, your quality of service will depend on the quality of the company providing it.
