Suggestions for interference-free VoIP phone?

I'm looking for a corded/cordless phone that can be used with my home VoIP system and 802.11g WiFi router.

I use AT&T CallVantage VoIP service (that I like) that includes a D-Link telephone Adapter (from CallVantage)  and a Linksyn 802.11g router. 

I want a good phone system that combines (1) a corded phone “base station” that includes (a) a phone attached with a cord (duh!), (b) a speakerphone, (c) a headphone jack, (d) a nice-to-have-feature:  an answering machine that can record long conversations -- for when I'm conducting interviews -- and (e) operation on 5.8GHz so it doesn't interfere with the 2.4GHz WiFi system.

Interference problems

AT&T CallVantage tells me that a digital phone won't work well when used in combination with its VoIP Telephone Adapter and a WiFi router.  AT&T says I need an analog phone.

I have been on conversations with several people who use cordless phones with their home VoIP/WiFi network and the voice quality is often poor.  My old analog corded phone works just fine but I want a corded/cordless systems.

I'd consider two 5.8 GHz cordless phones if the quality was superb and at least one phone included a headphone jack and speakerphone.

Not easy to find

Most of the phones I've seen are (1) digital and/or (2) operate at 2.4GHz and/or (3) don't have the features I want.

AT&T doesn't have an acceptable system.  I assume lots of VoIP users with WiFi -- especially home office users -- would love to get a full featured corded + cordless phone system that would work well.

Anyone have any suggestions for such a system?  Are there any phone systems, even business phones from Nortel or other companies, that would work on my simple (non-PBX) home system?

Good comments about suggestions for interference free VoIP.

This is an excellent topic. I really think that VoiP Services will replace most phone companies.

Hi Paul,

I did find a phone set: Uniden CXAI5198 (5.8 GHz).

I have two phones: One is a corded/cordless that looks just like a regular full featured phone (the handset is attached with the typical cord to the base) that includes an antenna -- that I plug into my CallVantage TA, and the second phone is a regular cordless phone with a charging base.

The corded/cordless phone has a three-line monochrome screen, an answering machine (that I don't use) and typical features such as hold, mute and intercom with the other unit.

It works just fine for me. The call quality is generally as good as a landline. I've used it with 3M bps Verizon DSL and 5M bps (or is it 6M bps) Comcast cable modem and it has performed without a problem.

I don't know, though, whether Uniden continues to make this model.

Yeah ... I'm also looking for a cordless phone that can be used with my home VoIP system and 802.11g WiFi router.
