To add a couple more into the mix; Siemens S450IP - Supports up to 6 accounts and offers a similar matrix assignment to the Aastra MBU unit but only for up to 6 SIP accounts with a maximum of 3 channels but each handset can be registered to more than one base station. The KIRK system, now owned by Polycom I believe, is a highly scalable DECT system much like the RFP32 - pricey but very scalable and the KIRK handsets are very reliable also.

Aastra MBU 400 - Pretty good build quality, LiPo batteries, can handle up to 8 handsets and 8 SIP accounts. You assign the registrations to handsets in a sort of matrix, so they can all share one, or each have their own. Maximum 3 channels at a time though.
Snom M3 - Haven't tried it, but it has a lot of common components with the Aastra and a similar feature set. I think this also has a 3 channel limit.
Gigaset S675 - About half the price of the other two, but with a significant reduction in what you get. Only one SIP account across all phones, and I'm not sure that it can do 5 handsets. I think it can do at least 3.
Aastra DECT 142 handsets and RFP 32 base stations - This is a campus DECT mobility system. It's a lot more expensive, but a lot more scaleable. Each RFP32 base station can have up to 8 simultaneous channels. You can have up to 512 handsets per system, with up to 256 base stations set up in a cellular-like system. I have personally tested this system with Freeswitch and it works great. Very easy to set up. The handsets are also very durable.

Hi,
I'm looking for IP-dects where a base station can handle 5 phones (which all should be able to talk at the same time). All suggestions are welcome.
