Thanks but this is really aimed at larger businesses. You need their Access Points for the handsets to talk to and again, it isn't really designed for home use and PSTN connectivity.
These two look quite interesting. I'll try and find out a bit more about these. Thanks.
No good unfortunately. It's not SIP, it's Skype...
Yes - I have looked at these but not read any good reviews. What I have read was not very positive and lots of talk of the devices being "locked" for their 'JOIP' IP telephony network. I'll do a bit more research but the Siemens devices do seem to have an excellent feature set and price.
These guys:

told me they will have the C475IP in stock next Tuesday and the S685IP within 4 - 6 weeks. The S685IP could be a real killer with Bluetooth support too - if I can wait that long

that is.
Anyway thanks again and I'll check out the Broad-tel devices a bit more.
