I know this is too late for xmas, but there is always next year...
I've only tested this but you should be able to use an IP 2050 Softphone. This is a client which is installed on a PC that uses an IP license and installs like an IP2002/2004. I set it up as an ACD set, acquired it in Symposium, and answered test skillset calls.
If your at home workers have VPN access, they may be able to use this solution.
