Hicom 300E Pricing

[jacobsstcg]

We are in the process of looking into migrating from out Siemens HiCom 300e to a 3COM VoIP phone system. In order to finance this we are looking into possiblly selling our HiCom 300e and the phones / accessories. Does anyone here know any avenues to do this through, or what what we might expect to get for a Hicom 300e and Phonemail system with: 500 digital ports, 500 analog ports, 4 T1 cards, 1 remote shelf with 24 digital/24 analog ports, 300 OptiSet Standard Phones and 200 OptiSet Basic phones?

I have been able to find some rough pricing for selling the phones through ebay and such, but other than that any help would be greatly appreciated.

Thanks
Jake
