Running CME on second hand 2811

[Jensjuulnielsen]

Hi guys

I hope that you can help me. I've bought 10 7975g phones, which I've tried to connect to an Asterisk setup. It's not working as I would like, so I've decided to use Cisco as my central.

I've searched ebay for a Cisco 2811 router as I understand, that I can run the CME software on it. Could you help me figure out which one to buy?

I've searched here: http://www.ebay.de/sch/i.html?_odkw=2811&_from=R40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1311.R1.TR4.TRC2.A0.H1.Xcisco+2811.TRS0&_nkw=cisco+2811&_sacat=0 - would you please point me in the right direction.

Do I need to buy additional licenses?

Thank you very much.

I'm sorry if I've posted this question the wrong place.

This should help: http://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-express/products-device-support-tables-list.html

Click on the software version you would like to run and then you will see all supported hardware and capacities.  Try an older version to support older router like 2811 or 2801.
