Hi Skunks, This is in relation to Cisco CCME/ VOIP. One of my Cisco POE switches is not working and I thought as a test I would substitute this with a DLink POE switch. The Cisco extensions - 7911, 7945 etc - are switching on but won't register on the call manager. My question is has anyone attempted such a setup before and if it worked how did you do it? Thanks,George
