I have a SG300-28P switch and 2901 router with CME configured. I have DHCP configured on the
router which seems to work fine and my Voip phone configuration is configured with just the
basic config to get the phone to register and come up. However my voip phone continues to
say registration in progress. I verified the following is correct:
Auto-registration is disabled on Cisco CallManager.
The Cisco IP Phone is not receiving the DHCP server address.
The Cisco IP Phone is not receiving the IP address, subnet mask or default router address.
The Cisco IP Phone is not receiving the TFTP server.
The Cisco IP Phone is not receiving the correct Cisco CallManager addresses.
The phone still will not register. Is there anything else I should check to get this to work?
