CME Issue

Hi

​

I have cisco 2811 and few 7961G cisco phones, CME verion 8.6, the phones not registering at all, the phone is getting DHCP Address which means connectivity is fine, I have done the following on the router

- NTP is set

- uploaded the phone config file (SCCP41.9-4-2SR1-1S.loads) <<<< could this be a problem

- TFTP Statement on the router (tftp-server flash:SCCP41.9-4-2SR1-1S.loads)

- Loaded the config files (load 7961 SCCP41.9-4-2SR1-1S.loads)

- created cnf file, ephone and dn.

ephone 1

device-security-mode none

mac-address 001E.7AC5.xxxx

type 7960

button 1:1

I have reset the cisco phones, what am I missing

​

Thanks
