ALL THE IP PHONES NOT SHOWING IN THE CISCO CME ROUTER (SOLVED)

if all the IP phones are not showing in CME Router. then we will need to configure manually. it is very better to configure manually. all your ephone register with mac-addresses,dns and button. (first clear all the ephone from CME.

1- Unplug the phone

2- remove the ephone 1

3- re-create the ephone 1

4- define the mac-address of the phone

5- now plug back in the phone.

In my case i want to remove  ephone1 from CME

no ephone 1

no mac-address...it is very important

no button. if you know (optional)

no ephone-dn 1

no number
