DHCP-Issue

Hi Muhammed Shaf,

Below is a sample config:

!

//The below address are the one's already configured on the CME, and these will be the IP's that you do not want to be assigned to the IP phones

!

ip dhcp excluded-address 10.0.1.12 10.0.1.13

!

//

ip dhcp pool  

network 10.0.1.0 255.255.255.0 

option 150 ip 10.0.1.12  <==== IP address of the TFTP server

default-router 10.0.1.12 <==== Cisco router to which the IP phones are connected

!

Also below is a config guide:

Hope the above helps, and also, if you can please share the configuration from the CME you are working to assign the IP's to the IP phones ?

Regards
