Take a look on this line of the your DHCP Config:
ip dhcp excluded-address 192.168.2.1 192.168.2.254
No IP address will br provided for your Devices.
2 options here:
set up in your IP Phone a Ip address
Change the range of the IP excluded in your config.
Try:
no ip dhcp excluded-address 192.168.2.1 192.168.2.254
ip dhcp excluded-address 192.168.2.10 192.168.2.254
