In this how to the router will be configured to also act as a DHCP server. Also the VLAN 150 will converted to be able to handle telephony. Also some minor changes will be done on the switch it self in order for it to handle telephony data. Next on some of the commands below are comments to explain what each command does.
Configure DHCP on the router.
configure terminal name of your IP Pool network 192.168.150.0 255.255.255.0 default-router 192.168.15.1 option 150 ip 192.168.150.1 #set raw DHCP options. the 150 is for telephony. end
Configure the router to understand Telephony data
telephony-service max-dn 10 #Maximum directory numbers max-ephones 10 #Maximum phones to support ip source-address 192.168.150.1 port 2000 #The network IP and the default port used. auto assign 1 to 9 #Automatically assigns ext number to buttons end
On the switch Re-configure VLAN-150 from Access port to Voice port and assign port 20 to a phone
interface FastEthernet 0/20 switchport mode access no switchport access vlan 150 switchport voice vlan 150
Configure the router to assign a dial number to the phone
