RouterA(config-telephony)#max-ephones 5 #Define the maximum number of phones# RouterA(config-telephony)#max-dn 5 #Define the maximum number of directory numbers# RouterA(config)#telephony-service #Configuring the router for telephony services# You must now configure the Call Manager Express telephony service on RouterA to enable voip on your network. Tasks 2 : Configure the Call Manager Express telephony service on RouterA RouterA(dhcp-config)#option 150 ip 192.168.10.1 #Mandatory for voip configuration.Īfter configuring the ISR router, wait a moment and check that ‘IP Phone 1’ has received an IP address by placing your cursor over the phone until a configuration summary appears. RouterA(dhcp-config)#default-router 192.168.10.1 #The default router IP address# RouterA(config)#ip dhcp pool VOICE #Create DHCP pool named VOICE The DHCP server is needed to provide each IP phone connected to the network with an IP adress and the TFTP server location. RouterA(config)#interface FastEthernet0/0 Don't forget to enable the interface with the no shutdown command ! RouterA>enable
Tasks 1 : Configure interface FastEthernet 0/0 and DHCP server on RouterA (2811 router)Ĭonfigure the FastEthernet 0/0 interface with 192.168.10.1/24 ip address.
Note : Connect only IP Phone 1 at the beginning of the lab.
