The Trunk port between the router and switch had to be manually configured using sub-interfaces. Note, however, that the DATA vlan traffic and the phone VOICE vlan traffic for each host is carried over the same link (multiple vlan traffic over the same port). On this segment, the Trunk is formed automatically and is a special form of 802.1q trunk.
Step 6) Configure the Call Manager Express (CME) on the router
The image that is running on the router must support voice services. We are running ios c2800nm-advipservicesk9-mz.151-2.T2.bin in our lab. The output of show version command in Packet Tracer is:

A) Enable the telephony service by entering the command telephony-serviceR1#
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#tele
R1(config)#telephony-service ?
<cr>
R1(config)#telephony-service
R1(config-telephony)#
B) Set the maximum allowable number of ephones (another name for IP Phone) to 2. This can be any number, but the larger the number the more resources is consumed on the router.
R1(config-telephony)#?
auto Define dn range for auto assignment
auto-reg-ephone Enable Ephone Auto-Registration
create create cnf for ethernet phone
exit Exit from telephony config mode
ip Define IP address and port for Telephony-Service/Fallback
keepalive Define keepalive timeout period to unregister IP phones
max-dn Maximum directory numbers supported
max-ephones Define max number of IP phones
no Negate or set default values of a command
R1(config-telephony)#max
R1(config-telephony)#max-eph
R1(config-telephony)#max-ephones ?
<1-42> Maximum phones to support
R1(config-telephony)#max-ephones 2
R1(config-telephony)#
C) Configure the max number of directory numbers.
R1(config-telephony)#max-dn
R1(config-telephony)#max-dn ?
<1-144> Maximum directory numbers supported
R1(config-telephony)#max-dn 20
R1(config-telephony)#
D) Enter the ip address of CME router, the address is the same as option 150 for our setup (10.40.0.1)
R1(config-telephony)#ip ?
source-address Define IP address and port for Telephony-Service/Fallback
R1(config-telephony)#ip sour
R1(config-telephony)#ip source-address ?
A.B.C.D Define IP source address
R1(config-telephony)#ip source-address 10.40.0.1 ?
port Define tcp port for Telephony Service/CM FALLBACK
R1(config-telephony)#ip source-address 10.40.0.1 port
R1(config-telephony)#ip source-address 10.40.0.1 port ?
<2000-9999> Specify the port: 2000 – 9999
R1(config-telephony)#ip source-address 10.40.0.1 port 2000
R1(config-telephony)#

Note that in Packet Tracer, the ephones are automatically created based on the max-ephones command. Here, the mac address is also automatically assigned. On the actual routers, we will need to enter the correct mac addresses.
E) Assign the extension numbers, this is configured under ephone-dn
R1(config)#ephone?

F) Under each ephone, we need to define the phone model (type 7960 in Packet Tracer) and assign buttons to the extensions
R1(config)#ephone 1
R1(config-ephone)#?
button Assign ephone-dn phone lines to phone using format with feature
options.
exit Exit from ephone configuration mode
