Cisco CCNA – Call Manager Express Part 2

16 May 2016

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)#

Here is the show run so far

telephony-service

max-ephones 2

max-dn 20

ip source-address 10.40.0.1 port 2000

ephone 1

device-security-mode none

mac-address 00D0.5813.52EC

ephone 2

device-security-mode none

mac-address 0002.16C5.BB34

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?

ephone ephone-dn

R1(config)#ephone-dn ?

<1-288> ephone-dn tag

R1(config)#ephone-dn 1 ?

<cr>

R1(config)#ephone-dn 1

R1(config-ephone-dn)#%LINK-3-UPDOWN: Interface ephone_dsp DN 1.1, changed state to up

R1(config-ephone-dn)#?

exit Exit from ephone dn configuration mode

no Negate or set default values of a command

number Define E.164 telephone number

R1(config-ephone-dn)#number

R1(config-ephone-dn)#number 4001 ?

<cr>

R1(config-ephone-dn)#number 4001

R1(config-ephone-dn)#exit

R1(config)#

R1(config)#ephone-dn 2

R1(config-ephone-dn)#%LINK-3-UPDOWN: Interface ephone_dsp DN 2.1, changed state to up

R1(config-ephone-dn)#number

R1(config-ephone-dn)#number 4002

R1(config-ephone-dn)#

Here is the show run:

telephony-service

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

mac-address define ethernet phone MAC address

no Negate or set default values of a command

type Define ip-phone type

R1(config-ephone)#type ?

R1(config-ephone)#
%IPPHONE-6-REGISTER: ephone-1 IP:10.45.0.11 Socket:2 DeviceType:Phone has registered.

R1(config-ephone)#

We need to do the same for ephone 2

R1(config)#ephone 2
R1(config-ephone)#?
button Assign ephone-dn phone lines to phone using format with feature
options.
exit Exit from ephone configuration mode

R1(config-ephone)#butt
R1(config-ephone)#button 1:2
R1(config-ephone)#
