VOIP exercise

Cisco CCNA Voice exercise

We will follow the next steps:

1.-Configuration of the VLAN

We will create :

VLAN 10 DATA
VLAN 15 VOICE

enable
conf t

vlan database
vlan 10 name data
vlan 15 name voice exit

we will configure the ports connected to the phone

interface f0/5
switchport mode access
switchport access vlan 10
switchport voice vlan 15

interface f0/6
switchport mode access
switchport access vlan 10
switchport voice vlan 15

2.-Configuration of VLAN port

int fa0/5
description Connection to IP Phone 1
exit
int fa0/6
description Connection to Iphone 2
exit
switchport trunk encapsulation dot1q
switchport trunk native VLAN 10
switchport mode trunk
switchport voice VLAN 15
spanning-tree port fast

3.- Configuration of the CME Trunk

conf t
int fa0/1
description Connection to CME
switchport trunk encapsulation dot1q
switchport mode trunk
exit

4.-Configuration of the Router in interface fa0/0

conf t
int fa0/0.10
encapsulation dot1q 10
ip address 10.10.0.1 255.255.255.0
exit
int fa0/0.15
encapsulation dot1q 15
ip address 10.15.0.1 255.255.255.0
exit

5.- Configuration of DHCP

service dhcp
ip dhcp excluded-address 10.10.0.1 10.10.0.10

ip dhcp pool DATA
network 10.10.0.0 255.255.255.0
default-router 10.10.0.1
dns-server 10.10.0.1
exit

ip dhcp excluded-address 10.15.0.1 10.15.0.10
ip dhcp pool Voice
network 10.15.0.0 255.255.255.0
default-router 10.15.0.1
dns-server 10.15.0.1
option 150 ip 10.15.0.1
exit

verification: show ip dhcp binding

UCMM Router

again!now TELEPHONY SERVICE

telephony-service
max-dn ?

max-dn 3

max-ephones 3

ip source-address 10.15.0.1 port 2000

exit

Max dn is the maximum directory numbers

Port 2000 is where the phones communicate with routers

We need to check if the phones got their ip address in 2 ways:

1.-directly on the phone

2.-On the DHCP server type# show ip dhcp binding

Now we will assign numbers

show ephone

ephone-dn 1

number 2001

exit

ephone-dn 2

number 2002

exit

ephone-dn 3

number 2003

exit

We see here an error..Later we found out that in our very specific router model you need to imput the mac address in a specific way.But it was assigning an ip address to our phones to the very specific mac- address
