Re: How to change Phone Number in VOIP
first you need to set the following toplogy ip phones / analog phones but connect phones to power one by one after finishing configuration:
next you will need to configure your switch with teh following commands :
Switch(config)#interface range fa0/1 – 5
Switch(config-if-range)#switchport mode access
Switch(config-if-range)#switchport voice vlan 1
then we need to configure our router to provide ip address to ip phones and set the calling numbers for phones , we will use CME call manager express embded with router IOS it self.
Router(config)#int fa 0/0
Router(config-if)#ip add 192.168.10.1 255.255.255.0
Router(config-if)#no sh
Router(config-if)#exit
Router(config)#ip dhcp pool voicelab
Router(dhcp-config)#network 192.168.10.0 255.255.255.0
Router(dhcp-config)#default-router 192.168.10.1
Router(dhcp-config)#option 150 ip 192.168.10.1
Router(dhcp-config)#exit
(Cisco recommends to use option 150 rather 066 to obtain the TFTP address to the IP phones
Option 66 only allows 1 host, while option 150 can contain more than 1 ip address, which can be used for TFTP redundancy.)
Router(config)#telephony-service
Router(config-telephony)#max-dn 5 <- max numbers on directory
Router(config-telephony)#max-ephones 5 <-- max number of phones
Router(config-telephony)#ip source-address 192.168.10.1 port 2000 < gateway can be used by phones
Router(config-telephony)#auto assign 4 to 6
Router(config-telephony)#auto assign 1 to 5
Router(config)#ephone-dn 1 <--- phone number 1
Router(config-ephone-dn)#number 54001
(Here you can change number) <--- phone calling number
Router(config)#ephone-dn 2
Router(config-ephone-dn)#number 54002
Router(config)#ephone-dn 3
Router(config-ephone-dn)#number 11111
ok now it should work , i made you the following video (without sound) show you what you must to see if configuration is correct. find attchment or the follwing link :
