Of course you need conversion, unless you plan to hook speaker directly to the other side of the LAN cable and send audio signal through it. If you use wired LAN that is.

VOICE OVER LAN

of course we need to.
the method is called Voice over IP (VoIP), that converts voice data stream into IP packet data stream.
my current final project is "VoIP over VPN (Virtual Private Network)", that uses asterisk VoIP server and X-Lite VoIP client.

Re: VOICE OVER LAN

of course you need to , and DSP's on routers and IP phones do this job using codecs like: G.711 , G.729 ,....

VOICE OVER LAN

IP phones thougether with routers? I wold looking for other way to exit on yours place.

Re: VOICE OVER LAN

Hi

can anyone help me how to configure CISCO 79XX? I need to change the number of my phone.

Re: VOICE OVER LAN

yes you need to modulate you voice signal and this is done by using some protocols that is called Voice over IP, you can send you voice over Internet Protocols. You need to design a VB based server that will get your voice from MIC and will convert it in packets and will send it to LAN same Application will be used on receiver side that will perform receiving and decoding of you voice signal and will send it to speakers.

Re: VOICE OVER LAN

thanks..how to change the phone number?

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 :
