Hi Juan,

Hope this link helps you out:

Here is an example of the configuration you will need to do. (This is not layed out in exact order)

On the VG204

Interface VLAN 1

IP Address

sccp local VLAN 1

sccp ccm identifier 1 priority 1 <----- The IP Address here would be the IP Address of your CUCME


sccp ccm group 1

bind interface VLAN 1

associate ccm 1 priority 1

stcapp ccm-group 1


ccm-manager config server

ccm-manager config

ccm-manager sccp

ccm-manager sccp local VLAN 1

For every FXS port create a dial-peer as seen below:

Dial-peer voip 1 pots

service stcapp <---- This is what puts the FXS port under SCCP control.

port 0/0/0

On the CUCME (Pre-configured)

Configure the VG204 Gateway on CUCME as seen below:

voice-gateway system  1

network-locale FR

type VG224

mac-address 1234.5678.9999

voice-port 0-23

create cnf-files

For the analog phone you can configure auto-registration if you wish to or manually add the phones.

Automatically register ephones:

Under the Telephony-service add the following command

auto assign 1 to 24 type anl

— Use the type keyword  if you have other phone types in the system and you want only  the  analog endpoints to be assigned to ephone-dns automatically.

To add a ephone manually read the following:

The VG202 and VG204 voice gateways use the MAC address of the Skinny   Call Control Protocol (SCCP) local interface to define unique MAC   addresses for each voice port by using the last 9 digits of the SCCP   local interface of the voice gateway.

For example, if the source interface MAC address is 000C.8639.5833,  the  MAC address of the voice port MAC address will be C863.9583.3XXX.  In the  preceding example, the last 9 digits of the SCCP of the local  VG202 or  VG204 voice gateway become the first 9 digits of the voice  port MAC  address after dropping the leading 000.

The last 3 digits of the voice port MAC address is the slot number   (3-bit) + subunit number (2-bit) + port number (7-bit) in hexadecimal   format. You combine the digits to get the last three MAC address digits.

For example, the voice-port 0/0 is slot number 0 (000): subunit 0 (00) and port number 0 (0000000). By stringing the digits together, you get the following: 0000 0000 0000 = 0 0 0. This means that if the source interface MAC address is 001f.cac3.b3f8, the MAC address of voice port 0/0 will be 1FCAC3b3f8000

Ephone example:

ephone 1

device-security-mode none

mac-address 1234.5678.9000

button 1:1

ephone 2

device-security-mode none

mac-address 1234.5678.9001

button 1:1
