CUCM 8.6(2a) and VG204 integration

Suppose your phone network consists of IP phones and analogue phones, you want the phones to inter-call to one another, Cisco Voice Gateway is a simple solution to make this possible.

VG204 has two FE ports and 4 FXS ports, the FXS ports are for connecting analogue telephones, whereas the FE ports are connected to the ethernet which connects back to the Cisco Unified Communication Manager.

Click on Add New.

put in the last 10 mac address of the port fa0/0

Select Analog and choose the 4FXS-SCCP, the port icons will appear. To configure the directory number click on the port icon. For example I click on port 0/0/0.



After you click on the port icon, this page will appear which is to configure your phone number (aka directory number). Each voice port on the VG can configure a directory number to call the analogue phone.

You will see the configured VG204 ports to register to CUCM.
