3CX SIP Configuration Guide
Valcom Session Initiation Protocol (SIP) VIP devices are compatible with 3CX SIP Phone
Systems. The Valcom device is added to the 3CX as a standard SIP extension (generic SIP
phone).
The following steps outline the typical configuration process:
1. Navigate your web browser to the IP address of your 3CX SIP Server.
In this example the 3CX Phone System IP address is: 192.168.96.235
The 3CX SIP Server web access port number is “5481”, by default.
2. Login, using the proper credentials.
In this example we use a default of “admin” for the username and “admin” for the password.
3. Select “Add Extension” from the toolbar in your web browser window.

5. Change the “SIP ID” field to the SIP extension given to the Valcom SIP enabled VIP device.
In this example, we will fill in “9993” for the SIP ID, the same as our “Extension Number” field on the “General”
tab.
Select “OK”, at the bottom of the page, to apply and activate this configuration.
6. After selecting “OK” you will be taken to an “Extension Created” screen which contains the Proxy server IP, SIP
ID, Authentication ID, & Password. You will want to make note of this information.

Phone Number is the same as our Extension Number in the 3CX configuration, “9993”.
Secret is the same as our Password in the 3CX configuration, “password”.
SIP Server Port is the port number, on which the 3CX SIP server is listening for SIP data, as seen in the
“Extension Created” dialog.
SIP Port is the port number, on which the Valcom VIP device is listening for SIP data. By default this is set for
“5060”.
