My SIP Switch

Hi,

Here is a quick configuration guide for the IP Phone : Siemens C450IP.

Important : Note that there maybe differences in naming or on the path to reach such or such screen depending on the firmware of your phone.

1. Get the connected physically

1st connect the phone to your router and then connect the power cable. This phone is simple so nothing tricky there.

Your phone must get an IP address, so if you are not using a DHCP, make sure to allocate an IP to your phone.

2. Get the phone’s IP address

Go to Menu > Settings > Base > Local Network (or VoIP and then Local Network, depending on your firmware) > Enter the system PIN (default is 0000) > IP Address

3. Connect the the web configuration interface

Open your favorite web browser and in the address bar enter the IP address of your phone

Write down the IP address of your phone and press enter.

You should see the interface below:

4. Enter the system pin

Click on “Settings”.

In IP configuration, by default, you won’t need to change anything. If you are not using a DHCP, then make sure your phone will always get its IP otherwise, you may encounter problems …

5. Telephony settings:

Select “Telephony”, and you should see the screen below:

In “Dial Plans”, you should not have anything to change (since you can handle that better with My SIP Switch).

In “Advanced Settings”, you may want to change things, but later : DTMF options especially (they should NOT be set as “Inband” if you want to use it with My SIP Switch)

Click on “Connections” and then “Edit”

You should see an interface containing the screen below:

Replace yourMSSusername by your actual MySIPSwitch username and edit your password.

Domain and registrar server should be sip.mysipswitch.com

Then press “Set” at the bottom.

If you go back to the page “Connections”, you should see the status as “Registered” (it may take up to 30 seconds)

5. Testing

Now that the phone is registered, you test incoming and outgoing calls.

If you don’t have sound or if the sound is only 1-way. That is more than likely a NAT problem. The 1st thing to try there is to add a STUN server in the configuration of your IP Phone, there are many free ones on the market. One I recommand often is : stun.xten.com
