Description of Problem

snom has provided enhanced security features that, depending on the topology of the network you have, may not be necessary for normal use of the phone. The enhanced security settings may make the phone invisible (device not found / unable to detect) to the scan by Flexor or otherwise interfere with setup or operation. 

Solution

Summary

If you are experiencing difficulty adding or configuring snom phones in Flexor and your local area network is already behind a firewall device, for example; your wide area network router that connects to the Internet often provides firewalling, then to confirm that the phone & Flexor can contact each other please implement the suggested security settings detailed below on your snom phone.

The instructions for changing your phone configuration are as follows:

1. Identify the IP address of your phone.
2. Go to the Advanced settings web page of your phone.
3. Make the suggested changes, save the changes.
4. Remove the phone from Flexor Devices and applications (if it has been added).
5. Add the phone via Flexor Devices and applications.
6. Confirm your PCs firewall has exceptions for Flexor if required.

Identify the IP address of your Snom phone

You can identify the IP address from your phone by:

• Pressing the Help button marked ?.
• Press the button under the label IPAdr, the IP address will be displayed.
• Alternatively, Right click on the Flexor icon in the task tray of your PC (usually in the bottom right of the screen) and select Devices and Applications
• Double click on your phone (if it has been added) in the Devices section and your web browser will open on the web interface of your phone.

Go to the Advanced > Qos / Security web page of your phone

Open a web browser and enter the URL of your phone. The URL will be the IP Address of your phone. You can find out the IP Address from the menu on your phone. Then select the advanced option from the menu on the left hand side of the screen, then the Qos/Security tab from the top of the screen. 

Suggested settings:

Ignore security advices - on

Use hidden tags - off

Allow CSTA control - on

Administrator mode - on

Http server username and password - not set

Delete the characters in the HTTP Server Username and Password fields (circled in the example screen shot below) and save the changes with the Save button at the bottom of the screen:

Add / Remove the phone from Flexor Manager

You now need to delete the phone from Flexor and add it again (if you had already added it) or just add (skip to 4th bullet point), if you hadn't:

• Right click the Flexor icon in the bottom right of PC desktop.
• Select Devices and Applications.
• Right Click the Snom phone, select Delete and OK.
• Right click in the blank area under devices and select New Flexor Connect for snom phone.
• Wait for scanning to complete and select the appropriate phone or select Add manually and enter your phones IP address.
