How to block an IP phone

Is there a way to block an IP phone, maybe through a key. I know I may get the same result with extension mobility feature, but the customer is used to the old way.

Re: How to block an IP phone


I need for example, when I step away from my desk, to digit a numeric key to block the ip phone (or through a softkey or whatever) so that no one may use it. And then when I return to be posible to get the ip phone back through a numeric key or a softkey.

Re: How to block an IP phone

Hi Juan,

There is no actual "Locking" mechanism available like on some TDM systems (like Avaya) the closest thing is EM. If the client doesn't like that feature you can try;

You can set up an individual Authorization Code for individuals (FAC) that prevents Toll calls unless the PIN is entered.Have a look;

You can use FAC for colleges, universities, or any business or organization when limiting access to specific classes of calls proves beneficial. Likewise, when you assign unique authorization codes, you can determine which users placed calls. For each user, you specify an authorization code, then enable FAC for relevant route patterns by selecting the appropriate check box and specifying the minimum authorization level for calls through that route pattern. After you update the route patterns in Cisco CallManager Administration, update your dial plan documents to define the FAC-enabled route patterns and configured authorization level.

Adding Forced Authorization Codes

After you design your FAC implementation, you enter authorization codes either in Cisco CallManager Administration or through the Cisco Bulk Administration Tool (BAT). Consider using BAT for large batches of authorization codes; the comma separated values (CSV) file in BAT serves as a blueprint for authorization codes, corresponding names, and corresponding levels. For future reference, make sure that you update your dial plan documents or keep a printout of the CSV file with your dial plan documents.

To add a small number of authorization codes in Cisco CallManager Administration, perform the following steps:



Step 1 In Cisco CallManager Administration, choose Feature > Forced Authorization Code.

Step 2 In the upper, right corner of the window, click the link, Add a New Forced Authorization Code.

Step 3 Configure the authorization codes by using the configuration settings.

Step 4 Click Insert.

Step 5 Repeat Step 2 through Step 4 to add all authorization codes.

Step 6 After you add all authorization codes, see the "Enabling Forced Authorization Codes for Route Patterns" section.

Hope this helps!
