    Default Block Internactional Calls


    I want to block international calls eg 90058xxxxx ...

    How do I block all numbers passing through the 900?

    Thank you!

    Dear Glennchot,

    You could do this from call routing. Edit your routing rule for international calls, enable Filter on Source / Modify Caller ID from the first page. In Source Filter / Modify Caller ID - Edit Entry page choose filter type as PBX and choose the extensions which could use these rule. So this configuration would help you give access to international calls only those whom you decide and its also improve your security.
