https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/admin/configuration/manual/cmeadm/cmetrans.htmlSure, I'd be happy to explain in detail the two methods to prevent a user from forwarding a corporate number to an international number.
Method 1: Block international dial patterns in the SIP trunk CSS One method to prevent a user from forwarding a corporate number to an international number is to block international dial patterns in the SIP trunk CSS (Call Control Signaling). A SIP trunk CSS is a set of calling search spaces that determine which routes and patterns a call can take. By blocking international dial patterns in the SIP trunk CSS, the call will be restricted from being forwarded to an international number.
For example, suppose the SIP trunk CSS has a partition that includes all international dial patterns. In that case, you can simply remove that partition from the CSS, effectively blocking all international calls. However, this method may not be suitable if there are legitimate international calls that need to be made, as it blocks all international calls.
Method 2: Configure a Forced Authorization Code on the international route pattern Another method to prevent a user from forwarding a corporate number to an international number is to configure a Forced Authorization Code (FAC) on the international route pattern. A FAC is a code that must be entered by the user before a call can be connected. In this case, the FAC would need to be entered before the call could be forwarded to an international number.
For example, suppose you have an international route pattern that is used for all international calls. You can configure a FAC on this route pattern that must be entered before the call can be connected. This method is more precise and flexible than blocking all international calls, as it allows authorized users to make international calls by entering the FAC, while preventing unauthorized users from forwarding calls to international numbers.
It's worth noting that both methods can be used together to provide an additional layer of security. By blocking international dial patterns in the SIP trunk CSS and configuring a FAC on the international route pattern, you can ensure that only authorized users can forward calls to international numbers.
