How do I configure outbound route restrictions for calls from users, groups, or sites?

  • Type: Knowledgebase
  • Date changed: 3 years ago

Solution #00006007

Scope:
All Cudatel Communication Servers, firmware versions 2.5 and later.

Answer:

In some scenarios, the Cudatel may need to be configured to block access, or provide alternate routes or providers to certain users or groups. This can be accomplished through the use of route restrictions. Route restrictions allow The Cudatel to restrict outbound calls for a predefined list of approved users to a specific set of routes, or to block outbound calling for predefined numbers. By default, there are no outbound restrictions for internal devices. Once a restriction is added, the Cudatel will add an implied "deny" to the end of the restriction list to deny all members not included.

It is important to remember that the Cudatel will check each route from top to bottom until it finds the first match. If the call attempts and fails, it will then move down to the next option. When using outbound routes, it is important to remember that any restricted route can be followed by an allowed route further down the list in the event that the call attempt fails. This is especially important when considering Emergency routes. The only exception to this rule is the explicit deny, described at the end of this document.

There are two methods used to restrict calls, site-based restrictions and group-based restrictions, with each having a separate focus and use. Both methods are explained below. A third option, an explicit deny, is also covered at the end of this document.

Adding Outbound Route Restrictions for Callers:

When configuring outbound calling restrictions for specific users, groups, or sites the recommended method is to use group restrictions. User calls may include calls from the Call Control Client, User Findme settings, and phone re-directs. These options do not track the IP address of the requestor, ans they are processed from the Cudatel Communication Server internally. Because of this fact, Site-based restrictions are not effective for user management. The following steps cover setting up User restrictions for outbound routes.
  1. Navigate to Extensions > Groups and add the users which you want to allow to a group or groups. Barracuda recommends creating a separate group for routing restrictions to ease future management.
  2. Navigate to Providers > Call Routing
  3. Select the route for which you want to limit access, Click "Add a Restriction" then Add the group(s) of allowed users.
  4. If this route is used by any Automated Attendants, Advanced Calls Routers, or other system calls, check the box labeled "Use this route for system calls."
  5. Repeat these steps for each route which you want to restrict.

Special Conditional Route Restrictions for Emergency (911) calls:

This special route type is for limiting by location for emergency calling. E911 location information is attached to the callerID of the dialing party. Barracuda recommends restricting emergency calling by Site with an individual site, provider, and outbound route configured for each individual site. A multiple site installation should NEVER have an emergency route that is not restricted to a single site, as calls that fail will move the next matching route until they reach an explicit deny, or the end of the route list.
  1. Navigate to Configuration > Sites and confirm that each site exists. Please refer to Solution #00005633 for more information on Sites configuration.
  2. Navigate to Providers > Call Routing
  3. Add an emergency route for the site which you are are configuring for emergency calls, Click "Add a Restriction," then click  Add the desired site.
  4. Repeat these steps for each site needing Emergency Dialing.
Important Note - Barracuda Strongly recommends testing your emergency calling routes after completion, including verifying that the correct call center was reached and that the proper information was displayed on screen after answer. Please check with your provider/local non-emergency police or fire number to confirm local regulations regarding 911 testing prior to making any test calls. Some providers may charge a fee for test calls to emergency numbers, please contact your provider to confirm testing rates and if they allow exceptions.


Explicitly denying outbound routes for Callers:

When configuring outbound calling restrictions to explicitly deny users, we want to add a new outbound route to deny them. The recommended option for this is to create a denial route, also called a bucket route, for the outbound pattern.
  1. Navigate to Extensions > Groups and add the users which you want to allow to a group or groups. Barracuda recommends creating a separate group for routing restrictions to ease future management.
  2. Navigate to Providers > Call Routing
  3. Create
  4. Select the New Route which you just created and click "Add a Restriction" then Add the group(s) of users to be blocked.
  5. Repeat these steps for each outbound dialing pattern which you want to deny.
