Creating a CAS NAP

Applies to version(s): v2.9, v2.10, v3.0

Now that you have created a CAS stack, you must create a network access point, in order to finish configuring your system. A Network Access Point (NAP) represents the entry point to another network or destination peer.

To create a network access point (NAP):

1- Click NAPs in the navigation panel

2- Click Create New NAP

3- Configure the new NAP:

• Enter a name for the NAP
• Select a user-created profile, if not, select default
• Click Create

4- Verify that the NAP was successfully created message appears

5- Associate a CAS R2 stack with the NAP:

• Select an interface (the newly-created CAS R2 stack)
• Click the "<<" button to add the interface to the list

6- Select a value for Channel Usage, to avoid call collision

• Click Save

7- Verify that the "NAP was successfully updated" message appears
