CSS Line Device Approach: Path Selection
In the previous post I explained how Line Device CSS approach works, but I also mentioned:
- · The Device CSS decides through which gateway/trunk call will go out of our network.
- · Line CSS defines (Class of Service) calling privileges.
In this post we will try to understand how device CSS helps us to select the right gateway. Although Cisco has introduced a concept of local gateway, but we will discuss that in a different post.
