The
facilitates the registration of user equipment (UEs) located on the enterprise network to an IP-PBX in the carrier network. - An enterprise can sometimes exhibit characteristics that are similar to Access/UNI and other times more like a Trunking/NNI .
- The enterprise may implement capability on their network.
- Enterprise may have multiple business locations, these may need to be treated differently from a policy perspective.
- Users may be on a VPN from any internet access location.
Configuration Steps
- UEs located on the enterprise network are configured to register via an to an hosted IP-PBX in the carrier network.
- In this configuration acts in a manner similar to other access/IAD cases. However, there may be additional interoperability considerations with various vendors equipment.
- The IP-PBX acts like a small AS, accepting registration from endpoints and offering services/features. Carrier may virtualize a PBX and support multiple customers on the same system.
