ALOE Transit SBC Functionality

• Network topology hiding. Efficient hiding of the carrier’s network topology from peering partners to enable the information security (IP address, etc).
• Call authorization by IP address or user name and password, based on data from internal system’s configurations or data from external billing systems.
• Ability to control CPS/RPS value from the carrier’s network
• Privacy support (presentation/screening indicators, RFC3325/RFC4497/Cisco Remote-Party-Id)
• NAT traversal

• Call-by-call transcoding (no need to transcode all calls of a trunk to the same codecs).
• Ability to set codec attributes to be able to interoperate better with vendor’s and customer’s equipment.

Extensive access control allows only the specific pieces of vendor’s and customer’s equipment to access the network thus protecting the internal code and work from outside influence or any malicious attacks. It allows the carrier to let only the specific customers, vendors and data inside the network.

Efficient media routing provides for better control and knowledge of the RTP quality by anchoring RTP to interconnect SBC. Media anchoring allows RTP to flow through the carrier’s network while hiding IP address of the far endpoint.

• Single management point for geographically distributed system
• Efficient load balancing and dynamic re-distribution of workload that allows for efficient usage of hardware resources and increases overall reliability of the system
• Zone traffic manager to ensure number translation and network access

• Multi-protocol support (SIP, H.323) for seamless interoperation with multi-vendor and multi-protocol VoIP equipment.
• Protocol repair for smooth interworking between different interconnect networks.

• Dynamic and static routing between interconnect peers based on a diversity of parameters (ASR, gateway/route load, day of week, time of day, caller ID etc).
• Routing based on received SIP 300/302 redirect messages.
