g tables, or in response to messages including a list of multiple destinations (such as a SIP 3xx). Can the SBC perform call routing decisions based on QoS metric calculations on a per segment and per next-hop basis? Describe any ENUM capabilities including local route table storage. Performance The system should meet performance features in the design process and the equipment performance. Ask these questions to determine if your system meets the following: How much latency is added by the product for unencrypted signaling traffic? How much latency is added by the product for encrypted signaling traffic? How much latency is added by the product for unencrypted media traffic? How much latency is added by the product for encrypted media traffic? Is the product capacity constrained by licensing? What is the pricing model for connections, encryption, and any other licensing fea- tures not standard and unlimited with the system? Which model platform would support 1000 users with 250 simultaneous sessions? What are the environmental size, btu, power, and SO on of this previously listed model? Which model platform would support 10,000 users with 2000 simultaneous sessions? What are the environmental size, btu, power, and SO on of this previously listed model? Which model platform would support 50,000 users with 10,000 simultaneous sessions? What are the environmental size, btu, power, and SO on of this previously listed model? The SBC should have the capability to show call duration. SBC should provide a report for every call and summaries to daily, weekly, monthly, and yearly statistics. This report also should present Attempt, Fail, BHCA, and MHT information. The CPU and memory (RAM) utilization should not exceed 70 percent while working at the maximum BHCA. Delivery, Documentation, and Support So far, we have discussed all the technical issues to prepare a good RFP for an SBC. But this is not good enough to select a vendor for your next generation unified communica- tion solution. You need to know the vendor's capab
