Hi List, I am looking at configuring Asterisk as a SIP server fronted with SER SIP Registrar in a single hardware. If you look at the Asterisk, on one side it handles SIP clients and on the other side it connects to a PSTN gateway over SIP trunk/s. I have few questions. 1. Can we consider this setup as a SIP B2BUA system? 2. I am planning to use HP DL 380 | Dual Quad Core Processor of 2.5GHz | 8GB RAM. What is the maximum number of concurrent calls and calls/sec achievable by this hardware configuration? Please assume that all the other factors are provided sufficiently. Thanks for your help. Cheers, Kannan. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.digium.com/pipermail/asterisk-users/attachments/20120717/fc63a0af/attachment.htm>
