Hi, We are currently deploying an entire architecture composed of load balancers, proxies and media relays. All the components except the media relays are Kamailio instances. The media relays are RTP proxy instances. We are trying to determine the hardware requirements for the different servers. We will start with an architecture composed of: · 2 load balancers (one kept as backup to ensure availability) · 2 proxies (load is balanced over the 2 using the DISPATCHER module) · 2 media relays We are trying to determine the recommended hardware for the different components taking into account we will need to serve around 400000 users. How many registrations per second can Kamailio support? How many concurrent calls can Kamailio support? What is the recommended number of children processes? What is the recommended size for PKG memory? What is the recommended size for SHM memory? Thanks for your help, Mickael _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
