Hey Guys, A small help needed :) We have the following configuration for our Voip calling card business. Opensips: Handling Authentications of users / load balancing more freeswitch servers in the future Freeswitch : Connected with a billing software through xml_curl Handling call and media Codec used: Between user and Our server : SILK 12k Between Server and outbound gateway : PCMU/PCMA All this is hosted on a XEON e3 1230@3.2Ghz 4 cores And 8GB RAM server. We are using Silk as we found it to be of good call quality and better on bandwith compared to PCMA/U . My query was to know is this configuration enough to handle around 150-200 conc calls ? I know freeswitch is capable of handling a lot more than this but we have Transcoding involved here Silk-->PCMA. Do we have ppl here having similar configuration ? Can they please share their results about concurrent calls ? Thanks And regards Mayank Nakrani
