How many calls per second can NIST-SIP handle?
NIST-SIP is suitable for most User Agent Applications. It can handle roughly 75 Calls/Second. Thats usually enough for your average desktop phone unless you are an extremely busy person. Proxy server type applications requiring higher thruput are best built as stateless applications (ie. no transactions or dialogs are allocated). There are several optimizations possible including the use of NIO and lazy parsing. These will be implemented as time permits.
