Is the Asterisk processing and mixing of SIP channels into a single call (simple/minimum, no transcoding etc) calculated in integer or floating point instructions? How much CPU bandwidth is used per call leg, in either MIPS or MFLOPS? How about the G.729 codec, or other codecs: MIPS/MFLOPS? Any ideas how efficient is the Asterisk/x86 code compared to the maximum in the algorithm, that either SW optimization or porting to a more efficient processor (or both) could produce? -- (C) Matthew Rubenstein
