Asterisk PBX Server’s Benchmarks from TransNexus

Thanks to Jim Dalton from TransNexus for these Benchmarks of Asterisk PBX. Most of our customers want to tune their Asterisk Server in order to get the maximum VoIP call performance with VXI* and they need information about the Asterisk kernel behavior during a stress test. We have added our data about VXI* process %CPU utilization. Of course, it’s an average estimation, because VoiceXML applications can execute very different XML dialogs for each call and can require codec translation too; but the VXI* VoiceXML addon for Asterisk use few CPU compare to the PBX for most of voice interactive applications. Diagrams shows % CPU utilization vs Ports (simultaneous calls) – g711 no codec translation TransNexus document describes a benchmark test and performance results for a standard Asterisk PBX 1.4 working as B2BUA (Back-to-Back User Agent).  The purpose of this stress […]

10th anniversary of VoiceXML, the W3C speech-based interactive application standard mark-up language

Today Agust 25, 2009; marks the 10th anniversary of “the first draft of VoiceXML” (meaning Rev 0.9). There is no question that the W3C-sanctioned standard for a mark-up language for developers of speech-based interactive applications is what makes “Telephony 2.0” possible. With VoiceXML you have all you need to build the sorts of ‘rich phone apps’ at the root of better customer self-service, as well as mobile versions of popular search, messaging and social networking applications. According to OpusResearch  “Foundations” report (issued earlier this year), that businesses will spend roughly $2 billion on speech applications and platforms (both on premises and “in the cloud). Even in this chilly world economy, we see low, double-digit growth in spending as the well-defined standard, coupled with well understood API’s into mature “platforms” fosters proliferation of truly useful (and usable) multi-modal applications that integrate […]
