  • A Case Study of Installing48 E1 with ElastixBelief Mowww.openvox.cn
  • Agendal  The Backgroundl  The Pastl  The Presentl  A Successful Case Studyl  The Challengesl  The Solutionsl  The Resultsl  The Future
  • The Backgroundl  The Pastl  A brief historyl  Asterisk in 2002l  OpenVox in 2002l  trixbox CE in 2006l  FreeIris (Asterisk-based) in 2007l  AsterCC (Asterisk-based) in 2007l  FreeSWITCH in 2008l  Elastix (Chinese Version) in 2010
  • l  The Presentl  Asteriskl  Asterisk Communityl  Elastix Community (Largest)l  trixbox Communityl  Other asterisk-based software communitiesl  FreeSWITCHl  FreeSWITCH-CN Google/QQ Group
  • l  The Percentage of Users (by VoIP88.com)
  • l  Elastixl  From Zero to Herol  The Key to No.1l  Chinese GUIl  Chinese Tech Docsl  Local Manufacturer Supportl  Marketing Campaigns
  • Agendal  The Backgroundl  The Pastl  The Presentl  A Successful Case Studyl  The Challengesl  The Solutionsl  The Resultsl  The Future
  • A Successful Case Studyl  Implementing 32 E1 Ports in a Single System
  • A Bigger One
  • l  Installing 48 E1 in a Single Elastix System
  • l  The Challengesl  High Density Concurrent Callsl  Asterisk/Elastix is also a Limit
  • l  The Solutionsl  OpenVox D430 (4 Port E1, Advanced Version)l  Adjustable Interrupt Routing Designl  Interrupts Frequency Adjustmentl  FPGA Design, Upgradeable Firmware Onsite
  • l  V1.5 Latest Firmwarel  APU (embedded application specific processor unit)l  IRQ Agentl  Elastix
  • Step 1l  Hardware Configurationl  D430E * 12pcs
  • l  MB: Intel DBS2600CP2 ( 2 CPUs Supported)
  • l  Ram: 8GBl  CPU: Intel Xeon E5-2640 @2.5GHz
  • l  OpenVox PCIe Slot Expansion Board(4 PCIe perboard)
  • l  The Connection
  • l  Hardware Configurationl  6 D430 set as NETl  6 D430 set as CPEl  Winsip calls NET->E1->CPE->answer and playaudio.
  • Step 2l  Software Configurationl  lspci (recognize D430, must be V1.5 to support 12cards to work together.)
  • l  ulimit -n (asterisk supports max 1024 files bydefault, 12 cards will need 12288 files.)
  • l  load driver, 1488 channels (31*4*12=1488)l  cat/proc/interrupts {only one(#26) IRQ # isregistered by one wct4xxp; it’ll be 12 before IRQagent}
  • l  asterisk -rl  pri show spans (48 spans are up)
  • The Elastix GUIl  The System Info
  • Hardware Detector
  • l  Winsip call test (about 3 hours)
  • l  top (CPU load: 452.4%)
  • l  The Resultsl  70%-580% CPU loadsl  The System is very stable.l  Great Voice Qualityl  The Largest Density Installation that We’ve donewith Elastix
  • Agendal  The Backgroundl  The Pastl  The Presentl  A Successful Case Studyl  The Challengesl  The Solutionsl  The Resultsl  The Future
  • The Futurel  The Challenge - Are we ready for this fast-growing market?l  OpenVoxl  8/16 port E1 productsl  Hot-plug VoIP gatewayl  Elastix
