  1. 1. A Case Study of Installing 48 E1 with Elastix Belief Mo www.openvox.cn
  2. 2. Agendal  The Background l  The Past l  The Presentl  A Successful Case Study l  The Challenges l  The Solutions l  The Resultsl  The Future
  3. 3. The Backgroundl  The Past l  A brief history l  Asterisk in 2002 l  OpenVox in 2002 l  trixbox CE in 2006 l  FreeIris (Asterisk-based) in 2007 l  AsterCC (Asterisk-based) in 2007 l  FreeSWITCH in 2008 l  Elastix (Chinese Version) in 2010
  4. 4. l  The Present l  Asterisk l  Asterisk Community l  Elastix Community (Largest) l  trixbox Community l  Other asterisk-based software communities l  FreeSWITCH l  FreeSWITCH-CN Google/QQ Group
  5. 5. l  The Percentage of Users (by VoIP88.com)
  6. 6. l  Elastix l  From Zero to Hero l  The Key to No.1 l  Chinese GUI l  Chinese Tech Docs l  Local Manufacturer Support l  Marketing Campaigns
  7. 7. Agendal  The Background l  The Past l  The Presentl  A Successful Case Study l  The Challenges l  The Solutions l  The Resultsl  The Future
  8. 8. A Successful Case Studyl  Implementing 32 E1 Ports in a Single System
  9. 9. A Bigger One
  10. 10. l  Installing 48 E1 in a Single Elastix System
  11. 11. l  The Challenges l  High Density Concurrent Calls l  Asterisk/Elastix is also a Limit
  12. 12. l  The Solutions l  OpenVox D430 (4 Port E1, Advanced Version) l  Adjustable Interrupt Routing Design l  Interrupts Frequency Adjustment l  FPGA Design, Upgradeable Firmware Onsite
  13. 13. l  V1.5 Latest Firmware l  APU (embedded application specific processor unit) l  IRQ Agentl  Elastix
  14. 14. Step 1l  Hardware Configuration l  D430E * 12pcs
  15. 15. l  MB: Intel DBS2600CP2 ( 2 CPUs Supported)
  16. 16. l  Ram: 8GBl  CPU: Intel Xeon E5-2640 @2.5GHz
  17. 17. l  OpenVox PCIe Slot Expansion Board(4 PCIe per board)
  18. 18. l  The Connection
  19. 19. l  Hardware Configuration l  6 D430 set as NET l  6 D430 set as CPE l  Winsip calls NET->E1->CPE->answer and play audio.
  20. 20. Step 2l  Software Configuration l  lspci (recognize D430, must be V1.5 to support 12 cards to work together.)
  21. 21. l  ulimit -n (asterisk supports max 1024 files by default, 12 cards will need 12288 files.)
  22. 22. l  load driver, 1488 channels (31*4*12=1488)l  cat/proc/interrupts {only one(#26) IRQ # is registered by one wct4xxp; it’ll be 12 before IRQ agent}
  23. 23. l  asterisk -rl  pri show spans (48 spans are up)
  24. 24. The Elastix GUIl  The System Info
  25. 25. Hardware Detector
  26. 26. l  Winsip call test (about 3 hours)
  27. 27. l  top (CPU load: 452.4%)
  28. 28. l  The Results l  70%-580% CPU loads l  The System is very stable. l  Great Voice Quality l  The Largest Density Installation that We’ve done with Elastix
  29. 29. Agendal  The Background l  The Past l  The Presentl  A Successful Case Study l  The Challenges l  The Solutions l  The Resultsl  The Future
  30. 30. The Futurel  The Challenge - Are we ready for this fast- growing market? l  OpenVox l  8/16 port E1 products l  Hot-plug VoIP gateway l  Elastix
  31. 31. l  Questions?
  32. 32. l  Thank you!
