OpenR2 in Asterisk

  1. 1. MFC/R2 free of headaches or your money back OpenR2 in Asterisk Mois´s Silva e Astricon September 2008
  2. 2. MFC/R2 free of headaches or your money back MFC/R2 signalingOutline 1 MFC/R2 signaling 2 R2 in Asterisk 3 OpenR2 in Asterisk 4 OpenR2 Features 5 Closing
  3. 3. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat is it? MFC/R2 or just R2 for its friends. Old days telephony signaling for trunks. Analog and digital versions. Digital version defined by ITU Q.421. Lots of variants around the world.
  4. 4. MFC/R2 free of headaches or your money back MFC/R2 signalingWhere is being used? Old, but widely used. Heavily used in Central and South America (M´xico, e Colombia, Argentina, Brazil etc). Cheaper than ISDN PRI lines. R2 is not going anywhere anytime soon.
  5. 5. MFC/R2 free of headaches or your money back MFC/R2 signalingHow does the digital version work? Uses E1 facilities. Inband MF tones for register signaling. CAS for line supervision signaling.
  6. 6. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants.
  7. 7. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants. Position of CD bits may be different.
  8. 8. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants. Position of CD bits may be different. MF tones mean different things in different countries in different contexts.
  9. 9. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants. Position of CD bits may be different. MF tones mean different things in different countries in different contexts. Some ask DNIS before ANI (and fail when done the other way around).
  10. 10. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants. Position of CD bits may be different. MF tones mean different things in different countries in different contexts. Some ask DNIS before ANI (and fail when done the other way around). Some even use DTMF instead of MF.
  11. 11. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants. Position of CD bits may be different. MF tones mean different things in different countries in different contexts. Some ask DNIS before ANI (and fail when done the other way around). Some even use DTMF instead of MF. Different methods to block collect calls.
  12. 12. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants. Position of CD bits may be different. MF tones mean different things in different countries in different contexts. Some ask DNIS before ANI (and fail when done the other way around). Some even use DTMF instead of MF. Different methods to block collect calls. Different way to notify end of DNIS (MF tone vs timeout).
  13. 13. MFC/R2 free of headaches or your money back MFC/R2 signalingWhat’s the deal with variants? R2 has a scary number of variants. Position of CD bits may be different. MF tones mean different things in different countries in different contexts. Some ask DNIS before ANI (and fail when done the other way around). Some even use DTMF instead of MF. Different methods to block collect calls. Different way to notify end of DNIS (MF tone vs timeout). Some countries do not even regulate its variant.

  15. 15. MFC/R2 free of headaches or your money back R2 in AsteriskAsterisk approach for PSTN signaling. One channel driver to rule them all. Most signaling implemented right into zaptel/chan zap (now DAHDI/chan dahdi). Some with the help of protocol libraries (libpri, libss7).
  16. 16. MFC/R2 free of headaches or your money back R2 in AsteriskAsterisk approach for PSTN signaling. One channel driver to rule them all. Most signaling implemented right into zaptel/chan zap (now DAHDI/chan dahdi). Some with the help of protocol libraries (libpri, libss7).

  18. 18. MFC/R2 free of headaches or your money back R2 in AsteriskUnicall R2 architecture. A different approach. Unicall is an abstraction layer in the form of a simple library. All signaling details are hidden in protocol modules. The channel driver (chan unicall), ideally, interacts with a single signaling interface (libunicall). Ideally, adding a new signaling protocol requires no changes to the Asterisk channel driver.
  19. 19. MFC/R2 free of headaches or your money back R2 in AsteriskUnicall R2 architecture. A different approach. Unicall is an abstraction layer in the form of a simple library. All signaling details are hidden in protocol modules. The channel driver (chan unicall), ideally, interacts with a single signaling interface (libunicall). Ideally, adding a new signaling protocol requires no changes to the Asterisk channel driver.
  20. 20. MFC/R2 free of headaches or your money back R2 in AsteriskUnicall issues. Sad but true. Versioning hell. Multiple components, multiple user errors. GPL license can be sometimes a show-stopper. You need a whole new driver (patching) and libraries just to get R2 working. Poor support.
  21. 21. MFC/R2 free of headaches or your money back R2 in AsteriskDigivoice R2. The Brazilian solution. R2 implementation included in Digivoice library Voicerlib. Support for 3 variants (Brazil, Argentina, M´xico). e Voicerlib Just works with Digivoice cards. Echo issues in their boards.
  22. 22. MFC/R2 free of headaches or your money back R2 in AsteriskPIKA technologies solution. Recent support on their GrandPrix suite. Support for 3 variants (Brazil, Argentina, M´xico). e No 64 bit support. Just works with PIKA boards.

  34. 34. MFC/R2 free of headaches or your money back OpenR2 in AsteriskThe library. Small and functional. LGPL license. LGPL SpanDSP detector embedded into OpenR2. r2test program provided to test R2 links. Works with Zaptel 1.2, 1.4 and DAHDI. No other libraries required (other than libc and libpthread).
  35. 35. MFC/R2 free of headaches or your money back OpenR2 in AsteriskWhere to get it? Branches for Asterisk 1.2, 1.4 and 1.6 Branches available from ’moy’ team branch. Testing of the 3 branches has been done with success in several countries. Plan to merge with trunk someday (Digium decides). Need feedback!
  36. 36. MFC/R2 free of headaches or your money back OpenR2 in AsteriskHow does it fit in Asterisk? OpenR2 fits the same way libpri and libss7 fit into chan zap. Works with Asterisk 1.2, 1.4 and 1.6. chan zap support for R2 only compiled if OpenR2 is present.
