  • 1. SIP  still  connecting  the  Islands Richard  Shockey Chairman  Board  of  Directors  SIP  Forum Shockey  Consulting 2427  Silver  Fox  Lane Reston,  VA  20291 richard@shockey.us Voice  +1  703  593  2683 Skype/AIM/LinkedIn/Facebook  –  rshockey101
  • 2.  Background • Founded  in  2000 • Leading  Non-­‐Profit  IP  Communications  Industry Association • Membership  comprised  of  Corporate  “Full  Members” that  support  the  Forum  and  pay  annual  dues, Academic  Institutions  and  Individual  “Participant” Members  (free  membership  category) • Help  make  SIP  work  better
  • 3. SIP  Forum  Full  Member  Companies
  • 4. Progress ?
  • 5. The  Evolution  of  Enterprise  VoIP • First  :  Replace  the  RJ-­‐11 – Immediate  gains  in  CAPEX  as  single  wiring  harness  simplifies  campus management. – Greenfield  ROI  –  NO  Brainer • Second  :  Replace  the  TIE  Lines – Integrate  Enterprise  wide  Dial  Plan  Management  into  single  IP Network.  Immediate  OPEX  gains. • Third  :  Replace  the  PRI  (Today)  SIP  Trunking – All  IP  E2E • Fourth  :  Direct  Peering  with  Business  Partners – The  40-­‐40-­‐20  rule • Fifth  :  Seamless  Campus/Mobility  Integration – Its  not  fixed  Mobile  Convergence  its  Substitution
  • 6. PBX  to  SIP  Service  Provider  (SSP) SIP  Trunking • Increasing  progress. • Market  awareness  increasing  monthly  .. • Better  Faster  Cheaper • ROI  is  clearly  demonstrable • 40%  savings  increasingly  reported • SIPforum’s  SIPconnect    1.0  and  soon  1.1 • http://www.sipforum.org/sipconnect • Carrier  support  increasing  among  Incumbents,  CLEC’s  and particularly  MSO’s  (Good  numbers) • So  Long  as    PSTN  (PRI’s)  is  used  as  the  inter-­‐VOIP  “default” network  service  will  be  degraded  as  it  must  transverse multiple  networks
  • 7. Why  SIPconnect?    SIP  is  nearly  150  individual  “Request  for  Comments”  standards from  the  IETF – Nearly  100  more  are  in  the  pipeline • Industry  needed  a  standard  implementable  “profile  of  SIP” • Users  needed  brand  awareness  of  SIP  Trunking  features  and benefits • Maintain  “Voice  Centric”  focus • Strengthen  MUST  vs  SHOULD  ‘requirements  to  implement’ for  both  PBX  and  Service  providers • Create  forum  for  interoperability  compliance
  • 8. SIP  Service  Provider  to  SIP  Service Provider    SIP  Trunking • Class 5 is dying ( its about time) though the FCC hasn’t been told yet. Title 4? • Collapse of Nortel has put Carriers on notice • So what are you going to do with those DMS 250 / 500’s – End of Life letters for 5ESS? • SIP  networks  are  still  being  “Dumbed  Down”  at  the  point  of carrier  interconnection • Considerable progress however.
  • 9. Service  Provider  to  Service  Provider SIP  Trunking • GSM Operators (IPX/Pathfinder) – International Interconnects (i3Forum) and the North American Cable Operators (CableLabs) are in general technical agreement. • Conversion held up due to substantial capital constraints. – The economics in Telecoland not healthy even in mobility. • CAPEX trap. Mobile Data Backhaul dominates. • TN routing data Carrier ENUM initiatives are the looming issues – SIPD base routing still dominates ( Who is the Carrier of Record?)
  • 10. FAX • Ongoing issue • Contrary to popular opinion FAX is still a essential communications service and is actually increasing in popularity due to regulatory requirements ( HIPAA – SOX ) • Sort of works with G.711 – G.729 (no way) or with any HD voice codec. • SIPforum Fax task group coordinating with i3Forum.
  • 11. E.164  resolution • This  is  not  a  ENUM  lecture  ..     • Advanced service delivery based on E.164 numbering will not occur without killing off TCAP/SS7 eventually. • Good  news  its  in  the  field,  well  supported  and  it  works. MMS  success  story • The future of SIP and the teleco industry is tied to making the Voice Service relevant. HD voice needs a new signaling model.
  • 12. OSS/BSS  problems • Architecture is sexy billing systems are not. • Carriers are Spending Millions to accommodate SIP Trunking and in the process canalizing existing revenue. • Number Routing Databases not standardized – Provisioning IP data in intra vs inter carrier routing tables. • In general operational issues related to OSS/BSS are being lost in the shuffle. • CONCLUSION : We still have a long way to go.
  • 13. The  real  industry  problem  is  Layer  8 (financial)      ARPU • Money is the answer what is the question ?
