  1. Case Study: The ROI of SIP Trunking Date: Tuesday 2/3, 8:30-10:00am Track: SIP-05 –SIP Trunking Room: B114 / B115

  3. Who is Kool Smiles PC? • Kool Smiles PC is a network of local dental offices with a mission to expand access to high quality dental care to underserved children and young adults • Achieved significant ROI and payback in 12 months with a 40% reduction in recurring telephony costs • Accomplished through an IP-PBX upgrade and a SIP trunking deployment with InGate Systems and Bandwidth.com throughout all offices and the centralized call center • What is SIP Trunking? • SIP lines are JUST LIKE T1 lines or POTs lines to the end-user… except better ! • They use the VoIP Protocol and are provided by an ITSP instead of a LEC • You don’t have to buy them in chunks of 23 channels anymore  • They don’t have the same cost structure or geographic restrictions as legacy telephony

  4. Kool Smiles Environment before SIP • Kool Smiles in late 2007… • Growing company • Old style TDM PBX from 3COM fully deployed but lacking features of the newer IP PBX systems • No global address book and distribution lists • No fully redundant configurations : 5-9s of reliability • No unified messaging or hot desking • No centralized management • Telecommunications costs escalating and taking on a bigger percentage of the IT OpEx budget • POTs lines at the locations…. • T1s and long distance in the call center… • IT Budget constraints and headcount pressure starting in 2008

  5. The SIP Solution to Multiple Problems We needed a solution for less headcount, more PBX functionality and less cost ! ? ! Enter SIP Trunking… Just like a phone line, but 40%-60% less ! • Upgrade proposal to Executive Management • Evaluate offerings from Phone Equipment vendors • Evaluate offerings from ITSP vendors and ongoing cost savings • Purchase new Enterprise phone system centralized components and phone lines • Create connectivity between the new system and existing NBX platform • Stage each location to be trained and migrated to the new system • Port phone numbers and consolidate/eliminate un-needed circuits • Benefits • 40-60% per year voice telecom cost savings (reduced costs and reduced lines) • Reduced downtime • Eliminate scalability concerns (10,000+ users) • Feature rich enterprise phone system – better communications • Lower administrative costs – reduce IT headcount

  6. The Partner Search… • Categories to rate vendor solutions • Existing customer base with similar deployments and good references • Unified messaging, find me - follow me, teleworker, ease of use • Reliability, high availability, scalability (10,000+ users) • Centralized management, SIP interoperability, standards and security • Re-use of existing equipment, capex requirements, install complexity • Business disruption risk • Equipment and ITSP service interoperability and security was a key concern • The SIP Trunk solution required some middleware to accomplish all the signaling and security that we needed • InGate systems fit perfectly because of their partnership with our preferred IP PBX Vendor and preferred SIP trunking provider

  9. Lessons Learned • Porting existing phone numbers • Make sure your account is in good standing and completely paid up before issuing any port requests • Notify the losing LEC that the number will be porting and authorize it • Be extra careful if you are moving numbers from a non-facilities based LEC • Check your existing telecom contracts for terms and auto-renewal language • Having QoS on your data network will greatly decrease the probability of voice quality problems • Having robust bandwidth in between your IP PBX and the SIP trunking ITSP will also decrease the probability of voice quality problems • G.729 Codec should be used because of the decreased bandwidth requirements • Plan out your E911 capabilities and test calls to the public safety providers to test the ANI/ALI delivery is correct for each location • Select equipment and services providers that have a proven track record and can provide good reference accounts and great customer service • 5,000,000+ calls since 2/2008 with very few issues
