  1. The leader in session border control for trusted, first class interactive communications

  2. Calculating the ROI for SIP Trunking

  3. Customer case study • Fortune 50 company converted traditional PSTN voice environment to IP • Consolidated 600 disparate PBXs under common management and control platform • Connected platforms into their SIP trunk services • Reduced telephony OpEx by 66% ($12M) annually • Returned capital expense within nine months

  4. Understanding PRI toll and access charges • Access fees reduced • Local outbound toll charges eliminated • LD outbound toll charges eliminated • On-net calls delivered for free • Long distance calls can be routed to local termination point and delivered as local calls PRI and SIP Trunk Charge Comparison Customer’s Before and After Comparison

  5. Understanding access fees • SIP Trunk Access Fees • SIP Trunk monthly access fee for customer is $34/Mo. • No other charges as that fee eliminates local and long distance charges • SIP Trunks sold in units of one • PRI Access Fees • Range from $35 to $52/month and that fee does not include local or long distance charges • Most PRIs are significantly under-utilized since they are generally sold in bundles of 23 usable channels • Recent sampling of customers showed on average their PRI connections running at 40% capacity • Effective unit cost 40% utilized PRI interface is $87 • This means every PRI converted to a SIP trunk will save $53/mo.

  6. Understanding access fees • PRI under-utilization adds up • Customer A has 92K PRI concurrent call capacity but only needs 27.6K • Customer B has 57.5K PRI concurrent call capacity but only needs 28.7K • Customer C has 11.5K PRI concurrent call capacity but only needs 2.8K • Annual savings in all cases is substantial PRI utilization data from three different size customers

  7. Reduced toll charges • SIP trunks bring added cost savings • Move from PRI to SIP trunks reduces long distance and local toll charges • Customer toll charge reductions are almost half of their total savings

  8. ROI calculator • ROI tool available to collect the relevant information and calculate return on investment • Copy of tool is available here:

  9. Information about customer environment Number of PRIs at site Utilization rate of PRIs at site Cost or PRIs Number of concurrent calls at site (from your call detail records) The local outbound minutes per site The outbound long distance minutes per site Information from SIP trunking provider Cost per SIP trunk What else is included with the service Are local outbound calls included? Is there a budget for outbound long-distance included? Are on-net calls (call between your sites) free? Calculating your ROI What is needed to calculate SIP trunking ROI?

  10. Acme Packet is leader in delivering SIP trunking services • SIP trunking availability from APKT service providers exploding • 80 deployments and trials today • 30 countries • Many different IP PBX/UC environments supported • APKT in service provider network + APKT in enterprise network= guaranteed interoperability and faster time-to-trunk • Same border controls for service provider & enterprise • Security • SLA assurance • Service reach/interoperability • All IP trunking protocols supported – RFC 3261 SIP, SIP-I, SIP-T and H.323
