Voice over IPX or voice over IP Traffic

Voice over IPX (or voice over IP? ) Traffic Survey/Report Update February 12, 2019

Where we stand today Jan 8 th Technology workgroup conference call: Thanga presented the voice over IPX traffic survey and report initiative • • Carry-over item from last year, desire to prioritize & complete Measuring voice over IPX (Vo. IPX traffic / non-IPX Vo. IP traffic + Vo. IPX traffic + TDM voice traffic) • • • Discussed potential survey approach and template • • • End-to-end voice over IPX as a % of total ILD • End-to-end voice over IPX% Voice over IPX mixed with over technologies used to deliver ILD traffic • Inbound voice over IPX% • Outbound voice over IPX% Uncovered issues with i 3 f collect & calculate approach (carrier market share estimates = inaccurate data) Uncovered issues with proposed input template (double counting traffic) Summarized topic and requested feedback from workgroup members (Captured in Meeting Notes) • • • Confirm member interest to pursue further Confirm member interest in using 3 rd party (3 rd party collects and aggregates traffic data) Thoughts on initial ‘mock-up’ traffic input template Summary of Feedback Received: • • • Vodafone – confirmed interest to pursue further and use of 3 rd party, suggested we revisit input template to make more user friendly Telecom Italia – confirmed interest to pursue further and use of 3 rd party Deutsche Telekom – confirmed interest to pursue further and use of 3 rd party Critical question regarding scope has since been raised by Philippe: Is it more meaningful to track and measure voice over IP traffic as a % of total ILD (as opposed to Vo. IPX)? Can we capture both, or if we have to limit to one, is voice over IP preferred to voice over IPX?

Proposed plan moving forward Once scope has been decided… I 3 forum membership wide communication: • • Send communication to entire i 3 f soliciting carrier member participation (Need all carriers from Tech. WG to support and participate in addition to non WG members) Use 3 rd party (Greg) to collect and aggregate carrier member traffic data (all inputs kept anonymous and confidential) Carriers required to provide their traffic inputs in order to receive the aggregate market report Written based Carrier member POCs to review exercise internally (with stakeholders) and confirm participation Communication to provide details regarding the exercise and next steps • What we are doing • Why we are doing it and what you get out of it…. • • • Understand carrier position in IMS service space Bolster carrier readiness Champion acceleration Participating Carriers (and only those that participate) will receive an aggregate market report (voice over IPX market levels and growth rate – actual data, no modeling / assumptions) How we are doing it • • Measure & track voice over IPX growth on scope that included Vo. IPX only, will need to revisit if scope changes Carrier members populate traffic input form Send to 3 rd party for data aggregation (all inputs kept anonymous and confidential – carriers will only see/receive aggregate market results) Simplified traffic input form can be used to repeat exercise going forward Who is involved • • • Project Team (Thanga, Greg, Filippo – collaborate on – i 3 f communication, project plan, input form, carrier member questions) Carrier Member POCs (POCs requested to confirm their company’s participation, facilitate their company’s inputs, send populated form to 3 rd party) 3 rd Party facilitator (Greg – send participating carrier member POCs traffic input form, collect responses, aggregate data, send participating carrier

Proposed traffic input form Simplified form (. xlsx) to capture carrier member traffic inputs: Previous two calendar years (used to establish initial trend) 1. 2. 3. 4. Designed based on scope that included Vo. IPX only, will need to revisit if scope changes Total ILD Voice Minutes - Total annual international long distance voice minutes terminated (incudes wholesale, retail & enterprise traffic, no domestic traffic) Inbound Vo. IPX Minutes - ILD Voice Minutes received from a customer via voice over IPX VLANs Outbound Vo. IPX Minutes - ILD Voice Minutes sent to a supplier via voice over IPX VLANs End to End Vo. IPX Minutes - ILD Voice minutes received directly from a customer via voice over IPX VLANs and sent to a direct supplier (no intermediary supplier used in chain) via voice over IPX VLANs *2, 3, 4 are all subsets of 1 *4 should be exclusive of 2 and 3, to avoid double counting of minutes

Proposed Next Steps • • • Determine Scope – project team (based on inputs from all) Revise i 3 forum communication – project team Revise traffic input form – project team Identify proposed carrier member POCs (complete list below) – project team working with Philippe Determine target timelines for steps mentioned below – project team • • • I 3 forum communication to be sent to all carrier members - Philippe Carrier member confirmation of participation – Carrier Member POC (WE NEED ALL CARRIERS TO PARTICIPATE) Traffic input form sent to participating carrier member POCs - Greg Coordinate carrier member response and send populated traffic input form back to Greg – Carrier Member POC Aggregate responses and send market view to participating carrier member POCs – Greg Proposed Carrier Member POCs: (Identify Leader at each carrier that can drive buy-in & action) AT&T – BICs – BTS – Luis Benavente CITIC – Deutsche Telekom – Markus Balasus Ibasis – Katherine Doe Orange – Cedric Gonin(sp? ) OTEGLOBE – PCCWG – Carlos Dasilva POST – SFR – Nicolas Perone Tata – Christian Michaud Telefonica – Enrique Wong / Francisco Jose Santos Esteras Telenor Telia Telstra Telecom Italia Sparkle – Filippo Cauci TNZI Vodafone – Thanga Durairaj WIS -
