Since last year when we demonstrated "IMS in Minutes" at TADHack, we've seen tier 1 customers around the world ramp up their adoption of open source software in the core of their network. We'll share several case studies on what Metaswitch Networks and our customers have achieved and the impact on their business.

7. Collaborative team working Onsite support Weekly management calls Voice Design has stood up well What Went Well? Metaswitch Networks | Proprietary and confidential | © 2015 | 7

8. Clearwater has performed well in testing Open source products work in real networks So far the expected business case benefits of NFV & SDN look like delivering 100% Reduced investment & operational Costs Faster time to market Simplified ongoing platform management What Went Well? Metaswitch Networks | Proprietary and confidential | © 2015 | 8 Virtualized product deployment gone well

9. What DIDN’T Go SO Well? Metaswitch Networks | Proprietary and confidential | © 2014 | 9

10. Metaswitch Fixed Line IMS solution didn’t fit neatly into the Manx Network IMS in the real world Manx IMS network doesn’t always follow the specs Had to continue to run existing network Recognition that the end to end solution is key SAAS model was originally confined to IMS core software Metaswitch original view that is a make a “our” software work exercise Not possible to succeed with that approach – need to understand the whole solution for project success. Integration to retained network components Had to develop custom features to match existing function IMS TAS Some complex SIP issues HSS Non standard authentication Had to develop custom features to match existing function Project Challenges - IMS Metaswitch Networks | Proprietary and confidential | © 2014 | 10

11. Initial virtual platform design did not behave as expected Resiliency is much more complex and capable in virtualised world and needs comprehensive testing plan Virtual Networking requires a significant mind set change for traditional networkers Technology is evolving rapidly Project Challenges – I/PAAS Platform for Telco Metaswitch Networks | Proprietary and confidential | © 2015 | 11 Telco operating model needs be clearly understood, Telco guys don’t get Virtualisation Require IT or Cloud team with strong networking skills to support the I/PAAS platform Telco guys own supporting the software application

13. Open Source software Manx early deployment of Clearwater Some teething issues but working well Open Source software works IMS in real world Required flexibility and agility to address issues found in testing IMS can be deployed in multi-vendor environment Virtualization Separating hardware and virtualization layer from applications Virtual networking can be challenging Virtualization works Timelines challenging Some issues have caused delays Project has reached migration phase in 10 months – final hurdle Vendor Perspective Metaswitch Networks | Proprietary and confidential | © 2015 | 13 Manx Telecom has been a great customer to work with Thank You
