2 SIP Trunking A Case Study on Foley & Lardner LLP The Journey Begins Don Lowen Sr. Manager of Engineering & Operations Foley & Lardner LLP
3 Agenda Why take this leap? What are the benefits? The Contenders Design Overview Other Design Considerations. Planned Approach for Implementation Next Steps...
4 But First..About Foley & Lardner LLP Almost 2400 customers (attorney/staff) 21 offices / 18 US-based offices in scope Centralized Call Manager 7.1(5) cluster Redundant PRIs & Gateways at each office location Three MPLS-based WANs / Full mesh topology
6 The Contenders AT & T Verizon Century Link Time Warner Telecom
7 And The Winner Is.. AT & T IPFlex Largest LEC footprint DID Portability Cisco CallManager compatibility Customer References
8 Design Overview Centralized Deployment Model 600 Call Paths Datacenter Redundancy Local Office WAN Redundancy Add IPFlex To AVPN MPLS Network Cisco CUBE Session Border Controller
9 Design Overview
10 Design Considerations Call Paths derived from CallManager RTMT / Carrier Bills G.711 Codec (Planning 100K/call; 35K/call) CoS Review/Bandwidth Review With AT & T / Internal Team Contingency Plan Options Session Border Controller Management Approach Telephony-related applications (Fax)
11 Other Considerations On-Net vs. Off-Net Is a Local Call Really a Local Call? Long Distance; International Pricing Status of Current Carrier Contracts / Extension Mobility Partnerships / Staff Training
12 Implementation Approach On-Premise Design / Cisco Partner Mid-sized Office Pilot(s) AT & T LEC Office Application Testing / Replacing Analog Gateways Aggressive Migration??
13 Next Steps Take Delivery of Upgraded MPLS Circuit in Secondary Datacenter (Router too) Finalize Test Plan Build CUBE Corresponding CallManager Configurations Changes? Knowledge Transfer From Cisco Partner
