Harvard Phone Program Hits 30% Milestone

May 19, 2017

The Harvard Phone Program Team has converted over 30% of 21,000 targeted University centrex phones to cloud-based Voice-over-Internet Protocol (VoIP) service. Since migrations began in May 2016, 118 Central Admin and School groups have been migrated onto the new service. Installation work has been mainly in Cambridge, Jamaica Plain and Allston but will expand shortly to Longwood Medical Area locations. The Program remains on track to complete all VoIP conversions for remaining Campus groups by second quarter FY 2019.

“Day 2” VoIP Operations Support

The Harvard Phone Operations Team is supporting over 6,500 network based SIP protocol end user devices using newly developed VoIP service request and ebonded Incident Management forms hosted in HUIT’s ServiceNow Service Management system. Access to these support processes and tools is provided to School communications administrators as they are trained on their use as ‘self-service’ system management tools by the Harvard Phone staff. To date, five migrated schools have adopted these VoIP self-service processes as they transition to new VoIP communications support models. 

About Harvard Phone VoIP

Harvard Phone economically provides the University with the latest communications services including ‘my Harvard’ phone number mobility using Cisco’s Jabber services suite. A portal that supports end user ‘self-service’ management of many VoIP services including call forwarding and voice mailbox message notification is also included with the new service.

The VoIP system utilizes Verizon’s “Unified Communications and Collaboration as a Service” (UCCaaS) hosted services platform. The UCCaaS data centers are located in Santa Clara, CA and Beltsville, MD. They connect to the Harvard University Network over high capacity, Multiprotocol Label Switching (MPLS) services that terminate on Verizon routers at HUIT’s 60 Oxford Street, Cambridge and 1 Summer Street, Boston data centers. From that point on, the VoIP service signaling and media runs entirely on the Harvard network. Call set-up signaling and off campus calls are carried to the Verizon network over the MPLS circuits. However, all on-campus, five digit dialed station calls remain on Harvard’s network with no additional switching equipment required, making VoIP a true ‘in the cloud’ service.
