UB has spent the past few years converting our campus telephone
service to Voice over IP (VoIP). Any phone calls made internally
(from one university office to another) are transported over
UB’s data network, which doesn’t incur telephone
External calls utilize antiquated technology for connections to
the Public Switched Telephone Network (PSTN) via Verizon, however.
This results in more expense for each outbound call and service
recovery from outages is more problematic.
But UB has big plans. CIT is replacing its method of connecting
to the PSTN by using IP-based services for these connections with a
technology called SIP (Session Initiation Protocol) Trunking.
Because of the way SIP Trunking is regulated by the Federal
Communications Commission (FCC), the cost structure for making
calls to the PSTN is much simpler and less expensive. In the event
of a major outage, SIP Trunking will also provide much faster
recovery time: connections can be re-routed from multiple points
rather than a single hub.
CIT team members Dennis Powell, Tom Maniccia, and Tom Jauch have
been working on the project since 2010. This past summer, CIT
conducted a limited trial with campus Internet provider Level 3.
The goal is to incrementally migrate to the new service, but SIP
Trunk technology should be fully in place at UB as early as
Powell added, “We are currently preparing a Request for
Proposals package for service providers to bid on to supply SIP
Trunking to the university. The best outcome we can hope for in
moving to SIP Trunking is that no one but the UB staff paying the
telephone bill will notice the difference.”
