Ottawa Experts Panel: SIP Trunking Delivers for Mitel

A panel of experts discussed some of the business building and cost savings benefits of SIP trunking at a live event in Ottawa.


Allstream’s traveling panel of SIP trunking experts gathered in Ottawa last week to speak to a group of IT managers and technology professionals about SIP trunking.

The panel discussed Mitel’s complex SIP trunking implementation across their American operations (consisting of more than 50 locations) and the testing protocols Mitel recently ran on its Canadian campus in preparation for SIP implementation here. The panel consisted of Grant Bykowy, Allstream’s Director, Voice and IP Communications Strategy, Brownlee Thomas, Principal Analyst Serving Sourcing & Vendor Management Professionals for Forrester Research, Inc., and customer panelist Sonya Fullarton, Solution Architect with Mitel.

Here are some highlights from the event:

Sonya Fullarton: The Value of Consolidating Network Infrastructure
“In the past Mitel had to have a PBX at each location with separate trunks. In many cases we had a PRI with 23 lines when we didn’t even need that much capacity. With a centralized SIP solution we were able to bring all the trunks into one location and to procure bandwidth strictly for maximum calls that would be going on at any one time across the organization. The ability to centralize management of the infrastructure, reduce the number of trunks we were paying for, and to have area codes where we didn’t have offices was a great benefit. We are paying much lower costs both for the management of the infrastructure and for calling costs.”

Brownlee Thomas: SIP Growth Set to Accelerate
“In the US, 37% of enterprise-level IT decision makers (who are in charge of voice) polled said they are planning to replace PRIs with SIP trunking in the next year, with 18% already having done so. In Canada, 28% are planning to implement SIP, with 15% already there. That’s a big difference, but in 12 months we’re still looking at a potential 48% adoption rate in Canada. That makes SIP ready for prime time, because we approaching a majority of users for this technology.”

Grant Bykowy: SIP Trunking Now Available Over Internet
“A SIP connection can now easily be applied to a single location. When we first launched SIP it was only available over an MPLS network, so it was generally only for those customers using MPLS. We’ve since made it available over the Internet access, and that Internet connection can be single location.”

Brownlee Thomas: Better Voice Management
“The way enterprises often buy voice is through general procurement, not through the IT shop. The IT shop runs the network and the desktop applications, while somebody else in the enterprise owns telephony and cellular. With SIP trunking, we’re pulling telephony and cellular out of general procurement and putting it where it belongs: in IT. We’re saying that we need to integrate voice into the rest of the equation without diminishing the performance and sensitivity of voice.”

Sonya Fullarton: SIP As a New Collaboration Platform
“One of the biggest benefits of SIP trunking is that you can use it as a base to establish other types of media. It’s not just for setting up voice calls, it’s for setting up instant messaging or presence or video communications. With one phone call you can move from voice to video on the same data connection. You can transfer your communications mode and even conference in other parties.
