DYWIDAG-Systems International (DSI) implements IP telephony connecting its Australian locations. $1,800 per month in cost-savings, improved performance and better reliability.


A more direct, efficient telecommunications system was required to connect DSI’s Australian head office at Newcastle and branches at Emerald, Mackay, Mt Isa, Bassendean (Perth) and Kalgoorlie.

Previously, direct communication between DSI’s locations was impossible as each had its own standalone system, with larger branches using PBXs and smaller Commander systems. This resulted in frequent STD calls between locations at significant cost to the business.

How We’ve Helped

Through Modcoms, a division of Forsythes Technology, we implemented a Mitel MCD IP telephony system. DSI now operates six Mitel controllers, one at each of its Australia-wide locations, connected by a Telstra Wide Area Network (WAN). Now, DSI’s head office and branches are all directly connected nationwide across IP.

Two IP applications – Mitel UC Mobile and Mitel Border Gateway – also allow DSI staff to use their IP solution in smart ways not possible with the previous system. Brenten Smith, DSI’s Systems Administrator, says about 20 staff, typically those on the factory floor or in the depot who spend less time at a desk, have their handsets integrated with their mobiles using Mitel UC Mobile. Both phones ring simultaneously so that no calls are missed.

Mitel Border Gateway allows employees across remote sites to work collaboratively and access distributed company data and expertise, from home, across Australia or across the globe. Currently DSI has a number of Teleworker devices, with full access to voice mail and conferencing.

The Results

Now, DSI’s head office and Australia-wide branches communicate directly with no call costs as everything is IP-based. Brenten Smith estimates that IP telephony saves a typical branch about $1,800 a month in STD call costs per month on top of savings on rental costs.

Another benefit of the single system is branch redundancy, which means that if a controller should fail (none have), DSI’s communications can simply fail over automatically to the controller at another branch, resulting in very limited downtime. The IP phones themselves also offer advantages in functionality.

“With call savings outweighing the monthly rental costs, plus multiple associated benefits, the new IP phone system is yielding valuable savings and improving our communications technology. We are very happy with the handsets which are easy to program and use, and the convenience is impressive. Modcoms are always very competent and professional in their response and service and we are looking to have a long-term relationship with them.”
