Broadreach Services will use its Microsoft gold partner certification and an alliance with Network Equipment Technologies to add unified communications to existing IP video and voice sites.
The systems integrator, which has been operating for eight years, told CRN it had attained the highest level of membership status in the Microsoft partner program.
It was already a certified Cisco partner, and also had "relationships" with Telstra and Radvision.
"We were going down the path of being a seller of kit but a year ago we decided to change the business strategy and grow our technical capability around [Microsoft's] Office Communications Server," Broadreach's Microsoft practice manager Ben English said.
"We've been working closely with Network Equipment Technologies, who provide universal gateways that allow OCS to communicate with public switched telephony network lines and H.323 endpoints [from the likes of Tandberg and Polycom]."
H.323 is an internet protocol standard for voice and videoconferencing equipment.
Broadreach said it would first focus on selling Microsoft into its existing customer base of videoconferencing customers.
"It's a reasonably straightforward process to get an OCS environment linked up with a H.323 environment," English said.
"With OCS going into the high-definition world, there's a lot of interest in people being able to link it up [with existing IP communication systems]."
Broadreach's sales and marketing manager Steve Kruize said the company had "a few things on the table".
"We're ready to jump into the market," he said.
Broadreach planned to use the next six months to bring the Microsoft side of the business in line with opportunities generated out of its Cisco partnership.
