How Do I Connect It To Microsoft Lync?

November 12, 2013   //   Unified Communications, , , , ,

If you’re considering moving to Microsoft Lync as your Unified Communications solution, there is still a dependency on analog and legacy telephony devices such as common area phones, door phones, elevator lines or overhead paging. Such devices must work with Microsoft Lync endpoints if you want to ensure a successful PBX replacement. SWC has found that solutions provided by vendors such as AudioCodes or SNOM can help.

In order to interface with analog devices, Microsoft Lync needs to have a way to convert its SIP-based signaling and voice streams into a standard phone line. Devices called Media Gateways can accomplish that. Let’s take the example of a door phone and how it would integrate into Microsoft Lync:

  • The door phone connects to Media Gateway via an analog line
  • When a caller presses the Call button on the door phone, the line goes off-hook
  • The Media Gateway auto-dials the Lync Response Group (perhaps a receptionist) upon the line going off-hook
  • The Lync user or group rings, answers and proceeds to talk
  • The Lync user may trigger a door entry relay by passing DTMF tones when pressing # or *

A similar scenario would be used for phones used in elevators or analog common areas like warehouse service phones or emergency phones that can automatically dial 911.

Additionally, these Media Gateways are the interface that enables Lync to talk to legacy PBX systems, which helps in the case of a phased migration. Media Gateways can also be used to have a pool of Fax machines receive faxes through an all-digital SIP trunk or T1 line. Regardless of the scenario, having a Media Gateway as part of your Lync infrastructure enables flexibility and further extends Microsoft Lync’s capacity to function as your business’ Unified Communications platform.
