Integrating VOIP, Microsoft Unified Communications and Communicator

Posted on 2010-01-05
Last Modified: 2013-11-29

I am currently in the process of planning out a new office location and have the opportunity to select a new VoIP phone system and I need a recommendation. I would like to select a phone system that intergrates with Exchange 2010 Unified Commiunications and Office Communications Server 2007 R2.  

Does anyone have any suggestions on which phone vendors I should be looking into and does anyone have any experiances with integrating these systems that they would be willing to share with me?

    It depends on what you are looking to do.

    OCS can run as it's own phone system, depending on the features that you require.

    It can also be intergrated with enterprise PBXs such as Nortel and Cisco.

    So it depends on what you are looking to do and the features required to do it.

    i have installed OCS for numerous customers both were OCS is the PBX and were it is intergrated with another PBX.

    What telephone handsets did you go with in an OCS only deployment?  Who was the manufacturer?

    I have to choose everything from the type of circuit that is delivered to the building to the backend devices to the handsets that are on the desk.  I suppose I am looking for a general suggestion that will allow users to pick up the phone and make a call or initiate a call through the OCS software from their computer no matter where they are in the world.  Receiving their voicemails as email attachements is also a feature that we are looking for.  In addition the OCS chat mechinisim and web-conferancing is a plus.

    I have used Cisco IP Phone systems before and like most Cisco products they are overly difficult to configure (for no good reason).  I have also used ShoreTel systems before but I do not know if they integrate with OCS and Exchange Unified Communications.

    Any tips on where I should begin looking are appreciated,

    Accepted Solution

    So with OCS you have a number of options when it comes it handsets and headsets.

    Jabra and Plantronics both do approved headsets and LG-Nortel and Polycom do both an IP Phone or a USB Phone, one of the Polycom models has a dial pad on their USB Phones which some users prefer.

    The selection usually comes down to price and what the user requires.

    To use OCS as a PBX you need to use Exchange 2007 or 2010 for Voicemail and require the Enterrpise CAL for both Exchange and OCS (the Standard CAL is also required).

    In order to use OCS remotley users will either need to VPN in or the prefered option is to deploy the OCS Edge role which allows users to use OCS without needing to VPN in to the network.

    You will also either required a Gateway such as Dialogic or Audiocodes to provide PSTN connectivity or use a Telephony ISP to provide SIP Trunking into OCS, there are some approved ones such as Global Crossing and Interoute.
