what to install to enable voice calls to PDAs ? RRS feed

  • Question

  • Hi all,
    I have OCS R2 implemented and people really likes chat and audio/video conferences. Right now, I would like to take next step and deliver voice calling to PDAs.
    I do not want external calling to landlines or to mobile phones. I just want to keep it inhouse.
    My goal is to enable voice conference on WM phones. Right now I can install OCS mobile client, but cannot make/receive calls with it.
    What role do I have to install to enable it ? Unified communication on Exchange ?
    TIA

    It's not possible to call the Communicator Mobile just over VoIP. The CoMo is only there for IM and 'call control', it cannot actually call. To call a user that is logged in to CoMo, you have to call him on his mobile, cellular number. CoMo will see that the user is in a call then, though.

  • Palars -

    Yes you are required to install serveral OCS R2 roles in order to provide CoMo access to your users.  This includes installing OCSR2 FE/ Mediaiton/ IPGW/ Proxy / Address Book Service - AB Query/ Outside Voice Control.  Unified Messaging and CAS roles are requrired to provide the VoiceMail integration for your EV users.  Remember that all external mobile calls still require your users to utilize the Cellular Network to dial.  This is where OVC comes into play, which helps in establishing an Enterpirse call for CoMo through Mediation server.

    Here is a good overview of how CoMo calls get setup: http://technet.microsoft.com/en-us/library/dd425296(office.13).aspx

    Once you have installed the infrastructure, you will need to add configuration to your Mediation server / FE in terms of  Location profiles, Normalization rules and Policies. 

    If you are looking to deploy OCS R2 Dial In Audio Conference, then your will require to install the OCSR2 CWA server as well since the CWA provides the location profilie / PIN to the end users in OCSR2.

  • OCS Mobile still does not have voice enabled. some of the documentation is a little mis-leading. what actually happens is that when you connect the 2 CWA actually makes the call to your cell phone and the other party you are calling then connects the 2.

  • Thank you all. This finally solves my question. It is a really big disadvantage for OCS mobile not supporting VoIP. I hope 2010 version will support that.  Until then, users have to utilize third party product :(

    Thanks again

  • PalarJ - I'm working towards this also...

    The mobile OC client does not do voice - but you can still use voice on the PDA & get OCS to call back to it not using cell - but it requires infrastructure in place.


    So far, I've got:

    - an Asterisk box between the otuside world & OCS mediation (I can then decide what I want calls to do)
    - a seamless wireless network that support moving between base stations without dropping connections
    - 3 devices to test (Nokia N95, HTC Apache WM6.0, Palm Treo Pro WM 6.1)


    So far - I can get the devices to register with the Asterisk server as a SIP end point (phone).  I can send & receive calls, no problem.  I can walk between wireless points & not drop the call.

    I can set my OC desk client to simaltaniously ring the wireless extension - & it does.  The Asterisk server maintains if the wireless phone is connected & 'alive'. 


    Here's the theory for the rest - when you trigger the PDA OC client to call a contact - the OCS server calls your cell.

    Programming in Asterisk says "When you get a phone call going outbound for this cell, check if this wireless SIP client is connected.  If it is - send the call to it.  If it is not - send it out to the cell number"


    This is all probably a bit too convoluted to setup for most - but I started investigating the possibilities of this & have now reached a point where I think it's all going to work (fingers crossed).

    NOTE - the Nokia built in SIP client is a joy.  The Window Mobile built in SIP client - not so much...
