SIP feature in OCS/exchange RRS feed

  • Question

  • Hi,
    I am evaluating the possible integration scenarios of our new PBX product (which is not yet in the market) with OCS and exchange.

    For this, I have installed 3 servers (all virtual),

    1) dc01 : domain controller
    2) ocs01: office communication server 2007 standard (NOT R2)
    3) ex01: Exchange 2007 enterprise


    I have also installed the Unified messaging role of exchange server. When I checked the ports of exchange server and OCS server, both of them are listening on SIP port 5060. So, if we integrate our PBX with this system, then to which server should the PBX trunk point to (or connect to)?

    Also, my PBX supports RTCP. So, do I still need a mediation server?

    Thanks & Regards,
    Ashutosh

  • It depends where you host your users
    If you have telephony users with voicemail on the PBX then make a Sip trunk to Exchange UM

    You need another sip trunk to OCS to communicate between OCS and PBX
    If you have telephony users with voicemail on OCS then integrate Exchange and OCS

    You can do both PBX and OCS integration into Exchange

    Mediation Server is always required to integrate between PBX and OCS and you might also require a Gateway if your PBX is not supported for Direct Sip
