  • We would have three fases in deploying OCS2007, first step is having IM/ip telephony for internal users. Second step is connecting OCS with our existing Alcatel PABX.  Third one would be removing our existing PABX and going for a complete VoIP environment.

    For fase II we would go for a little test scenario first and order a seperate ISDN line with our telecom provider. Is there a little Media Gateway out there with only one/two ISDN connections so we can test OCS2007 with a Mediation server and that Media Gateway?
     
    or

     is it possible to have a setup with a sip/pstn gateway where we connect that seperate ISDN line and leave alone the PABX connection? In this scenario we wouldn't use the PABX to have some testing.

    or

    Can we have a setup like this one: OCS2007 + Mediation Server + Media Gateway (Mediant 1000 where you can choose to have separate modules (we need 10 BRI's) and disconnect the PABX?  Can we route/transfer incoming calls on the Media Gateway, or is this why a SIP/PSTN gateways are used?

    Maybe to be clear: in the OCS2007 telephony white paper they use the terms Media Gateway and SIP/PSTN Gateway, who can explain the differences between those two?

    In a third fase we would go for a complete VoIP scenario. Can someone explain what components we need.  From what I learned for different webcasts/documents:

    OCS2007 + Mediation Server + Basic Media Gateway (Mediant 1000) + IP PBX + SIP account with a SIP Service Provider.
    Where do you install the IP PBX, is this software do you need to install it on the Media Gateway or a separate server, are there also hardware IP PBX boxes available and what is advisable?
    If we would like to maintain our 10 msn numbers can we work with a SIP Service Provider to keep these existing numbers (we life in Belgium).? Two of these numbers are faxes, is this possible in a OCS setup and how is the routing done?

  • Hello,

    Can you update this post? Is this still an issue with the RTM version?
