OCS Enterprise Voice Integration RRS feed

  • Question

  • We have OCS 2007 R2 Enterprise Pool in North America. Now we need to provide Enterprise Voice integration for Europe users in Denmark and Norway users. Shall we need to install 2 separate mediation servers one each in each country? What is the best practice to implement enterprise voice for Europe users where the OCS Pool is located in North America.

    Thanks in advance for any help.

  • I don't think you need to have a mediation server local to each country from a technical perspective but you need to understand what if any restrictions there are on handing off VoIP traffic to the PSTN using your own network and you also need to consider other things like providing local numbers to users. So at the very least you are probably looking at termininating a PSTN connection in each country using a gateway that then connects to Lync but I think a "European" pool makes more sense assuming that bandwidth and latency are not an issue.

  • Thank you Alanmad,

    We don't have LYNC, running only OCS 2007 R2. We cannot have Europe pool at this moment. We may plan EUROPE Pool in future for LYNC implementation. 

    This solution is only for around 200 users.

    "termininating a PSTN connection in each country using a gateway that then connects to Lync "

    We have two trunks terminated in two countries. Would you please provide some more details about configuration and normalization rules?

  • Force of habit using Lync. So let's assume that you maintain your current trunks and you just start routing inbound calls to OCS 2007 R2 (assuming that the gateways are supported in OCS 2007 R2). You would then just create two location profiles, one for each site. The corresponding normalization rules would just be whatever you need to accomodate dialing behaviors of users. The last steps are just to create the Phone Usage records and routes.

  • HI,

    It is recommended to deploy a mediation server in the Europe site. The mediation server connects Europe PSTN provider via PSTN gateway.

    You need to create location profile for each site. And create the telephony policy for each site users to let the users' calls to be routed to corresponding gateway.

  • Hi,

    As one of the proposed voice implementation counties don't have SIP trunking from service provider, we would need pstn access. This is situation how can we design voice for both countries?

    One country with SIP trunking and other country with PSTN access. Do we need to install PSTN gateway in second country? Can we use same Mediation server to serve both countries or do we need separate Mediation servers?

    We are planning to use Acme Packet SBC for SIP trunking.Will the below design is an viable solution?

    Thanks for your help.
