  1. Hi Mino,

    Nice to meet you and first time to leave a message in here. Recently, i am facing some question on OCS2K7 Capacity planning and deployment scenario. Would you mind share your experience with me? Here is may question.

    Question 1:
    1. I will implement OCS2K7 in next month. Total number of user around 1,200 that all stay in the same location. Mainly feature including IM, Presence, Web and A/V conferencing, Telephony (RCC)with call manager.

    For this question,is it enough if i choose OCS2K7 enterprise edition with consolidated deployment? And is it possible to install on Win2k3 enterprise edition OS with 8GB memory?

    Question 2:
    We have already installed one OCS2k7 server pool on root domain and another OCS pool on child domain. As there is some location problem, we would like to create additional OCS2k7 server pool on the same child domain that means two OCS2k7 server pool will coexist in the same child domain. Is it possible or not? Any conflict on this deployment?

    Thanks a lot for your help.

    Best Regards
    Kenneth Chow

    Dear Kenneth,

    thanks for your comment and yes for sure i will be so happy to help you with anything you need in OCS

    1 – if you will implement OCS next month then please just wait for the OCS R2 which shall be released by mid of Feb , why ? because it will support the X64 bit and this for sure means that it will understand your 8GB , the version available now is 32 bit application which doesnt understand more than 4 GB RAM.
    1 Enterprise Edition Server on R2 will be very good for your 1200 users , however i would really recomend you to cluster that server with another one just for failover.

    2- If you will implement OCS R2 then you should know that there is no in place upgrade , which means that you will have to install OCS R2 on new servers within the same forest pool you have on your root domain then you start moving the users from the old servers to the new servers .

    3- I have been testing the R2 as part of the beta program and the performance is so much better due to the x64 support , which means that i dont think you will need to do root implementation and then child pool implementation , unless you have multiple locations or sepparate organizations from the Legal side.

    4- what i know is that you cant install two OCS Pools serving the same domain whether it is child or root because in the end you will have to create SRV records in the DNS under your domain name and it will map to the 1 OCS pool , also when you install the OCS pool you choose which domain it will server and you cant serve the same domain with 2 diffirent pools .
    well i havent tried this before but i am saying it from the concept side , however i will ask my friends in Microsoft about that and keep you updated.

    meanwhile you better think about the R2 and i would suggest you implement it on the Root and move all users everywhere on it and demote the other OCS servers on the child .

    I hope i have helped a little

  3. Hi Mina Nagy,

    You are so great. Thanks a lot for your suggestion.

    1. As i have already deploy one OCS2k7 in root domain and one OCS2k7 in child domain,is it necessary to do schema extension, forest preparation and domain preparation again if i deploy OCS2k7 R2?

    2. By the way, may i ask the question again about if i deploy OCS2k7 in Win2k3 enterprise edition OS, is it possible to use up to 8GB memory?

    3. Is it possible to create another SRV record which point to the FQDN of new pool name such as pool3.experiencelab.com if i deploy additional OCS server pool in child domain? What’s the impact if i really do it?

    In addition, my one of job duty is specialized in working UC solution both on Cisco and Microsoft. So i would like to take this chance to exchange more experience with each other for further improvement. I have implemented a experience lab for Microsoft UC solution integarte with Cisco call manager and presence server.

    Do you have msn. May i add you? You can send your contact to my email. Thanks

    Yes once you run the R2 setup it will request to extend the schema and forest again because new attributes and features have been added in R2 and they must be added to the Schema .

    2. By the way, may i ask the question again about if i deploy OCS2k7 in Win2k3 enterprise edition OS, is it possible to use up to 8GB memory?

    yes sure , there is no restriction of doing that but you wont get the benifit of the extra RAM because you are using a 32 bit application which only understands till 4 GB . so it will be wastless RAM and will not be consumed even if the server recieved high load of users .

    3. Is it possible to create another SRV record which point to the FQDN of new pool name such as pool3.experiencelab.com if i deploy additional OCS server pool in child domain? What’s the impact if i really do it?

    I would loveeee to exchange information with people and specially with technology geeks as you 🙂
    my msn is minan@mail.link.net

    Hope i have helped , C ya
    the SRV is created under a Zone so that users will get a auto reply when the Communicator tries to lookup for the Service providor uner the specific Zone .
    in this case they will find 2 Host providors with 2 pools , i am not sure the behavior but i am sure it will not be stable . we should tast that for the sake of technology 😀

    Hi,
    We are a Microsoft partner and have access to the ocs r2 builds. Our previous setup included OCS, an avaya s8300, and avaya SES, everything was working. We upgraded to R2, and the only issue we are having is that we do not get any ringback when an incoming call from the pstn targets an OCS user. Once the call is answered, two way talk path is established and there are no other issues. Any ideas on this? I have read that there were some changes to the way early media works in R2, but haven’t been able to figure out exactly what is going on, and if I will be able to get this to work with SES.

    well i have tested this in my lab , and it didnt work right . i was able to ring from AVAYA to OCS but not from OCS to AVAYA.
    i have been into the logs and realised that the IP of the AVAYA SES was in the subnet of 192.168.0.0 and the Mediation with the two network cards are both configured in the same subnet 192.168.0.0 along with the OCS.
    there was a loop on the level on the network which caused that communications between OCS mediation and the PBX were somtimes done by the internal network card of the Mediation which is supposed to talk with OCS FE Server only.
    it is a network issue and it conflicts although i have configured inside the mediation consol which card shall be used for what.
    anyway , i have changed the IP-PBX to 10.0.0.0 Subnet and changed the network card of the mediation facing the PBX in the same subnet and now everything is working fine back and forth and the logs on the mediation are normal.

    Hi Mino,

    So with your SES integration you are not experiancing any ringing issues? I am seeing our issue when users call into either a users ext. or my Conf Bridges I have setup.

  8. Jason said

    I have the same issue as Tony. Calls to OCS conf bridge get no ringing. Im about to call Avaya.
