    Hi Vivek,

     

    Yes, CallManager is quite scalable; in a large cluster up to several thousand end users and devices are supported.

     

    Call Manager versions 4.X and below all run on Windows server. It's a version of windows that ships with call manager (on a ghost-like install disc) and can't be altered, patched or anything unless it comes in a Cisco-approved patch/update.

     

    CallManager 5.X and 6.X are based on a Linux server, although the OS is mostly invisible to the admin. It's all web-based administration. For some reason cisco didn't release CallManager 5 or 6 for the windows platform.

     

    CallManager 7.0 is supposed to be the next release that will be available for both the windows platform and the linux platform.

     

    Regards,

    Matt

    Hi,

     

    I haven't tried these myself but www.3cx.com could work as a IP PBX on windows and seems to be relatively easy to configure. It supports SIP over TCP and UDP.

     

    You can even buy some ip phones to connect to this pbx.. for inbound/outbound dialing you need a voip gateway that will connect up to your 3cx. check out http://www.voiphardware.com/ for some VOIP gateways...

     

    My guess is that it should work with OCS when you use the mediation server..

     

    Sincerely,

    Tonino Bruno

    Hi Vivek,

    Cisco CallManager v. 5.1 works. It's not cheap (especially if this is just for a lab) but it integrates well.

     

    Regards,

    Matt

    Hello Matt,

     

    I think for scalability it might make sense for us to use Cisco Call Manager.  So far we have not tried it. Can Cisco Call Manager be installed on Windows Server? I heard it needs Linux Server (but may be I know too little )

     

    Regards,

    Vivek

    Hello Matt,

     

    Thanks for your post. It proved very helpful. We are going to start by using Call Manager 5.x and see how it works for us.

    Vivek,

     

    I believe Callmanager 6.0 has a lab license already installed when you first install it that allows about 10 phones to be put on the system and it also works in VMware. SIP trunking will work with this license I think. 5.x will only work if you get a license from Cisco.

     Good luck.

    Hello Chaz,

     

    Could you outline the installation process? Their web site does not seem to contain any OCS integration docs.

    Ok they have a forum too and there is a decent thread here

    http://pbxnsip.invisionzone.com/index.php?showtopic=430

     

    You may have to sign up (free) and there is a whole section on MS inter-op

     

    Hopefully that helps

    Hi, I have written a new pbxnsip Wiki page with a guide for pbxnsip-OCS2007 setup. Including helpful screenshots. Take a look, how easy it is:

    By the way, I should mention that OCS doesn't support direct SIP integration with any IP-PBXs. Right now, you need a gateway to integrate. You can see any and all supported gateways here:

     

     

    http://technet.microsoft.com/en-us/office/bb735838.aspx

     

    As I've mentioned elsewhere on the forums, though, you can definitely get the direct SIP integration working with CallManager and PBXNSIP.

     

    Regards,

    Matt

    Thanks a lot! I will definitely give PBXNSIP a try; meanwhile we are using the VOIP functionality using remote call control gateway. By using remote call gateway we do not require a mediation server.
