OCS 2007 R2 to replace an existing VoIP system? RRS feed

  • Question

  • Hi Ladies and Gents,

    We're currently using a managed system of Polycom Soundpoint 320 phones connecting on their own network / internet connection to an external voip provider. We own the phones but have little to do with the system other than managing users and hunt groups etc.

    We also use OCS 2007 for IM and presence on our user's PCs, laptops and windows mobile phones.

    We're looking at OCS 2007 R2 to replace the system, with it all managed internally and the third party company merely providing the IP <> telephony side of thing.

    I've a few of questions about this.

    • Will we be able to register our Polycom phones with OCS?
    • What would we need to do to them to make them work?
    • Is there a list of compatible devices anywhere?
    • What issues can we expect with the phones being on a different network to our user's PCs? Would it just be a case of situating the OCS server on both networks?
    • Are there any special requirements for the telephony provider to support SIP trunking from OCS as opposed to other providers, or is it a standard method that they will support "out of the box" as it were.

  • Chris,

    Great plan - having already done a few R2 PBX replacements I know you'll be happy with the solution.  Here are the answers to your questions:

  • Will we be able to register our Polycom phones with OCS?
  • Not presently.  My company is nearing completion of a product that will, among other things, allow you to use standard SIP phones with OCS.  Stay tuned.

  • What would we need to do to them to make them work?
  • Is there a list of compatible devices anywhere?

  • What issues can we expect with the phones being on a different network to our user's PCs? Would it just be a case of situating the OCS server on both networks?
  • Our solution would require the Mediation server to be on both networks.

  • Are there any special requirements for the telephony provider to support SIP trunking from OCS as opposed to other providers, or is it a standard method that they will support "out of the box" as it were.
  • As of the R2 launch there are only 4 SIP providers that are compatible with R2 "out of the box."  OCS requires the SIP traffic to take place over TCP, which is not widely supported today.  Our solution will allow you to connect with any (or multiple) SIP trunk provider(s).

    We will be actively seeking beta participants very soon in a widespread fashion but in the meantime your organization seems to be a perfect fit for the beta.  If you are interested, please send a message to smartsip at evangelyze dot net.
