OCS mediation server with standard sip phones (incl. SIP over TCP) RRS feed

  • Question

  • Dear all,

    I want to now if it is possible to connect standard sip phones (including suppoert for SIP over TCP) to an OCS infrastructure
    without a separate sipserver. As far as I know, the mediation server could be used to transform the RTaudio into G.711 and SRTP into RTP.
    Does anybody of you know if this should work?
    Thanking you in advance for helping me

    best regards,

  • Hi,

    This is not possible right now.
    What you can do is use a gateway like NET VX1200 which supports SIP registration on its own, it works well, you can make SIP to/from Communicator communications.

  • Tomoli,

    Do not waste time and energy researching solutions that are not meant to be one in the first place. Using SIP proxies/registrars adds additional load and point of failure.

    My sense is that the people here that looking for integration with Cisco VoIP do so because they have already existing infrastructure and can't just get rid of it at once. With my respect to the third party VoIP

    PBX developers, being able to interconnect OCS with VoIP provider via middleware does not mean this is the ONLY solution.

    Read this forum from about the beginning of 2007 and come back for discussion.

  • Tomoli,

    There is phones on the market that are compatible with both, SIP standar, and OCS requirements.

    Take a look of snom phones.  They are cheap (around 80 €), and fully compatible with OCS.  They are shipped with 2 different firmwares, one for standar SIP, one for OCS.

    Take a look here -> http://www.snom.com/en/products/microsoft-ocs/snom-ocs-edition-at-a-glance/

  • SmartSIP is another option if you already own SIP phones, would like to use free softphone clients, or want more options in your hardware.
