OCS 2007 and different providers RRS feed

  • Question

  • Good morning collegues,
    During our project - deployment OCS we have a few problems,

    1. We noties if clients ( clients I mean users with MS Office Communicator|Live Meeting) works with same ISP so they could establish connection, if they using another ISP they can't, for example we have SouthTelecom Company and one of branches using that ISP, main office using another provider - Megafone.. so .. in main office we have OCS and all other service ... user1 from branch office would like to connect with user2 from the same branch office (both using ISP -   SouthTelecom Company) and they can establish connection... if second user going to main office he will use ISP - Megafone, he try to communicate with user1 and they can't .... what it could be?

    2. We have extrimly slow video streem, why it could be? just two users (point to point) on both side channel speed is ~1 Mbit/s...
    external to external - video quality and audio - perfectly
    internal to Internal - video quality audio - perfectly
    external to internal - video quality so poor, audio perfectly
    (external means users not on the same LAN where is OCS installed)
    (internal means users on the same LAN where is OCS installed)
    both external and internal using credential of the same Win2003 domain...

    any things?

  • Alex, the first thing I would try to discover is the scope (inclusive or exclusive) of the connection problems.  Is the case that only users on a specific ISP can connect to the Edge server while all others can't, or all users can connect except those of a specific ISP.  And what ISP does your main office use?  There could be some strange routing issue related to the IP subnetwork range you chose for the perimeter network where the Edge server sits.  Technically the 'Internet' should be the 'Internet' and it doesn't matter where a client connects from.

    Are there any deployment recommendations or requirements for OCS that you've knowingly not followed for any limiting reason?

    Also, in the second question it appears you may have Internet bandwidth limitation or saturation issues at your office.  Peer-to-peer 2-party audio/video communications travel from client-to-client so external conversations will route video directly between the peers, only sip signalling traffic and IM conversations will travel in/out of your main office.  The same thing happens with internal conversations, the traffic is localized to the LAN.  But internal/external peer-to-peer traffic would flow over the Internet connection as the default route.
