    Hello,

     

    I'm looking for good ISDN Card with one E1 port and echo cancalation that can work with Office Communications Server 2007. If anyone can help me I will be grateful.

     

    And second question about ip telephones. I picked cisco 7931g and 7940g. Does it work with Communications Server over sip ?

     

    Thank You

    There is not currently a supported card that you can plug into an OCS Meditation server.  However, I have heard of successful implementations with Dialogic media cards.  As a supported alternative you might consider a hybrid gateway, which is basically a Mediation server and media gateway in a single appliance.

    As for your second question, you cannot use SIP phones to register with and communicate through OCS directly.  Only Communicator Phone Edition devices are capable of this.

    Hello,

     

    1. please check my suggestion Calling over ISDN, but read also carefully the warnings.

     

    2. you can use SIP Phones! The genius guys @ snom technology AG, Berlin made it.

     

    They developed the first open standard SIP phone that can register and communicate through OCS directly. (Press Release: May 26th, 2008 )

     

    Please look at http://www.snom.com

     

    or look at youtube for snom ocs edition! http://de.youtube.com/watch?v=Q6CkLVQ2c30

     

    The snom ocs edition is really a limit breaker! The complete 3xx series is now OCS-enabled, simply with a firmware update.

     

    Maybe it will become the "Uber-Tanjay"

     

    SIPoverTCP, TLS, NTLM, SRTP, etc. - they cut the Gordian knot, without lowering security @OCS !

     

    Best regards,
