  Hi,

  Any Number that comes to Lync must be normalized into a destination Number.

  Have you configured a Normalization Rule ?

  Secondly, what number is being routed to Lync Server ?

  That will give you an idea about normalization required.

  If still does not work,Take a wireshark trace or Enable Lync Logging Tool Trace.

  Hi Dan,

  This blog post give the idea of direct sip integrating to a pbx.

  http://windowspbx.blogspot.com/2011/09/using-snom-one-as-sip-trunk-gateway-for.html

  basically start at point III

  (also make sure you don't send the number to lync as a e164 number or lync won't normalize it.)

  Hi,DanMartin,

  
  Successful direct SIP configuration requires the following:

  1)Configuring the IP-PBX to send and receive SIP signaling and media traffic to and from the Mediation Server.
  2)Configuring the Mediation Server to send and receive signaling (SIP) and media (real-time system protocol (SRTP)) traffic to and from the IP-PBX.  

  Before configuring direct SIP, it is very important to have a dial plan structure defined between Lync Server and the IP-PBX. Typically, the IP-PBX supports a shortened dial plan, with extensions that are often a subset of the user’s DID. There may also be variable length extensions and internal numbers that need to be routed to and from the IP-PBX. You can refer the Direct SIP chapter in Lync resource kit book to configure Lync server,details you can check http://blogs.technet.com/b/drrez/archive/2011/06/01/microsoft-lync-server-2010-resource-kit-direct-sip.aspx

  And here is a great blog post talking about configure Lync for RCC with Mitel 3300 just for your reference.

  B/R
