    On Tipp from a Lync Guy. DO NOT Change the normalisation within lync to get the dialable phone number, stay with E164 in in the SIP world. If oyu have to stripp of the “+” or countrycode, you should to that on the gateway level. The gateway is the right location, because this knows where it is and knows how to handle NPI and TON (ISDN Parameters). Also for incoming call: The gateway should normalize Caller and Called Number to E164 and forward that to Lync.

    So your blog was by far the most useful in getting out Lync system up and running but I have an odd scenario. I can receive incoming calls but cannot make outgoing. In watching the data flyby in wireshark I can see that the incoming call has 10 digits just as I asked for from tome Telco and the our bound have 10 as well. I followed your guide here step-by-step and again incoming works great outgoing not so much.

    Hi,

    How do you enable IP2IP on mediant 600? Or do we have to? Can you share more detailed setup if it is possible. We receive the logs below.

      Lync uses Exchange 2010 UM to do voicemail, so no, lync doesnt have it’s own voicemail features. It’s pretty easy to setup if you have exchange 2010 in your environment already, but that’s a whole new blog post.
