So you want to federate your Lync environment with Skype….how do you do it.
It’s actually pretty easy assuming your edge is stood up properly. Lets get started.
Step 1: Go register your Lync Access edge with http://pic.lync.com. One important thing to note here is if you have two edge pools, you should register your Access Edge via sip.domain.com. Why, well what if poolA’s edge goes down for whatever reason, all you have to do is update DNS to have sip.domain.com to point to your second edge pool’s Access Edge. Another take away from this is to ensure that the certificates you buy have a SAN entry for sip.domain.com. Even though the link says it may take 30 days, for me it took less than 24hrs.
