UC540 transfer calls to Microsoft Lync 2013 Extensions
Thanks for your reply. It's very appreciated.
I actually got the problem resolved. I used "debug ccsip messages" and found out that the system was sending SIP invite messages using sip.skype.com - apparently from a previous Skype sip trunk configuration using CCA that I had done quite some time ago.
I removed the Skype configuration and it still wasn't working. The invites to the Lync Mediation were now going using the data IP which is not what the Lyn server was expecting. This command solved my issue:
I have a DNS entry in my servers that points to the default SIP registrar IP (10.1.1.1). The command also has an option to use the IP directly but I configured Lync to look for the hostname as it's more flexible.
