I have added my Lync account to my favorites (I cannot find how to add lync accounts to the Skype mobile app but that probably requires the Desktop Client)
I can see the presence clearly in front of the name but the name somehow gets truncated first + last name without any spaces.
I can check the profile where it says Messenger/Microsoft Account which is not correct, this must be Lync Contact
Chat Works as expected
Calling from Lync to Skype on Windows Phone 8
Skype does not recognize the Lync sip address
But the call completes successfull
Dialing from the Skype mobile client on Windows Phone 8 works
Call completes successfull
Bring up the Chat and Profile tab works
The recent call list shows the outgoing call correctly but the incomming call as Unknown Number
Microsoft promised to bring the full Skype integration by june 2013, clearly everything is not functional yet but we are almost there.
Happy Skyping and Lyncing
