I have a problem with an application made using the RTC 1.3: it works fine in LCS 2005, but I can not login to an OCS 2007. However, using this user data in a Office Comm. 2007 I can login, so the user seems to be properly created.
When I try to register, I received the 401 and my application does not include an Authenticate header in the 2nd REGISTER message (so I keep receiving 401...). But I can not see any error, and the same application works ("authenticating") in the LCS2005.
I have read that, for using a RTC app in OCS 2007, a user can not have 'Enhanced presence' enabled in the OCS 2007, but it is enabled and grey (can not be modified) in user properties...
I am facing same issue for one user with enhance presence turned on. There are two more user with enhance presence which can login but one is getting exception while changing presence while other one can change presence but can not get presence of other users.
